ROHLOFF SPEEDHUB A12
Mounting instruction extension to Owners Manual for all A12 SPEEDHUB units
(suitable for 12mm DT Maxle / Syntace X12 / Shimano E-Thru / SRAM UDH 12
thru-axle frames with an O.L.D. measurement of 142mm / 148mm BOOST / 177mm /
197mm)
The Rohloff AG are extremely pleased that you have chosen an A12 SPEEDHUB as your
next bicycle transmission system.
Please be aware that the internal SPEEDHUB transmission, as well as the outer
construction and all torque anchoring apparatus remains identical to that used by all other
SPEEDHUB versions. As such, information on the use, selection and mounting of these
components can be located in the regular Owners Manual.
The single difference between regular SPEEDHUB models and A12 SPEEDHUB models, is
the axle itself. The correct mounting process for these hubs is described/illustrated in the
following paragraphs.
A12 SPEEDHUB models will only be supplied to professional workshops which have
already measured the 12mm thru-axle dropouts with a special measurement kit. This kit is
available on loan from our distributors upon request. Regardless of the actual result figures,
A12 SPEEDHUB units will be supplied with individually selected and/or bespoke finished
reduction sleeves, suitable for the tested frame only.
The A12 dropout measurement test instructions, plus the complete Rohloff
SPEEDHUB 500/14 Owners Manual can be downloaded from:

There are a few vital safety aspects that need to be adhered to alongside the general
safety information located within the Owners Manual. These are:
1) Dropouts of 12mm thru-axle frames into which a SPEEDHUB is destined, may only
be measured by bicycle manufacturers, authorized Rohloff distributors and
professional bicycle retailers/workshops. The initial mounting of an A12 SPEEDHUB
model into that frame, must be completed by the same company who initially tested
the dropouts.
2) Liability:
a. The bicycle manufacturer, authorized Rohloff distributor or professional bicycle
retailer/workshop holds responsibility for the correct dropout measurement.
b. The Rohloff AG is responsible for supplying the correct reduction sleeves and
micro washers according to the dropout measurement test results.
c. The bicycle manufacturer, authorized Rohloff distributor or professional bicycle
retailer/workshop holds responsibility for mounting the A12 SPEEDHUB model
correctly into the 12mm thru-axle dropouts.
