• I purchased a PX10 bike and would like to convert it to fixed gear, but I read that these bikes from the 70s use french threading in the BB which makes it difficult to convert. I have very little knowledge of mechanics. Did anyone successfully convert a PX10 to fixed gear? What are the components I need to use?

  • If you have problems finding the correct French BB you could use a threadless BB and bypass the threads , assuming your planning to use a square tapered crankset
