coil suspension vs air suspension mtb

Shock pumps cost around $20-$50. When we sit on the bike the amount the suspension compresses into its travel is known as the sag and it defines the way your bike rides. With a coil shock, you would have to buy different coils with different spring rates, take the suspension apart, and swap them out. The Ripmo sits high in its travel and has very little pedal bob to speak of. I’ll talk more in-depth about this later. Air Springs. The heat can be dangerous as well. This rear coil shock calculator is the closest I’ve found for me on a few bikes. Pedal bob wastes energy by compressing the shock unnecessarily. You should also wipe down the shock after every ride to reduce the liklihood of seal contamination. Ideally, I would never publicly admit that I’ve cased a jump in my life. Modern steel and titanium coils last pretty much forever. This makes it easier to lift the bike off the ground. With coil shocks, they would have to carry a bunch of different springs of different stiffnesses and swap them out. For most riders, that will be every 8-12 months. The modern mountain bike suspension fork is a complicated piece of kit and naturally comprises many moving parts. It may be too stiff. These improve performance but add a considerable amount of weight. The two main types are coil and air suspension forks. The linkages and pivot points are engineered in a way that optimizes the frame’s leverage ratio for more progressive air suspension. The shock can provide progression to reduce bottom outs instead of the frame. That said, coil shocks still offer better performance on long descents because they don’t create nearly as much heat. But one thing they all have in common is the use of rear shocks. They can also deal better with neglect. Harder riders might like about 50 to even 100# heavier than calculated. If the leak gets bad enough, the shock will stop working. It’s not quite as definitive and clear cut as I thought it would be. The shock become stiffer as a result and can’t compress as far. Standard dampers work by forcing oil through a small hole or series of holes (called ports) inside of the shock as the shock compresses and rebounds. This is an expense that you avoid if you go with an air shock because the spring rate is adjustable. Coil shocks have far fewer adjustment options. They are the most common suspension design, by far. Coil shocks require less frequent maintenance. A lot of times I’ve fallen between springs. With the air shock, the bike feels more lively. If you are riding rough terrain with big drops and jumps, you may want to increase your suspension’s progression to reduce the likelihood of bottoming out during a big hit. It adds resistance to the suspension’s air or coil spring force. Some offer both compression and rebound damping. This can be an issue if you want to upgrade your frame. The best mountain bike fork 2021 – We put 9 of the best 170 mm suspension forks to the test to find out which comes out on top! This allows the leverage ratio to change or remain constant throughout the suspension range. Amazon.com : BUCKLOS LUTU 26/27.5/29 Air MTB Suspension Fork, Rebound Adjust Straight Tube 28.6mm QR 9mm Travel 120mm Manual/Crown Lockout Mountain Bike Forks, Ultralight Gas Shock XC Bicycle : … In other words, it reduces the amount of breakaway force that is required to get the shock moving. To adjust the spring rate of a coil shock, you can swap out the metal coil for a stiffer or softer spring. The fluid can last a bit longer because it’s not heating up as much. The leverage curve will be a flat horizontal line when represented on a graph. Finding the right spring rate isn’t always easy. Low-end shocks don’t offer any damping adjustment at all. The majority of mountain bike suspension components use an air chamber; however, it’s not uncommon to have a coil spring instead of air. Air shocks operate more quietly. Because coil shocks don’t heat up as much as air shocks, you don’t have to worry about causing damage from overheating. You'll have to choose between coil and air-sprung for starters. I plan on selling the bike and getting a downhill bike. That said, modern oils are pretty resistant to viscosity changes. Found inside – Page 56The bike is a bit of a sluggish climber; the suspension bobs (adding air pressure to the FOX Boost Valve will firm it up, but at the expense of small-bump ... The stiffness increases at a constant rate throughout the range. But, after riding them back to back, I think I preferred the air shock for 90% of the riding I did. To help you decide, check out our hydraulic suspension vs. air suspension kit comparison below. Today we're back at the pseudo-science to help you decide if you should run a coil or air shock on your mountain bike. The thin oil can more easily flow through the ports in the shock as it compresses and rebounds. Those who like to adjust their suspension often for different terrain, rider weight, and