Disc I need more threading, chain line issues
Hi Guys, here is concise breakdown
I am using a road TT frame for track pursuit event. I have a Zipp 900 rear disc with a long track axel so it fits the 130mm horizontal drop outs of the TT bike.
However, my problem is that the threading on the axel for the Cog is shallow, as a result the chain line is off a bit. Is there an adapter that can screw on to the existing threading to extend it. If I can just get a little more threading to move the Cog to the right, it will line up perfectly.
Thanks
