So, my dream project (my dad's bike) has come with a weird twist. The headset was completely rigged with parts from 2 complete headsets (think 1 jammed in the other). Anyways, I took out all the crap and I realize that the fork is ISO but the head tube is JIS. Has anyone ever successfully mixed an ISO fork with a JIS headtube, and how did you do it and did it last. I'm guessing that there's some fix to this issue, but I can't place my finger on it. I guess I would buy two tange headsets and use the JIS half on top and the ISO half on the bottom, but I hate being this ghetto. Whaddaya think?
I'd like to buy a used JIS fork, but there's another issue that the steerer itself has to accomadate the 4 5/8" head tube length. Any ideas where to buy a JIS fork?
