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.

"I've been running the Trail model of the STFU Chain Damper since the first production run. Following the directions provided, it mounts easily and does what it's tasked with no quibbles. If I take it off, I'm quickly reminded of how the STFU cuts down noise. But most interesting was that it wasn’t just the sounds from the chain connecting with the supplied chainstay protection.
The STFU’s restriction on the chain made the bike feel better, cutting down on feedback through the drivetrain when rumbling down a rough trail. With the chain not able to sling around as much, everything feels tighter, similar to running a fresh chain verse a flogged one.
The STFU chain damper does what it says on the box... riders keen to silence their drivetrain will appreciate it."
