Chain roller

Chain roller

The chain roller guides the chain below the seat to the rear wheel and is an essential part of the HP VELOTECHNIK No Squat design. It ensures that no pedaling influences get into the suspension.

The surface of the chain roller features a „si- lent ring“ that is made of a long lasting elasto- mer. Depending on maintenance and care it has a life span of approx. 3000-5000 km.When this section is worn completely the links of the chain will run on the roller. In that case you will notice that the chain makes more noise while running and you should change the rol- ler.

The chain roller consists of two parts.After you have dismounted the chain roller you can tear the two halves apart and change the silent ring.

Dismounting the chain roller

Hold the nut on the left side of the frame with a ring spanner SW 13 and undo the screw in the chain roller with an Allen key SW 8.

Memorize the exact position of the washers. Remove the screw together with the chain roller from the frame. Change the chain roller. Lubricate the shaft of the screw..

Push the screw through the chain roller, the washer and the spacer with the retention spring into the frame. Put on the washer on the left side, secure the thread with LOCTITE and tighten the nut with 14-16 Nm.

Caution! The roller comes with two maintenance free sealed bearings.The bearings are exchangeable. Between the bearings there is a spacer that keeps the correct distan- ce. If you forget to put in the spacer after you have dismounted the bearings they will be destroyed when you tighten the screw while remounting them.

The bearings must not be treated with a jet of water from a high-pressure cleaner or with solvents since it destroys the seals and removes grease in the bearings. If the bearings don't move smoothly anymore you'll have to replace them.