ride feel will appreciate the easy and extensive adjustability of air shocks. Pretty much every full-suspension mountain bike suffers from some level of pedal bob. Stiction is caused by friction from the seals rubbing against moving parts such as the shock shaft. This is done by simply turning a dial on the shock. The anti-squat characteristics of the frame change as the suspension compresses and decompresses while you ride because the leverage rate of the frame and spring rate of the shock change as they travel through their ranges. It also means getting a replacement shock will be easier if it's needed. Come join the discussion about bike parts, components, deals, performance, modifications, classifieds, trails, troubleshooting, maintenance, and more! The times reflect that. A win-win situation if you ask me. They look much more plain. You also want a bike that doesn’t waste energy compressing the suspension unnecessarily. It does increase the likelihood of bottom outs. Found inside – Page 114For a good bicycle suspension , you want something that's progressive : it should get harder to compress as you get closer to the end of the range . I broke it down for just those individual sections and found the air shock was 1.3% slower over roughly 8 seconds in the rocks. Once you hit a bump that reaches the impact threshold, the suspension will activate. Air shocks tend to be a bit more fragile. Most manufacturers recommend that you get your coil shock fully rebuilt once every 100-200 riding hours. 1730 Mission St, Santa Cruz 831.423.9000 - 8035 Soquel Dr, Aptos 831.662.8100. contact@epicentercycling.com. On air forks and shocks, Just a few psi up or down and it feels off. Found insideBicycle suspension works in the same way a motorbike's does: a metal coil or air-filled shock absorber dampens the force of jolts from the ground. My average climb time on the coil shock was 1.7% slower at 2:02.23 than the air shock at 2:02.12. The second version is now coil compatible so it’s a great platform for testing both types of shocks. As the bike accelerates and causes mass-transfer, your body and bike are pushed back, just like sitting in that accelerating sports car. After this test, I could swap between the shocks in under 2.5 minutes. As an added benefit, the performance remains a bit more consistent. You can perform a basic service on your coil or air shock by yourself or take the bike to a shop. At the same time, you don’t want your suspension extending too much during braking. This is achieved mostly through frame design. Most complete full-suspension bikes come with air shocks from the factory. Along with the spring rate, the air pressure also helps to control bottom-out resistance as well as the sag and ride feel of the shock. An air shock can be paired with a frame with either a linear or progressive spring rate. Coil shocks require less breakaway force than air shocks. You should choose an air shock if you ride varied terrain, flatter trails, or terrain that includes lots of uphills. My opinion: if you need something 6+ inches to handle downhill I would go with coil over. I felt that the coil had enough pop to it until I swapped to the air for the first time of the day. Air shocks provide better bottom-out resistance than coil shocks. Those who prefer a smoother and more comfortable ride will appreciate the small bump sensitivity of coil shocks. For a commuter bike like Allant+, they use a carbon/alloy fork with 2.4" high volume tires. Ideally, you want your bike to remain as stable as possible while you pedal and brake. This splits up the load so less heat builds up in the damping system. If you follow racing at all, you've likely seen a big push within the Enduro World Series, with many top Pros making the switch to coil. For these reasons, air shocks are not ideal for downhill and freeride mountain biking. Found inside – Page 35The first job of a suspension system is to absorb impact to allow a bike's ... Manufacturers use polymer rubber elastomers , metal coils , and air and oil ... An issue that the 90s suspension stems suffered was movement under heavy braking. Coils are identified with two numbers. You can adjust the level of progression. On average, an air shock weighs about 300-500 grams (around 0.66-1.1 lbs) less than a comparable coil shock. Push Elevensix rear shock. Found inside – Page 368FOR BICYCLE SUSPENSION FORKS ( U.S. CLS . ... FOR VARIABLE MECHANICAL TRANSMISSION ASSEMBLIES FOR AIR , LAND AND SEA VEHICLES ; COMPONENT PARTS AND FITTINGS ... They can have either a linear leverage ratio or progressive leverage ratio design. A few suspension frame designs that offer progression include linkage-driven single pivot, Horst-link, and twin-link. It is possible that your ideal spring weight sits somewhere between two sizes. Progression adjustment also allows air shocks to work with a wide range of suspension frame designs with different leverage ratios. To help you decide, check out our hydraulic