Rohloff Chain Tensioner jockey wheels
The Rohloff Chain Tensioner jockey wheels (Art. 8251) are one pair of replacement wheels for the Rohloff chain tensioner – the wear part that keeps your SPEEDHUB chain running quietly.
Why fresh jockey wheels?
Wear part. Jockey wheels wear with every kilometre; worn teeth mean noise and a less secure chain.
One pair. Both wheels of the tensioner in one pack.
Quick swap. Remove the cage from the pivot axle, undo the lower jockey wheel bolt, replace the wheels (Rohloff manual).
Quiet drivetrain. A SPEEDHUB chain drive runs on one chainline; worn jockey wheels are a common source of noise.
Who is it for?
- High-mileage tourers. Replace when the teeth look hooked or the drive gets noisy.
- Riders fitting a new chain. A good moment to renew the jockey wheels too.
- Workshops. Standard wear part for SPEEDHUB service.
