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.
