STFU Bikes - MTB Drivetrain Damping Modules by Chris "Karver" Kovarik

The STFU modules were developed in cooperation with downhill legend Chris "Karver" Kovarik. They reliably prevent chain slap as well as lateral overstretching of the chain and thus ensure that your bike runs smoothly and efficiently anytime. Distracting noises on demanding downhill trails are now a thing of the past.
