Well, kind of. On the wheelset page at Sheldon's site (this one ) if you scroll down to where the list of wheels begins, he says that all the wheelsets listed will carry a 42mm chainline unless otherwise noted...could be out of date??

And then on the crank page they have the RDs listed as carrying a 42mm chainline as well ( this link , scroll down a bit to the RDs ). I figure that with the 103mm BB, the RDs, and the Formula hubs, I have to be pretty close to 42mm --hopefully not all the way out to 45...then again I'm sure that I'm perfectly capable of doing a poor job assembling everything 3mm out-of-whack.

I'm gonna swing by the LBS tonight on the way home and see about a couple things (I need to learn a little more about bullhorn HB width sizing vs drops, gonna ask them if the Shimano pedals with SPD one side and platforms the other are any good, and a few other things) maybe they can take a look at the chainline while its there.
