Why the Monkey Bone -10?

  • Brake adapter and torque support. The OEM2 axle plate locks into a recess in the Monkey Bone, so the hub torque goes straight into the frame through the brake mount.
  • Offset for XXL hubs. The -10 version is shaped for the wider 190/197 mm fat bike hubs.
  • Long bolts included. Two M6x30 bolts for fat bike frames come in the box.
  • 160 mm rotor. For a post-mount caliper with a 160 mm rotor on an IS2000 frame mount.

Mounting in short

Fix the Monkey Bone to the IS mount (6 Nm), fit the post-mount caliper loosely, install the wheel so the OEM2 axle plate sits fully in the Monkey Bone recess, then align and tighten the caliper (6 Nm).

Who is it for?

  • Fat bike riders with an XXL SPEEDHUB. Frames with an IS2000 brake mount on the seatstay.
  • Builders of XXL SPEEDHUB bikes. The Rohloff-specified part for this combination.

Frequently asked questions

Do I need the -10 or the normal Monkey Bone?

The -10 versions are for XXL hubs (CC 190 mm, A12 197 mm). For hubs from 135 to 177 mm, use the Monkey Bone 160 (8553).

Can I use it with a quick-release (CC) axle?

Yes, but the anchoring point must be behind a line parallel to the dropout slot through the axle. With the A12 thru axle this does not need to be checked.

I want a 180 mm rotor – which part?

The Monkey Bone -10 for 180 mm rotors (8554-10).
