i have a 1979 hardtail that the former owner raked out and left the stock forks on well after laying it down twice last year i decided to tear it down and redo it my question is i have found extended fork on here but they are all for early bikes how hard would it be to convert my bike to the 34 mm tubes instead of the 35s? Or should i just quit being a cheap ass and buy new tubes from mikes?
