After watching Neko Mulally's amazing run at the UCI World Cup DH in Hafjell in 2014 and Aaron Gwinn's win in 2015 after both snapping chains near the start gate, the CEO and engineer behind OChain was stunned and set about creating a chainless riding experience where the bike flows, pumps and pops in the absence of pedal kickback.

Despite MTB suspension engineer's best efforts, the tension on the chain between the cassette and chainring affects the performance of the rear suspension, it also has the side effect of fatiguing the rider. When your rear suspension compresses, chain growth is required and because your chain can't grow your cassette tugs your chain backwards resulting in pedal kickback.

The degree to which pedal kickback occurs varies with each bike's suspension design but is present in all MTB rear suspension designs to some degree. Typically there is anywhere from 3° to 15° of backward rotation required by your chainring during suspension compression resulting in pedal kickback. With your weight standing on the pedals this backwards rotation is impeded which has the effect of stiffening your suspension. The more travel you use, the more kickback you'll experience. Pedal kickback occurs during braking as well and is a function of the suspension design and the amount of brake squat or rise, making the suspension even stiffer under braking.

Ochain decouples the chainring from the cranks to allow the chainring to rotate backwards when the chain is pulled by your cassette under suspension compression and/or braking. Each OChain is supplied with a rubber kit to switch between 4°, 6° and 9° compensation which allows you to customise the OChain depending on your travel and riding style, and there is an optional 12° elastomer kit available for DH and Park bikes.

The OChain Integrated is specifically designed for Superboost (157mm rear hub width) applications and integrates the OChain Active MTB Spider with a 56mm chainline Superboost chainring. Please note: These are not compatible with standard Boost drivetrains (52mm chainline and 148mm rear hub spacing).
