I am going to be building up a new road bike on the cheap in the not too distant future and can get a great deal on a Shimano UN73 sealed bottom bracket with a standard square taper. Two questions:
- Is this a decent bottom bracket? I know it's not the lightest at 289 grams, but the price is right for $13 brand new. I'm just looking for a good quality middle range bracket, and can upgrade to lighter/better later when finances permit. I don't care about bling, anyway you can pretty much tell any lie you want about a bottom bracket once it's in the frame .
- The two spindle lengths that are available are 115 and 122.5, I don't have a clue as far as what cranksets these lengths are proper for, any insights?
TIA for the help, opinions, harassment, etc....