suspension vs. air suspension kit comparison below. In the past, I’ve fancied myself as a coil guy. Both air and coil shocks have a damping system built-in. Pros and Cons of Budget Bikes. A few examples include Pivot, Yeti, Santa Cruz, Transition, and Guerilla Gravity. Some modern shocks come with a new damping technology called platform damping. madhouse. Toward the end of the travel, the leverage ratio might change to 2:1. Found inside – Page 74When he learned of our legs to air suspension . you load it in your van and obsolete by interest in the bikes , Bartels offered to let The fenders are ... Once set, it can be adjusted to better suit your evolving riding style, weather conditions, or unique trail characteristics. The average time on the air shock was 1:20.60, 1.4% slower. There isn’t enough progression in the system to prevent this. Even coil-over shocks and coil-sprung forks can benefit from a negative spring, though they’re less common on mountain bikes these days (we’ll explain why). As the suspension moves throughout its range, it becomes exponentially harder to compress. Found insideRefer to the owner's manual or data online for details of your suspension unit ... First things first – we must set the air pressure or spring weight so the ... Coil shocks also aren’t compatible with all frames due to the linear leverage ratio. So what I’m getting at is an air shock is probably better for the majority of riders out there. Rider weight has an impact on the setup, the terrain you ride impacts on the travel you need. You want to adjust your suspension so bottom outs are rare. With an air shock, you can set the exact spring rate or stiffness you desire. For years, air shocks have been standard in mountain biking. Coil shocks were reserved almost exclusively on downhill mountain bikes. Some believed that air shocks would replace coil shocks completely. After all, if you walk into any bike shop, you’ll notice that pretty much all of the mountain bikes come with an air shock. Particularly among enduro and trail riders. Most modern air shocks also have internal floating pistons (IFP) that move the oil and gas (usually nitrogen) away from the main part of the shock. This is the case because air shocks are more adjustable, easier to adjust, and more popular. “You’re much more in control on the bike because the suspension is more responsive to the terrain,” explains Paul Byrom. Be sure to check with the Ibis website to see which ones will work. Disclosure: Please note that some of the links in this post are affiliate links, including links from the Amazon Serivices LLC Associates Program. 2) Coil suspensions are a fraction of the price. Coil shocks offer a more comfortable ride than air shocks. This allows heat to dissipate more easily. Copyright 2021 - Where The Road Forks. It used to be if you needed longer travel you had to go with coil over and air was used for shorter travel bikes and lighter weight. The suspension rebounds back as you finish the stroke. This makes the ride a bit more rough and bouncy. Fox Racing Shox 32 Float SC 29 FIT4. Fox Racing Shox 32 Float SC 29 FIT4 at a Glance: Travel: 100-120mm. For example, on a frame with a 3:1 linear leverage ratio, the rear wheel would move 3 inches while the shock compressed 1 inch. Some offer a compression damping adjustment as well. You can adjust the suspension to operate almost linearly until the end of the range by removing spacers to increase the volume in the chamber. Plus, it’s lighter and generally, easier to tune. The oil flows faster through a larger hole and slower through a smaller hole. Found inside – Page 234An Illustrated History of the Bicycle Lance Armstrong ... Where the big air huckers were using coil - sprung , wet - bath suspension parts to get up to 10 ... Easy Drop-In Installation. As you can imagine, there is an enormous amount of customization you can make to a the suspension ratios between frame designs, suspension designs, and suspension adjustments. The spring rate ‘ramps up.’ Toward the end of the suspension range, it takes an enormous amount of force to further compress the air inside of the shock. This allows maintenance intervals to be longer. Disadvantages of coil springs compared to air Weight. This test was the tightest of all the timed tests. Increased traction allows you to take corners harder and faster without having to worry as much about your wheel sliding out from under you. Suspension comes mainly in two forms: coil sprung or air sprung, although elastomers still get a look-in on low-cost forks. If you’re bottoming out too often, increase the pressure or progression in your air shock or install a stiffer coil to your coil shock. The spring ratio curve of the shock, the leverage ratio curve of the frame, and the adjustment of the shock together all play a major role in the way the bike feels while riding. This gives you excellent small bump compliance for gobs of traction and control. You may want to