grantham Posted November 17, 2007 Report Share Posted November 17, 2007 (edited) Does anyone know the tollerances that the threads for the fitting of front freewheels/sprockets onto cranks are I know the thread size is 1.37" x 24 TPI just wondering if anyone knew the tollerances in manufacturing?i'm guessing that there made to a high tollernace otherwise there would be slipping/ threading?

psycholist Posted November 17, 2007 Report Share Posted November 17, 2007 1.37" x 24 TPI is the standard for the threading in the BB shell of the frame. I'm not sure if the threads for a screw on freewheel are the same. Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted November 17, 2007 Report Share Posted November 17, 2007 Threads don't get toleranced. 1.37" x 24 tpi is what it is. The die used for tapping that thread is as accurate as the tool makers make it, end of story.Dave Quote Link to comment Share on other sites More sharing options...
