Title: C11G fork yokes
Post by: rolariel on October 29, 2020, 04:35:02 pm

Hello, Does anyone have a set of C11G fork yokes that are off the bike. I am trying to get the following measurements of the steering stem. I need the diameter of the stem and it's overall length, also the length of the threads at the top. If anyone can help I would be grateful. Thanks, Roland.

I Think to stem is larger at the bottom where the bearing fits than the it is at the top ie different internal diameters of the top and bottom bearings
