im currently riding with a truvatuv cheap crankset which works fine, but i have a new 105 crankset sitting in my basement because i put dura ace on my road machine. the 105 has outboard bearings and i want to take off all but the 39 tooth chainring and use it on my fixie because i hate seeing such a good crankset go to waste. the problem is, a few reputable bike shops have told me that it cant be done because the outboard bearings will screw with the chainline. but, today, when im buying tires, i come across this http://www.ride-track.com/buy/TruVat...kset/20280005/ ... apparently truvativ now makes an outboard bearing crankset for track. i have the same BB for my 105 as the truvatuv crank on that site uses, so it made me wonder, is it possible to use my 105 on my track frame or are the bike shops right? thanks.
