STFU Bike MTB DH-10 Drivetrain Chain Damping Modules - Downhill - 8- to 12-speed

Developed in collaboration with Downhill legend Chris "Karver" Kovarik

For many years, Chris has put his bikes and equipment to the test and continues to do so. After many years of fine tuning his machines, he began to search for ways to eliminate noise. After 7 years of experimenting with zip ties, hook-and-loop fasteners, strips of rubber, PVC piping, rubber O-rings and other materials he could find, the idea for our STFU devices was born.

STFU Bike Damping Modules

Silent Technology for your chain

The complete range of STFU drivetrain damping devices is designed to keep your bike running quiet and efficient while minimizing wear. The STFU units contain your chain when things get rough – preventing chain slap and noise from your frame but also preventing your chain from over-extending sideways – decreasing wear and extending chain life. Under tension from pedaling the chain remains completely clear of the STFU units for complete efficiency. Thanks to their trimmable length, the modules fit the most bike's chain stays.

The modules of the DH-10 version are designed around 10-speed Shimano style Downhill drivetrains with a maximum sprocket size for the cassette of up to a 32 teeth. Compatible with 8- to 12-speed drivetrain systems. An optimal durometer rubber guarantees maximum sound damping and durability. On selected bikes, this unit works as a single as well (see manual).
