Rohloff PM Bone & PM Axleplate
The Rohloff PM Axleplate in combination with the
PM Bone offers an alternative method of ancho-
ring the hub torque to frames with a 135mm,
142mm, 170mm or 177mm spacing.
The PMAxleplate/PM Bone combination is
recommended when mounting a SPEEDHUB in
all frames with an integrated Postmount direct
calliper mount. The threaded holes of the direct
calliper mount will be used to secure the PM Bone.
Three different mounting options are available:
1. Mounting to frames where the Postmount
(PM) direct brake caliper mount is located
on the seat-stay.
2. Mounting to frames where the Postmount
(PM) direct brake caliper mount is located
on the chain-stay.
3. Mounting on frames where an
International Standard (IS) brake caliper
mount is located on the Chainstay.
Neither the PM Bone nor PM axleplate are
authorized or tested for tandem use!
PMdirect 140mm = Not compatible!
PM direct 160mm = 180mm rotor required!
PM direct 180mm = 203mm rotor required!
PM direct 203mm = Not compatible!
Use of the PM Bone/PM axleplate is only
permitted in dropouts where the PM Bone
anchoring point falls behind an imaginary line
drawn through the dropout slot itself. The correct
location of the anchoring point is vital to ensure
the axle cannot lever itself out of the dropout and
thus to avoid potential accidents and injuries!
PM Bone - Mounting preconditions:
The axle area of the Rohloff PM Axleplate
must lie flush against the dropout material.
The axleplate may under no circumstances
collide with weld-beads or proud standing
frame tubes.
Safe use of the PM Bone/PM axleplate is only
possible if these two preconditions are
satisfied.
1. Mounting to frames where the PM
direct brake caliper is located on
the seat-stay.
Mounting Preconditions: 2. Mounting to frames where the
PM direct brake caliper is
located on the chain-stay.

An IS/PM adapter is secured to the IS calliper
mount as usual. The Rohloff PM Bone
(Art.#8555) is then mounted to this and the calli-
per then bolted to the IS/PM adapter through the
PM Bone.
Possible combinations:
IS frame 160mm + IS/PM Adapter 160mm + PM
Bone = 180mm rotor required.
IS frame 180mm + IS/PM Adapter 180mm + PM
Bone = 203mm rotor required.

The PM Bone (Art.#8555) must be mounted
under directly under the disc brake calliper. This
acts an adapter and thus ist use will require the
a larger brake rotor:

ATTENTION
The various different standards & production
tolerances of the Postmount caliper mount will
result in the PM Bone loacting peg resting at
different heights within the PM axleplate fork.
-Frames using a 160mm direct postmount
must result in a gap of min. 0.3mm between
the plate & bone (use spacers if necessary).
-Frames using a 180mm direct postmount
must result in a gap of max. 7mm between
the plate and bone.
Get in touch with Rohloff service should issues
arise when mounting the two PM components.
