Rohloff A12 Spacer – left-hand
The Rohloff A12 Spacer, left-hand (8596) fits a thru-axle Speedhub 500/14 A12 into Shimano E-Thru 12 mm dropouts on the disc brake side, together with the 8592 reduction sleeve.

Why this spacer?
For Shimano E-Thru. Rohloff lists the 8596/8597 spacers for Shimano E-Thru 12 mm frames.
Pairs with 8592. The 8592 reduction sleeve goes through the spacer to reduce the opening to 7 mm for the axle bolt.
Correct fitting. 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?
- Riders with a Shimano E-Thru frame. The left-side spacer for an A12 Speedhub.
- Workshops. A single spare instead of a complete A12 kit.
