Surly 10/12 Adapter Washer for QR
This fine pair of Surly 10/12 Adapter Washers is designed to adapt any 135, 170, or 190mm O.L.D. QR axle hub with a 142, 177 or 197mm spaced thru-axle frame.
Make sure the QR axle on your wheel is the right length for the frame spacing. For instance: 190mm OLD QR goes with 197mm thru-axle spacing.
