The Speedco Velox Disc Brake Mounts are CNC machined out of 6061 aluminum. These mounts are available in 10mm, 15mm and 20mm, and replace your Velox Pro Frames non-drive side inner axle block. They are compatible with a size 120mm disc rotor, and will not work with a 140mm disc rotor. For optimal braking performance, we always recommend a Shimano XT/XTR hydraulic braking system.

Sold separately.
