Bikers are meticulous. Any noise on the bike, no matter how quiet, can spoil the tour. With these tips, you can eliminate the most common sources of noise on your bike and glide along the trail almost silently.

1 Vibrating trains

Foam

To prevent internal cables from rattling, they should be laid in foam sleeves. These sleeves are available from Capgo, for example. Two metres of them weigh just three grams.

Bottle brush

If you want to ensure peace and quiet for your internal cables later on, fix them in place with a twisted bottle brush. They can also be pushed through the head tube or bottom bracket into the down tube if the cables are already fitted.

2 Beating chain

Slapper Tape

The self-adhesive tape made of profiled elastomer is not only the perfect solution to prevent paint damage to the rear triangle, but also dampens chain slap on rough terrain.

Downhill legend Chris Kovarik has invented a new part to prevent chain slap. The two rings of the STFU guide are designed to reliably tame and immobilise the chain.

3 Rattling cables

Self-sealing tape

Alternative to cable ties: self-sealing repair tape from the DIY store. It fixes the cables permanently and rattle-free.

Line clips

With the swivelling S-hooks (e.g. from Jagwire), individual cable segments can be clipped together. This prevents noise and also looks neat and tidy.

4 Creaking drive

Freewheel body

Too little grease on the freehub body is a common cause of cracking and creaking noises when pedalling. So remove the cassette, clean the freehub body and apply plenty of thick grease.

Chainring

Sometimes the fit of the chainring on the crank also causes noise. The same applies here: first clean thoroughly and then coat with assembly grease.
