STFU Drivetrain Damping Module Parts

Drift king, Aussie legend, and friend of MTB Direct, Chris Kovarik has been developing a fantastic new way to keep your bike as quiet as can be while increasing the life of your chain.

Who’s this for: Riders looking to keep their rig running quietly. You don’t know just how loud even the best factory chainstay protectors are until you’ve tried one of these.

Construction: Silicone rubber for the DH units and ABS inner with TPU over mould for the TRAIL units.
These have been tested extensively by Kovarik and many others in order to get the best fit for the most bikes, and for different cassette sizes.

Materials: Silicone rubber for the DH units and ABS inner with TPU over mould for the TRAIL units to allow the device to absorb all the sound and energy from the chain slapping into it. STFU takes the hit so your frame doesn’t have to.

Note – comes with 2 pieces that are adjustable to fit most chainstays.
It is advised that 5-6mm wide zip ties are used for the installation. Thinner zip ties will not be as effective.

Pros: Keeps your bike quiet, reduces side to side chain movement, which also reduces wear and prolongs chain life.

Available in an option to suit most bikes:

• DH-10: DH gearing with 10+ speeds, max 32t cassette
• DH-07: DH gearing with 7 speeds, max 26t cassette
• Enduro-Trail: 1x drivetrains with max 52t cassette

Cons: Looks a bit funny
