Rohloff SPEEDHUB 500/14 with a disc brake
The mounting of the
with the use of a disc brake requires a frame with disc brake mounts
of international standard (IS1999). The hubs are available with the choice of axle, quick release (CC DB versions) or
threaded axle (TS DB versions). The particulars of the DB versions are:
The hub cap includes a center disc mount. It is on this side that the external gear mech is also to be found. Normal 6-
bolt brake discs of international standard are not mountable, a special 4-bolt
disc with only four securing
holes for bolts M8 0.75 must be fitted due to the large diameter of the hub seal.
offers a range of discs from
160mm to 203mm for nearly every type of disc brake currently on the market. More details are to be found on the
web under www.rohloff.de > FAQ > SPEEDHUB > disc brake
The disc brake versions of the
are only available with the external gear mech, because
the brake disc/caliper could interfere with the hub cables of the internal gear mech.
The interchangable parts system allows the conversion of any
to a disc brake version
(DB versions). The conversion of a hub to a DB version can only be carried out by the Rohloff service department.

Advantages of the separate options
OEM2 axle plate uses the disc brake mounts to secure the torque of
the hub. Therefore, permission must be obtained from the frame manufacturer to ensure that the guarantee is not
affected.
Threaded axle TS
Quick release axle CC
The
versions with a threaded axle are required for frames with horizontal dropout
slots. It is, however, also possible to mount this hub in dropouts with vertical slots. For downhill riders the
possibility of using a more secure TS threaded axle will increase rear wheel stability much like a thru axle.
Rohloff SPEEDHUB 500/14
The
versions with quick release axles are exclusively for use on frames with vertical
dropout slots. They allow for a quick removal/installation of the wheel without the need for tools.
The internal gear mech is on all
versions with the exception of EX and DB models.
It requires a minimum distance of 240mm between the axle and the cable guide mounting point. To prevent the
possibility of the bayonet connectors coming into contact with the brake disc, a combination of disc brake and
internal gear mech is not available. The internal gear mech model is the lightest of the two gear mech versions
with the
CC weighing approx. 1700g.
The models with an external gear mech allow the shifter cables to run uninterrupted from the twist shifter to the
cable box, so the need for a separate cable stop is also eliminated. Because of this, the external gear mech is
especially useful for frames with a short chainstay length (20" wheels) or uncommon rear triangles.
The external gear mech is approx. 100g heavier than the internal gear mech, but, therefore, more robust as no
separate hub cables are in use. In the case that the shift cable should break, this system allows the user to select
any gear from the outside of the external transfer box making this especially useful for the everyday and the
touring rider.
The disc brake versions (DB) of the
are equipped with the external gear mech as the
hub cables of the internal gear mech would come into contact with the brake disc.
The
OEM versions require the use of
OEM dropouts where the left hand
dropout slot is long enough to house the support block of the OEM axle plate which replaces the long torque arm.
On hard tail frames with adjustable
OEM dropouts, the need for a chain tensioner and chain guide is
eliminated, therefore, the system looks cleaner, tidier and also has a higher level of functional safety, ideal for
extreme riding situations.
With the OEM2 mounting the disc brake mounting holes in the frame are used to prevent the axle from turning
(torque securing). The OEM2 axle plate replaces the long torque arm and gives a cleaner and tidier look to the
system. However, a disc brake mount of international standard (IS 1999) needs to be used under consideration of
the mounting requirements. Through simply replacing the axle plate every version of the
can be converted to OEM2 usage. An
