Rohloff A12 Reduction Sleeve – right-hand, M12x1.75 Threaded
The Rohloff A12 Reduction Sleeve, right-hand, M12x1.75 threaded (8593) is the sprocket-side sleeve for DT Swiss / Maxle thru-axle frames with M12x1.75 thread, adapting them to the 7 mm axle bolt of the Speedhub 500/14 A12.
Why the original sleeve?
12 mm to 7 mm. A12 reduction sleeves reduce the 12 mm thru-axle opening to 7 mm for the M7x1 Rohloff axle bolts. 
Coarse-thread version. For frames whose sprocket-side dropout has the coarser M12x1.75 thread; tightened with a 13 mm spanner to 10 Nm. 
Measured, not guessed. Rohloff states that 12 mm thru-axle frames must be measured with the A12 dropout measurement kit (Art. 8600) to work out which reduction sleeves and spacers are needed.
Who is it for?
- DT Swiss / Maxle frames with M12x1.75 thread. The sprocket-side sleeve for an A12 Speedhub.
- Workshops fitting A12 hubs. Keep the correct pitch at hand for Maxle-type frames.

Frequently asked questions
Can I use the M12x1.5 sleeve instead?
No. The sleeve must match the frame thread exactly; M12x1.75 and M12x1.5 are not interchangeable.
Do I need a sleeve on the left side too?
Yes – on DT/Maxle frames the left side uses the reduction sleeve 8592.
About Rohloff
Rohloff AG is a German manufacturer from the Kassel area, best known for the Speedhub 500/14 – a sealed 14-speed gear hub with evenly spaced gears. Rohloff sells every spare part as an individual item, so a Speedhub can be serviced and adapted to a new frame instead of being replaced.
BoodaBike (Massive Bikes, Budapest) is an official Rohloff service centre, trained by Rohloff, and an official European distributor of Rohloff hubs and parts. We build Speedhub bikes with Gates belt drive ourselves – if you are unsure which part fits your hub or frame, ask us before ordering.
