Review on SHIMANO R203P Disc Brake Adaptor by Doug Small

Revainrating 5 out of 5

Works as advertised

Upgrading my Motiv tandem from 160mm to 203mm rims. This part is suitable for mounting type IS on the frame. The adapter is much wider than the one it replaced but fits well with a small gap between it and the new drive. Note: In the case of IS mounts (2 holes parallel to the wheel axles), it must be specified whether the brake is at the front or at the rear

Pros
  • Consistent test results
Cons
  • Minor issues
