Comment on LeMond Zurich 650b Conversion by Rob October 16 2013
The Nifty Swifty is the best cheap option IMO, unless you gave room for a 37mm col de la vie.
You could put a 135 in there, but it may be a bit of work. The steel used on the LeMond bikes will be hard to cold set and I would look into finding a 130mm spaced wheel.
