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

Stfu

by

Didn’t notice much of a difference of chain slap noise only worked when I got it in the absolute perfect position. Also got caught in my spokes a few times and finally gave in after 5 months of riding and ended up not being able to use because it had been stretched and wouldn’t take any impact without going into my spokes

No noticeable difference in noise, broke after few rides

by

Thought I'd try this as I'm a fan of quiet bikes. Pretty easy to install although I was doubtful if would stay in the right spot for long. I honestly couldn't notice any huge difference if chain noise over standard chainstay protector. I was right to doubt it would stay put as it came loose and got pulled into the spokes on a decent. I had to destroy it to remove it so I could keep riding. I wasn't upset. It was a waste of money.

Makes for a quiet drivetrain

Effectively keeps my chain off the frame on the rowdiest of trails.

Works great, definitely worth it.

Just ordered my third STFU, I have one on both my other bikes and definitely recommend it. They work great and are fairly easy to install. It does seem a little expensive for what's basically a chain stay protector but absolutely worth the money. I had it go into the spokes on both of my bikes, once on each. Not sure why it happened, no damage to the bike, one STFU got pretty torn up but still works perfectly once reattached.

Buy the best or STFU

The STFU is the best if not one of the best chain silencers you can buy. This is the second one I have brought for a second bike and both made a huge difference. If you are able to get rid of the other little noises from your bike adding this will make it dead silent. I had to wait for this to come in due to stock shortages but it was worth the wait.

Silenced my drivetrain

Bought these as I was sick of having to often replace to replace the mastic tape I was using. These work really well, zero chainslap or noise and help pretoce the chainstay. Only downside is they do look a little odd, but the silence makes it worth it. Do recommend
