Hello All,

I’ve an old frame that I’d like to convert to 584/650b. The frame is currently set-up with cantilever bosses for 622/700 wheels. I would like to remove these bosses (front and back) and replace them with new ones, in the appropriate location for 584/650b wheels.

Any advice (especially on the safety) on carrying out such a procedure would be much appreciated.

Many thanks in advance.

Best,
Sam