set your air shock’s spring rate to suit the type of terrain you’re riding that day. The bike also feels more stable while riding over bumps. It’s more important on air-sprung suspension because it takes a lot of force to overcome a pressurized chamber and start it moving. Pedal kickback happens when the cranks try to rotate backward when the suspension compresses. Generally, air shocks create more heat than coil shocks because they have more seals. But here they depart in terms of compression vectors, which tend to be progressive in air shocks, while linear in (most) coil springs. The suspension is designed to ignore any forces below that threshold. Also, the lack of friction in the initial stroke is pretty apparent. PowerJrod Ram Guru. The spring system is unlike anything out there in the gravity suspension world. This is possible thanks to the greater sensitivity that coil shocks offer. During a drop, jump, or hard hit, you can fully compress the spring and bottom out a coil shock. Air shocks use the compression resistance of pressurized air for shock absorption. If you ride competitively or just like to ride as fast as possible, you may be a bit better off with a coil shock. The bike also feels a bit more supportive. Once for each wheel.) I'm running a Roco tst-r coil on the rear. You’re not going to carry an extra spring and swap them out by the side of the trail. It’s also easier to buy a bike if you go with an air shock because pretty much every frame is compatible. The weight difference also depends on the spring rate of the coils. Found inside – Page 5IT'S FULLY LOADED WITH FOX DUAL RATE CONTROL VALVE SHOCK, A DUAL CANISTER AIR SHOCK THAT FEELS LIKE COIL SUSPENSION, BUT WITH THE BENEFITS OF AN AIR SHOCK. The ideal progression setting depends on your frame design as well as the terrain you plan to ride. Coil shocks have a linear spring rate. I experienced more hard bottom outs on the coil shock than the air. Air cans and metal springs are both effective ways of creating a mountain bike shock. For example, you can set your suspension so it becomes hard to compress early in the range by adding spacers to decrease the volume of the air chamber. Found inside – Page 20As air-sprung suspension technology improves people are starting to favour air springs over coils due to the adjustability and weightsaving advantage. Those who prefer a bouncy and playful shock will also prefer the progression of air shocks. Coil vs Air Ride Quality. Manufacturers are also finding ways to reduce friction so the shock creates less heat to begin with. As an added benefit to bump sensitivity, coil suspension offers better traction. Of course, if you ride frequently, you’ll have to perform maintenance more often. On a graph, a progressive leverage curve is represented with a downward sloping line. The patent pending design provides a near linear compression curve for a “coil-like” feel while maintaining infinite adjustability. An air shock may not react to a small bump that doesn’t create enough force to break the stiction. So I wanted to see if I could find some other factor that would make it easier to give a recommendation on coil vs air. Airsprings are much more common on XC, trail, and all-mountain bikes, due to their lighter weight and easy tunability (i.e. Found inside – Page 18'pre-lod Preload is the amount of compression a suspension's spring (coil or air) is under before any additional external pressure (like rider weight) is ... These frames pair well with air shocks because the shock can provide progression to reduce bottom-outs. This makes the ride feel a bit more harsh. That said, there are some situations where an air shock might allow you to ride faster than a coil shock. For example, maybe you want to use the same bike for fully-loaded bikepacking and trail riding. Coil shocks were reserved almost exclusively on downhill mountain bikes. This allows the damping performance to remain more consistent. Coil shocks are popular among downhill mountain bikers. To make these adjustments to an air shock, you don’t need to buy any extra parts or take the shock apart. Excessive heat buildup can even cause internal damage to the shock. Coil vs air shocks. How to choose the best budget mountain bike forks How much do suspension forks cost? Some riders prefer the looks of coil shocks. Found insideThere aretwo ways of suspending abike: airsprung; andcoilsprung. Air sprung means thatthere is no physical springon the suspension unit; instead, ... There are shades of grey within all of these variables as well as how they intersect, but both of them should be factored into your decision between air and coil. Determining leverage ratio is actually quite simple: take the total rear travel and divide it by the shock stroke travel. The coil handled the jumps well enough, but I noticed a few hard bottom outs. For years, air shocks have been standard in mountain biking. You should choose a coil shock if you ride downhill, enduro, or