Product info
About This Product
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.
