felt bicycle parts
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 Bike drive-train dampers 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 Bike units for complete efficiency.
