Model designations

A SPEEDHUB’s model name tells you its axle, shift actuation and axle plate — for example SPEEDHUB 500/14 CC DB OEM2 black. Which versions exist is shown in Variants.

The axle

Code	Meaning	What it is for
CC	hollow quick-release axle	vertical dropouts only; quick, tool-free wheel removal
TS	threaded axle with M10×1 nuts	required for horizontal dropouts, fine for vertical ones too; on downhill bikes the solid bolted joint also stiffens the rear triangle
A12	axle with M7 bolts and adapter sleeves	for 12 mm thru-axle frames; the sleeves match the frame’s axle system, so it has to be measured first with the 8600 check kit

The suffixes

Code	Meaning
EX	external actuation: the cables run straight to the cable box on the shift housing, no separate cable stop needed — ideal for short (say 20”) or unusual rear triangles
DB	disc brake cover, always with external actuation
OEM	axle plate for Rohloff OEM dropouts: the support block sits in the left dropout’s extended slot and replaces the long torque arm
OEM2	axle plate for IS disc-mount frames: the brake mount’s tabs also act as the torque support — a clean, tidy solution
PM	axle plate for direct post-mount frames, with the PM Bone adapter
T	tandem: with 2.5 m cables and housings, for tandems and recumbents
XL	for 170 and 177 mm frames (fatbikes) — DB only, black, 32 holes
XXL	for 190 and 197 mm frames (fatbikes) — DB only, black, 32 holes

With no EX or DB in the name, the hub has internal actuation: it needs a cable stop on the frame at least 240 mm from the rear axle, and cannot be combined with a disc brake — see Cables with internal actuation.

OEM versions on a rigid frame need sliding Rohloff OEM dropouts or an eccentric bottom bracket, otherwise a chain tensioner. For how the torque is taken, see Torque support.

Colours and hole count

Every type comes in three colours: silver anodised (polished aluminium until October 2013), red anodised (red powder coat until spring 2008) and black anodised. 32 holes is standard; for the 36-hole version a “6” is put in front of the article number. Flange rings now come factory-fitted on every type.

The disc brake (DB) version

A disc brake needs an IS (1999) or direct post-mount brake mount on the frame. The DB versions have two special features:

1. The cover has a flange for the disc. Because of the large shell bearings and the shaft seal, a standard six-bolt disc does not fit, so the SPEEDHUB uses its own four-bolt Rohloff disc, with four M8×0.75 bolts on a 65 mm bolt circle — see Brake disc: fitting and replacing.
2. Every DB version has external actuation, so the cables never touch the disc in any fitting position.

Any SPEEDHUB can be converted to a DB version later, but only the Rohloff factory service does it — we handle it for you.

Models and article numbers

Article numbers and scope of delivery for the 135 mm CC and TS models. Every box contains the hub, the twist shifter and the cables; the flange rings are factory-fitted.

What to check when ordering

The hub needs the accessories that suit the frame. Go through:

• a chain tensioner if the chain cannot be tensioned otherwise, plus a chain guide;
• SPEEDBONE, Monkey Bone or PM Bone for a disc-brake frame;
• spokes of the right length and the Rohloff disc that suits your brake;
• a straight cable stop for internal actuation;
• a long chain tensioner bolt for a 13-tooth sprocket;
• the TS long axle plate if a trailer hitch, Pitlock or kickstand mounts directly on the axle.

We go through this list during the check.

Special uses

• Tandems: every SPEEDHUB suits a tandem, and since 2021 every dropout width is officially approved. The tandem version comes with 2.5 m cables; we recommend 2.0/1.8/2.0 mm DD spokes with a 2.9 mm bend length. On wheel stiffness: Wheel stability.
• Small wheels: not below 18” — the high flange would make the spokes meet the rim at too steep an angle. Wheels under 26” are laced one-cross only, never radially.
• Half steps: with two chainrings about 7% apart (39 and 42 teeth, say) the 13.6% steps can be halved — interesting for road racing.
• Wider range: two chainrings add one gear (about 13% tooth difference) or two (about 29%); with 50/39 rings the range is 675%.
• Frame-mounted gearbox: with the SPEEDHUB in the frame as an intermediate gearbox, the same minimum chain ratios apply from crank to gearbox; the chain after it is unrestricted.
• Carbon handlebars: the old 8200 twist shifter is not approved on carbon bars; the 8206 and 8207 are.
• Quick release: use only a steel-axle quick release on a CC axle; light alloy or titanium-axle quick releases are at your own risk.