just like to ride fast. 2002 Continental with the semi active suspension. The amount of damping adjustment that is possible depends on the shock. Generally, coil shocks are a bit more durable and long-lasting than air shocks. There are compromises. It sets the base level for the air or coil spring pressure in your fork or shock. Springs are identified with two numbers. Coil springs, on the other hand, are more popular among the DH crowd—where weight is less of an issue—because of their unmatched small bump sensitivity and bomb-proof construction. Increasing the air pressure makes the shock feel stiffer. The leverage ratio is the ratio between the distance the rear wheel travels in relation to the distance the shock travels. The reason is that they can’t absorb some small bumps due to stiction. Some suspension bike frames are not compatible with coil shocks. Tech Trail - This trail has tighter, flatter corners, a few rock and wood features, and most importantly rock gardens. Where do you stand on the coil shock vs air shock debate? Most coils have 2-3.5″ of travel. The Redshift ShockStop suspension seatpost is an internal coil sprung suspension seatpost that operates on a four-bar linkage system and promises to smooth out the rough stuff and reduce fatigue. Coil shocks can bottom out more easily than air shocks because spring rate is linear. When you pedal, your weight shifts back and compresses the suspension. The thick metal coil spring looks pretty cool. They can have either a linear leverage ratio or progressive leverage ratio design. 10:36. Found inside – Page 5Gasoline automobile Pneumatic tire Bias tire Radial tire Steel radial tire Torsion beam suspension Link coil suspension Double wishbone McPherson strut ... The chain tries to pull the chainring backward causing the cranks to rotate backward. Found inside – Page 67Suspension Almost all mountain bikes utilize front suspension , which allows ... air to an air shock or fork , or changing the spring in a coil sprung shock ... When a shock continuously compresses and decompresses, friction between the seals and moving parts cause the system to heat up. Found inside – Page 14On touring bikes, however, the use of additional air pressure is quite effective for ... Coil‐type springs are used in most motorcycle suspension. MRP Suspension - Mountain Bike Spring Rate Calculator. Mostly small. The leverage ratio would remain the same everywhere in the suspension’s travel. In some cases, it may be possible to swap out a linkage on your existing bike frame to make it more progressive and compatible with a coil shock. Particularly while riding rough sections of trail. The linear leverage ratio frame relies on the progression of the air shock to provide bottom-out resistance. The amount of force required to break the stiction and make the suspension begin compressing is called breakaway force. This extra maintenance is necessary because air shocks have more internal seals. This involves topping up the oil, cleaning or replacing the seals. In this case, the suspension would be too stiff for normal use, causing the ride to feel harsh. Whether it is a fork or rear shock , you will be amazed at the technology these days in suspension, and how having a quality product gives you the confidence to shred harder than ever before. This means a great deal of expense any time anything needs to be serviced or replaced. Air shocks have come a long way in the burly department. When a shock absorber compresses and rebounds, it creates friction. This guide starts by listing the best rear shocks for mountain biking from companies like Fox, RockShox, Marzocchi and DVO. Many coil shocks also allow you to adjust the rebound damping. DVO is a young company that is backed by years of experience in the bicycle industry. 2 cycles with the air shock and 2 with the spring one. This is possible thanks to the progressive spring rate of air shocks. Many air shocks also allow you to adjust the compression and rebound damping as well. And doubles I can’t seem to clear to dave my life. I didn’t notice any hard clangs on the air shock. The hole size controls the rate that the oil can flow. If you ride competitively, an extra second or two might make the difference between winning or losing a race. You can’t easily adjust the suspension if you gain or lose weight or decide to mount some bikepacking bags. Just remember that there is both PSI and rebound to tune. Preload. The progressive spring rate of air shocks makes them ideal for those who jump or ride off large drops. Air shocks don’t provide quite as much grip. If you look at almost any manufacturer’s line of full-suspension bikes, you’ll notice that almost every model comes with an air shock. Whether you choose an air shock or coil shock, I hope this guide has helped you in making your decision. Sep 29, 2020 #1 Does the air suspension have less articulation/flex than coil? When you hit a bump, a coil shock can also react faster. I