Please read carefully before ordering
Speedco Disc Brake Adapters are CNC machined from 6061 aluminum by Rennen Design Group in the USA. These adapters are intended to be used with a size 120mm disc, and we recommend a Shimano XTR hydraulic caliper for best braking performance.
We offer 6 different sizes / axle configurations to go with our frames. It's very important that you order the right adapter for your frame. If you have an M2 Pro frame and order a Velox Pro adapter, or vice versa, you're going to have issues. There is a 1mm tolerance difference in the center of the drop-out on these frames, so please order appropriately.
Both the Velox youth and the M2 youth sizes share the same adapter.
