I think the brake blocks are the issue with mine. Might need to scuff them up somewhat. Or change them for something with a better compound.
Or use the bike more.....
that thing is very nice!..if the front wheel dish is off just go spoke to spoke...turning one clockwise 1/4 turn, the next counterclockwise 1/4 turn..until you do the entire wheel..repeat as required and the rim will nudge over..
any chance you could swap for a 94-96ish stem? it bugs me!