realize our number are small here. They are less common on downhill bikes. That’s the only way I could think to quantify the difference in pop between the two shocks. Excessive heat can cause the damping performance to fade. I like the grounded feel in rock gardens, roots, and bumps. I liked the energetic feel of the air shock and how well it did on the jumps. This is possible due to the superior small bump sensitivity. In either case the advantage of having a suspension … A complete shock overhaul for a coil or air shock typically involves taking the shock apart, inspecting all of the parts, replacing all of the seals, and replacing the shock fluid. They are making a comeback on trail and enduro bikes. Fox Racing Shox 32 Float SC 29 FIT4. Shocks with platform damping can be adjusted with a dial. Outside heat combined with heat created by the shock can cause performance to fade. Most coil and air shocks allow you to adjust the damping for the terrain and your weight. Racers and non-jumpers might be better suited with a coil. Found inside – Page 236Coil Spring in Tension brands , but there are many more . ... An interesting variant of the pneumatic suspension principle is the Firestone pneumatic ... There is a compromise. I think the coil advantage is most if you prefer softer suspension and if you ride mostly hardpack with small to medium rocky sections. Coil shocks are more sensitive to small bumps than air shocks. The oil can also degrade. I presume that this effect is lessened on the latest generation of products given how much less suspension travel there is. Coil shocks require less effort to start them moving, and that effort doesn’t ramp up as quickly as with air shocks- this means they require less dampening to provide better traction and bike control. This changes the speed that oil can flow through the damper, which changes the speed that the shock compresses and rebounds. The differences in ride quality were apparent again. For this reason, many companies optimize their frames to reduce anti-rise. Letting air out makes it feel softer. Found inside – Page 12Mountain bike suspension technology is very similar to what's found on modern ... If your bike is air sprung, just borrow a shock pump from someone and set ... The fluid becomes thinner, which makes the damping system less effective. Coil shocks offer the best performance in most situations. Full Member. Piggybacking shocks also have two compression circuits. Setting your rear shock sag Before you start make sure your rear shock is in ‘fully open’ mode (if you have a low-speed compression adjuster wind it fully in the [-] direction). Found inside – Page 37use either a coil spring or a chamber of compressed air to give a fork its bounce, ... In your suspension fork, air can be used as a spring by inflating a ... Coil shocks are heavier but give a much more supple feel on the trail. Air shocks are lighter because they don’t have a heavy metal coil. You simply connect the pump to a valve on the shock and push air in or let air out. This heat also causes the oil in the damping system to heat up. The simplest suspension frame design, called single-pivot suspension, operates linearly. Surprisingly, air shocks are heavier than they were in the past due to advanced systems like piggyback chambers and negative springs. We love bikes and are your one stop for all things bicycle-related! Coil front and rear is much more time consuming to tune and can take many spring swaps, and damping and preload tweaking to get a nice balance front to rear using full travel and without excessive bob and wallow. Coil: Coil. ... air and coil springs. I'm not sure why that shock is so popular because it doesn't perform very well compared to others. This allows for a smoother ride. You can just set your suspension up and leave it as is. As someone who has never ridden a bike with coil suspension, I am wondering if there is a major difference between air and coil shocks. They can get contaminated with dust, dirt, and grime more easily. Air shock may not react to small bumps. The choice between coil vs air shocks is similar to the debate between flat vs clipless pedals or 650b vs 29” wheels. If you don’t keep up on maintenance, the seals begin leaking air. JavaScript is disabled. Found inside – Page 62Even the final drive ratios are the same for all three bikes at ... Air suspension also provides highly progressive springing. so the more it gets ... You’re essentially wasting energy compressing the suspension that could be used to drive you forward. I've begun to notice that the rear suspension no longer releases when I park car. On these frames, the ratio between the rear wheel movement and the suspension travel remains constant throughout the suspension range. These adjustments are called rebound damping and compression dampening. Cart. For example, if it takes 500N of force to move the suspension 5cm, it would take 1000N of force to move the suspension 10cm.
