Thank you for purchasing a Monkey Bone rear disc brake
adapter. The Monkey Bone offers a simple method of
anchoring the axle of the Rohloff SPEEDHUB 500/14 to a
frame through the disc brake mount. In order to use the
Monkey Bone, your SPEEDHUB 500/14 will need an
OEM2 axle plate, your frame must have an International
Standard disc brake interface, and your disc brake caliper
must have a Postmount interface. The Monkey Bone is
not compatible with IS direct-mount disc brake calipers
or frames with Postmount disc brake interface.
Required Tools:
•
5mm Allen wrench
•
Torque wrench
•
T20 Torx wrench
Required Parts:
•
Frame with IS51 disc mount interface
•
Disc brake caliper with Postmount interface
•
Rohloff SPEEDHUB 500/15 with OEM2 axle plate
•
Monkey Bone
•
2x M6x16 bolts (sold separately; typically
included with disc brake caliper)
•
2x M6x18-20 bolts (sold separately; often

Installation Instructions
1.
Ensure that you have the Monkey Bone that is appropriate
for your disc rotor diameter (160mm or 180mm; 203mm
rotors can be used with 180mm Monkey Bone and spacers
(sold separately))
2.
Attach the Monkey Bone to the frame using two M6x18-20
bolts. Ensure that slot for OEM2 axle plate faces the
dropout. Tighten bolts to a torque of 6 N-m/51 in-lbs.
3.
Connect disc brake caliper to Monkey Bone using two
M6x16 bolts. Leave bolts loose enough that caliper can
slide side to side.
4.
Install wheel into dropout taking care to align slot in end of
OEM2 axle plate with cutout in Monkey Bone and disc rotor
between brake pads.
5.
Check position of EX shift arm with OEM2 axle plate
engaged with slot in Monkey Bone; reposition axle plate as
needed for desired cable routing using T20 Torx wrench
(see Rohloff owners manual). Tighten axle plate screws to a
torque of 3N-m/25 in-lbs.
6.
Fully seat axle in dropout before tightening quick-release
lever or axle nuts. Threaded axle nut torque: 35 N-m/310
in-lbs; Pitlock or bolt-on skewer torque: 7 N-m/60 in-lbs.
7.
Follow brake manufacturer's recommendation for setting
brake caliper position. Tighten brake caliper bolts to a
torque of 6 N-m/51 in-lbs.
CAUTION:
Use of the Monkey Bone with some frame geometry can result in the
wheel being pulled out of the dropout while pedalling due to the
forces exerted by the Rohloff SPEEDHUB 500/14 onto the frame.
When the anchoring point of the OEM2 axle plate is located in front
of a line parallel to the dropout slot, there is a component of the
reaction force in the lowest gears that tends to push the axle down
and out of the slot. Per Rohloff's recommendation, the Monkey
Bone and OEM2 axle plate combination are not recommended for
use on frames with such geometry (see page 30 of the Rohloff
owner's manual for more info).
Use of the Monkey Bone and OEM2 axle plate is entirely at the user's
own risk. The forces applied to the disc brake mount by the Rohloff
SPEEDHUB 500/14 can damage some frames. Please contact your
frame manufacturer to determine whether this setup is appropriate
for your frame and whether it affects your frame warranty
