This is a 19" steel cruiser fat bike frame. Purchased from ebay over the winter to build up, but have decided to abort. Frame shipped with some "light" damage to the rear drop outs and hanger - they're out by about 2-4mm. Didnt worry too much about it because the bike was scheduled fo...

Any of the founding fathers of this thread have a splined freehub broached freewheel laying around in their tool boxes before I start hand filing one?

Re: GCinDC's Giant DH Comp

....... but it's also the absolute disgust i've developed for the effect of salt on the bike..... corrosion. never. sleeps. The bane of east coast two wheeling commuters in ice melt (salt), rust belt wintry months. Every night when I get home the bike gets rinsed off. Immediately. Only real solution.

Anyone know of a larger chain ring for this thing? dan, that crankset has a pinned chain ring on it. they are not designed to be replaced, rather thrown out when worn sufficiently. Any square taper crank should do you just fine. Chain line will need to be considered though. Another thing - did I mi...
