air fork vs coil fork weight

The test was performed on a 2017 Specialized Enduro S-Works 29'r. I found it a bit too firm on a lot of the lower grade high speed trails I was riding so I swapped it out for a lighter 502 lb/in spring. This part is called the air spring. I also had problems with repeated creaky CSUs. I ran the Helm, it was good and fill travel never an issue (82kg). Found inside – Page 29SUSPENSION : Aer Macchi telescopic front fork with hydraulic damping . Pivoted - fork rear springing employing one coil spring and hydraulic damping . That aside the XC 30 is a functional fork that requires little maintenance and is found as a standard component on many off the shelf bikes in the RM2500-RM3500 range.

The XCR features 100mm of plush travel that gobbles up trail chatter and smooths out your ride. The improved traction allows you to corner harder without having to worry as much about your wheel washing out. But its also costly and annoying.

It's easy to tune beginning, mid and end stroke support. Some of my riding bros were experimenting with coil shocks recently and a few had gone all in on coil forks and coil conversions - like the Push ACS3 and the Vorsprung Smashpot. Would custom tuning reduce the weight of the spring needed? This is measured in either pounds per inch or newtons per millimeter. $1,049. Worn-out seals can cause the fork to make some noise as well.

The differences in ride quality were apparent again. Options are also more limited. . Conversely - if you're after a more linear feel on a bike that is a bit on the progressive side, you may want to lean towards a coil sprung shock. What's the difference? WP's complete AER fork (including the brake calliper mount) weighs 7160g, compared with 8650g for WP's new Xplor 48mm coil-sprung fork (which, itself, is between 300g and 600g lighter than its 4CS and open-cartridge predecessors, respectively). But I've found the 450 with near full LSC is still kind of mushy (though not bottoming - it could just be my impression of coils famous plushness).

The spacers typically just screw or snap into place on the inside of the top cap. Forks also have more volume than rear shocks. Coil forks bottom out more easily because they have a linear spring rate. SHOP All Forks & FORK AccESSORIES. 80, 100, 110, 120mm travel. For example, if it takes 500N of force to compress the spring 50mm, it would take 1000N of force to compress the fork 100mm. Near the end of the range, it takes a huge amount of force to further compress the air inside. Cheaper, tighter seals mean it's not as sensitive off the top as Fox step-siblings either. Increasing the pressure makes the suspension stiffer. I replaced the medium coil to a soft coil which was appropriate for my weight and everything about the bike got better. 30 - 40% progressive or whatever it takes to ramp up like an air shock stuffed full of bottom out tokens on most enduro bikes.

This is a mechanism that locks the fork in it’s resting position so it can’t compress or rebound. Seals add friction to the movement of the shock, so a steel coil requires less breakaway force to start moving and is more sensitive over small bumps and imperfections. While 9mm is simple, thru-axles come in several common dimensions. Air forks require more breakaway force than coil forks. You can brake a bit harder as well. After swapping the lighter then the heavier springs around my weight range into my shock I settled on the stiffer spring and the shock damper run wide open.

For cross country or trail bikes, you might only need 100-120mm of travel. Unsurprisingly, air shocks use a pressurized chamber, while coil spring systems use metal springs of either steel, SLS, or titanium. Coil spring: A coil spring uses a metal spring to absorb impact. Sag is the amount your fork compresses under the rider weight (including riding gear) and setting the correct sag is the only way of reaching the optimum air pressure for your riding weight and style. Other than that all that was leading me to change was the greener grass of coils. Air springs have . These holes are called ports.
