Spacing is 127mm. What ya got?
i have a set of trek’s house brand (matrix iso c-II) aero rims laced to a pair of shimano 7 speed rx100 hubs just laying around my garage. i think i even have a 7 speed dura-ace cassette in there somewhere. if you’re interested i can send you pics.
Same deal on an old Trek 430–wheels probably have less than 500 miles on them. PM me if you’re interested.
