just got done ordering all my SS stuff for the trek 3700...because I was just so sick of the crappie shifting with low end shimano stuff. just didn't cut it anymore, so, heres what I got, (new grips, levers, SS chain (KMC), bestsinglespeedbike.com conversion kit cog,spacers, and tensioner, salsa 36t silver chainring w/prob solvers 6mm bolts. also an old school square taper shimano deore 5arm crank with 110bcd ...I'm hoping the bike will be over all much better, but here's my question I really hope mine is a freehub and not a threaded freewheel? freehub is the kind that says "lock ring type" on the biggest cassette cog right?
