Rohloff Chain Tensioner arm
The Rohloff Chain Tensioner arm (Art. 8249) is the replacement arm for the Rohloff Chain Tensioner 8250, 8250-10 and 8250-15 – fix a bent or damaged tensioner instead of buying a new one.
Why replace only the arm?
Repair, don’t replace. A bent arm after a rock strike or crash does not mean the whole tensioner is lost.
Fits three versions. Listed by Rohloff for 8250, 8250-10 and 8250-15.
Restores the chainline. A straight arm keeps the jockey wheels in line and the chain running quietly.
Workshop-friendly. Reuse your jockey wheels, spring and bolts.
Who is it for?
- Riders with a bent tensioner. Off-road knocks are the usual cause.
- Long-distance tourers. A light spare that saves the trip.
- Workshops. Repair customer tensioners economically.
