Noise

When you hear a noise that seems to be coming from your Powershift hub, there is a number of possible reasons for this. Before you contact support or submit a warranty or service request, please check the possibilities below.

 

Cause Rectification How?
Noise while riding in 0.7 First check if the noise could be coming from other components on the bike: Bottom bracket, spokes, worn out chain, …

Ensure thru axle is tightened to correct torque (10Nm)

Ensure correct spacer set-up (use cone spacer if needed, if using metal spacer ensure there is a plastic spacer assembled at both sides).

Check torque arm friction (if torque arm bolt is metal, request dealer to swap it for a plastic variant).

For bikes with closed drive side dropout (with split threaded end): Apply grease at inside of closed dropout to reduce rubbing of threaded end inside the dropout.

Noise while riding in 1:1 First check if the noise could be coming from other components on the bike: Bottom bracket, spokes, worn-out chain, …
  • Ensure that the thru axle is tightened to the correct torque (10Nm).
  • Ensure a correct spacer setup (use a cone spacer if needed, if using metal spacers, ensure there is a plastic spacer assembled at both sides of the metal spacer).
  • For bikes with a closed drive side dropout (with split threaded end): Apply grease at the inside of the closed dropout to reduce rubbing of threaded end inside the dropout.
Noise in both gears First check if the noise could be coming from other components on the bike: Bottom bracket, spokes, worn out chain, …
  • Ensure that the thru axle is tightened to the correct torque (10Nm).
  • Ensure a correct spacer setup (use a cone spacer if needed, if using metal spacers, ensure there is a plastic spacer assembled at both sides of the metal spacer).
  • For bikes with a closed drive side dropout (with split threaded end): Apply grease at the inside of the closed dropout to reduce rubbing of threaded end inside the dropout.
Noise when freewheeling Check the correct installation of the wheel in the bike.

Check for lateral play.

Make sure the wheel and the hub are correctly installed.

(cassette in notches of the hubshell, plastic shim under cassette, lockrings tightened at 40Nm, correct torque arm installed (no gap (old torque arm on new hub)), disc and centerlock ring correctly installed and tightened, thru axle completely tightened (hand-tight, approx 6-10Nm) regardless of direction of shifter lever, correct thread end installed.

 

Note: You can expect a noise of the ratcheting mechanism, this is a silent humming sound and is normal.

If, after the above checks, there still is another sound: Contact Classified.

Noise when pedaling under heavy load First check if the noise could be coming from other components on the bike: Bottom bracket, spokes, worn out chain, … See 'noise in both gears'
Creacking noise in Open Wide Check the correct spacer set-up.
  • Correct spacer set-up: 
  1. One 5 mm spacer
  2. Two 2 mm spacers
  3. One conical spacer at the end to fit nicely in the dropout
  • Apply grease to the nutlock.
