I am building up a bike, and I decided to use a sweet square taper dura-ace crankset I've been carrying around for years. I had the LBS remove the bottom bracket, which was a little more modern(I don't have the tools). I'd like them to put in a new BB so I can fool around with different chainring/sprocket combinations, but they insist that they need all of the parts so they can fool around with the chainline, before they'll know what bottom bracket to get.
I get the impression that they want to build up the bike for me, but I just want them to do the BB so it can be my bike. I can tell that I'll want the chainring as close to the BB as possible, but I also have a sweet, huge chainring I'd like to use if it clears. It's a dicey issue. What should I do?
In the interest of full disclosure, this bike has a 3 speed hub. (don't worry, I ride fixed too! Plus, this bike might end up as a singlespeed) I just thought that this forum would be the best to ask chainline quesitons.
