Rohloff Speedhub 500/14 TS DB XL OEM2 – 170 mm, 32-hole
The Rohloff Speedhub 500/14 TS DB OEM2 XL (170 mm O.L.D.) is the 14-speed gear hub with a bolt-on threaded axle, disc brake hub cap and OEM2 axle plate – for frames with an IS2000 disc brake mount and wide 170 mm rear spacing. 14 evenly spaced gears, a 526% range and a sealed oil bath give you a drivetrain that works with a chain or a Gates belt and needs little more than a yearly oil change.
Why the Speedhub 500/14 TS DB OEM2 XL?
Fourteen even gears. Rohloff spaces the 14 gears evenly, about 13.6% apart, across a 526% total range – steep loaded climbs and quick flat stretches with one shifter. 
Gears in oil, out of the dirt. Rain, mud and dust stay outside: the gearbox of the TS DB OEM2 XL runs in an oil bath behind seals. Service is an oil change every 5000 km or once a year. 
Belt or chain. With a single rear sprocket the TS DB OEM2 XL runs a chain or a Gates Carbon Drive belt; for the belt, Rohloff prescribes the lock-ring splined carrier (8540L or 8540SL). 
Torque support on the brake mount. The OEM2 axle plate anchors the hub torque on the rearmost hole of an IS2000 brake mount. With a disc brake it is combined with a SPEEDBONE or Monkey Bone. 
DB hub cap for disc brakes. Disc brakes mount on a special Rohloff 4-hole rotor (Ø160–220 mm, for 1.8, 2.0 and 2.3 mm brake systems). Rotor screws are in the box; the rotor itself is ordered to suit your brake. 
One shifter, no front mech. All 14 gears sit on one twist shifter with two cables – no front derailleur, no chain jumping between rings. Shift while rolling or standing; ease off the pedals as you do.
Solid threaded axle
The TS hub has a solid M10x1 threaded axle and is fixed with axle nuts (15 mm wrench). This version combines the bolt-on axle with the OEM2 axle plate: anchors the output torque of the hub to the rearmost mounting hole of an IS2000 disc brake mount.
Rohloff supplies TS and OEM versions without a chain tensioner; add one (8250) if your frame has no chain tensioning of its own.
Wide 170 mm rear spacing
Rohloff builds the TS DB OEM2 XL with the same kit contents as the 135 mm TS DB OEM2 version, but with a 170 mm O.L.D. for wide rear ends – only in black, with 32 spoke holes and a disc brake hub cap.
For service, the XL hub uses its own axle-plate screws (8236XL) and paper gaskets (8714XL); the sprocket remover tool is the standard 8508.
Speedhub and Gates – our daily work
Massive Bikes started in Budapest in 2013 with Gates belt and gear hub conversions – today our BoodaBike Pulse touring bike rolls on a belt and a Rohloff Speedhub.
For a Carbon Drive sprocket Rohloff specifies the lock-ring splined carrier (8540L for the standard or 8540SL for the slim chainline); the 16-tooth sprocket in the kit is for chain use. Tell us your frame and we help you pick the carrier and sprocket.
Who is it for?
- Long-distance tourers. A sealed hub with no exposed gears keeps working through rain, mud and dust, far from the next bike shop.
- Riders who prefer a bolt-on axle. The solid threaded TS axle is clamped with axle nuts – a firm, simple wheel mount.
- Fat-bike and wide-tyre builders. The 170 mm O.L.D. matches wide rear ends; this version is made in black with 32 spoke holes.
- Riders who value comfort. Shifting at a standstill and one simple twist shifter make every ride relaxed – useful in town and on long climbs.

Frequently asked questions
What else do I need for the OEM2 axle plate?
With a disc brake the OEM2 plate is used together with a SPEEDBONE (8550) or a Monkey Bone (8553 for 160 mm, 8554 for 180 mm rotors). Rohloff also notes that the frame manufacturer must approve torque support on the brake mount; otherwise it is at the rider's own risk. These parts are sold separately in our shop.
Can I use it with a Gates belt drive?
Yes, in a belt-ready frame. Rohloff specifies the lock-ring splined carrier (8540L standard or 8540SL slim chainline) for Carbon Drive sprockets. We build belt-drive Rohloff bikes ourselves and supply the matching parts.
Why is the XL hub only in black and 32-hole?
Rohloff makes the 170 mm XL hubs only as 32-hole disc-brake versions in black. For service use sprocket remover tool 8508, and the XL/XXL axle-plate screws (8236XL) when changing the axle plate.
How much maintenance does it need?
An oil change every 5000 km or once a year. Rohloff notes the hub keeps working even if some oil is lost, but delaying the oil change can damage the gears. The warranty is two years from purchase; wear parts such as seals, sprockets, shifter grip rubber and rotors are excluded.
Can it go on a tandem or cargo bike?
Rohloff approves the Speedhub 500/14 for tandem and cargo use in dedicated versions (article suffix T or C), with a maximum input torque of 130 Nm at the hub sprocket. This listing is the standard version – ask us for the T or C version.
