Rohloff DH Chain Tensioner – Shorty
The Rohloff DH Chain Tensioner Shorty (Art. 8245) is the compact chain tensioner for downhill and extreme off-road SPEEDHUB bikes with a standard derailleur hanger.
Why the DH Shorty?
Short and tucked in. A short arm keeps the tensioner higher and out of the way of rocks and roots.
Derailleur hanger mount. Bolts to the standard derailleur hanger like the standard Rohloff tensioner.
Made for SPEEDHUB. Rohloff recommends it for downhill riders and extreme off-road athletes.
Serviceable. Replacement arm 8246 is available separately.
Who is it for?
- Downhill and enduro riders. Where a long tensioner arm would take hits.
- Off-road bikepackers. Rough tracks with a SPEEDHUB.
- Full-suspension owners. When the frame needs a tensioner but ground clearance matters.

About Rohloff

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.
