The Speedco Velox Pro Disc Brake Mounting Kit V2 10mm is an updated version with the upgrades focused on a beefier design to reduce movement around the pivot point of the axle when applying the brake. This disc mounting kit allows you to convert your Speedco Velox frame to accept a disc brake using a 120mm rotor. Available for 10mm, 15mm and 20mm axle configurations. 

Note: These mounts are machined to very tight tolerances and as such, choose the right mount for your Speedco frame as there is a 1mm difference in the center of the drop-out on these frames
