SPEEDHUB 500/14 - Koga Signature

Frame types for OEM mounting
Rigid frames with Rohloff OEM dropouts are specially designed for the mounting of all Rohloff SPEEDHUB
500/14 OEM versions. The long slot in the left hand dropout holds the support block of the OEM axle plate.
F
Frame types ( F) have adjustable Rohloff OEM dropouts. With these dropouts on a hardtail frame, the need for a chain
tensioner is eliminated because the wheel (once secured into the dropout inserts) can be pulled backwards to tension
the chain. The dropout inserts are available from a variety of manufacturers with or without disc brake mounts and are
all interchangable (supply information is available under www.rohloff.de). All Rohloff SPEEDHUB 500/14 OEM
versions are suitable for these frame types.
G
Frame types ( G) have unadjustable Rohloff OEM dropout and are specially designed for rear suspension models. A
chain tensioner must be mounted, because the distance between the chainring and sprocket varies as the rear
suspension is activated.All Rohloff SPEEDHUB 500/14 OEM versions are suitable for these frame types.
ATTENTION
All versions mounted to frame types G must be used in conjunction with a chain tensioner (Art.No. 8250) except
when an eccentric BB is being used.Achain tensioner should be ordered with the initial product as it is not to be found
in the regular OEM package.
ATTENTION
No matter what shape the left-hand dropout is, a surface of 40mm diameter around the center of the axle must be flat
to allow the axle plate to sit firmly and evenly againt the inner side of the left-hand dropout. This area is shown in the
diagram below.

Mounting necessities OEM2
ATTENTION
For safe OEM2 mounting with the support bolt or the Rohloff SPEEDBONE, the following points must be well noted:
The disc brake mounts must be one piece with the dropout itself, be of international standard (IS2000) and have the
following minimum dimension requirements:
The minimum thickness of material used must not be less than 6mm.

Ø6.2 mm
Requiremental for the OEM2 mouting of the Rohloff SPEEDHUB 500/14 with a support bolt is the position of the
disc brake mounts. When the mount hole nearest the axle is behind a vertical line C up from the axle center (diagram
1), then the support bolt can be used. When the hole is in front of the vertical line C (diagram 2), then the use of the
support bolt is not permitted.

When permission has not been granted by the frame manufacturer to mount the Rohloff SPEEDBONE or the support
bolt through the disc brake mount, then mounting of the OEM2 versions is at your own risk.
When mounting the disc brake Gustav M. from Magura with a 160/190mm brake disc, the Rohloff SPEEDBONE
Gustav M. (Art.N° 8551) must be used as the brake cylinder is a different shape and, therefore, will not work with the
standard Rohloff SPEEDBONE.
Not possible combinations until 2007:
- Magura Disc Brakes with a Quickmount adapter (160mm discs) and OEM2Axle plate.
- Magura Disc Brakes with theAdapter 16 for 180mm brake discs.
