A: Designing a bike suspension system is complicated. We have an entire team of rockstar engineers who focus exclusively on suspension to help give our bikes the ride quality and characteristics that riders experience. The rear shocks that come factory-installed are the shocks that we test and approve for use. Yes, some shocks that are not original equipment will fit on our bikes, but we can't test them all to confirm if they are truly compatible because our awesome team is busy designing the next amazing ride. If you are considering replacing the original rear shock with an aftermarket shock, always check with the shock manufacturer to confirm compatibility with the bike.
Warning: Even if a shock physically fits on a bike frame, it may not be compatible. Any damage to the frame or other parts of the bike that results from the use of an incompatible shock is not covered by our warranty policy.
