Rohloff Conversion kit Chain Tensioner
The Rohloff Conversion kit Chain Tensioner (Art. 8248) adapts older Rohloff chain tensioners (built before the end of 2002) to the redesigned, improved torsion spring.
Why convert an old tensioner?
Improved spring. Brings older tensioners up to the modified spring Rohloff has used since the end of 2002.
All parts in the bag. The photo shows the torsion spring, a countersunk bolt with nut, a cone washer and a new safety clip.
Clear procedure. The old jockey wheel bolt is swapped for the new countersunk bolt M4x20 (Torx TX20, 3 Nm) with cone washer.
Keeps an old SPEEDHUB going. Early SPEEDHUB bikes deserve a working tensioner too.
Who is it for?
- Owners of early SPEEDHUB bikes. Tensioners from before the end of 2002.
- Riders whose old spring broke. Convert instead of buying a whole new tensioner.
- Workshops. For vintage SPEEDHUB service.

Frequently asked questions
My tensioner is newer – do I need this kit?
No. Tensioners with the new-type spring need only the spring 8705.
Can I reuse the old safety clip?
No – Rohloff says not to reuse it; the kit includes a new one.
Does it change the jockey wheels?
No. Only the lower jockey wheel bolt is replaced by the new countersunk bolt.
About Rohloff
Rohloff AG from Fuldatal near Kassel, Germany, builds the SPEEDHUB 500/14: a 14-speed gear hub with evenly spaced gears, a 526% gear range and a sealed oil bath. As robust as the hub is, Rohloff sells small wear and replacement parts individually, so a SPEEDHUB is repaired, not replaced.
BoodaBike (Massive Bikes, Budapest) is an official Rohloff service centre, trained by Rohloff, and an official European distributor of Rohloff hubs and parts. We sell genuine Rohloff parts and we are happy to help you identify the right one for your hub version.
