STFU DH 10 SPEED Mountain Bike Drivetrain Damping Module - Up to 32T Cassette
Developed in collaboration with downhill mountain bike legend, Chris Kovarik in Whistler BC. Designed to keep your bike quiet and efficient whilst minimizing wear.
The STFU drive-train 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.
DH-00 - Single Speed Bikes
Under tension from pedaling the chain remains completely clear of the STFU units for complete efficiency.
We have changed names: now Giant Knox City.
