Well, put the crank, and drivetrain parts on. New Crank has 175mm arms as opposed to 165mm arms.
Flipped the stem back up, rolled the bars up (towards me), seatpost up, and saddle back a tiny bit. Took Robbie's suggestions, my cousin works at a local Trek dealer as a mechanic, he watched me ride it, and adjusted it like he thought it should be. He was spot on. He said with the way the stem was, how the bars were, and saddle tipped down a little bit that I was transferring all the weight to my hands, which would explain why they started to get a little numb on 50+ mile rides. Haven't had a chance to give it a whirl, but I'm hoping to today after work!
Lost a chainring up front, but now have a nice robust Hollowtech set, with a much nicer BB, and 175mm arms.
We made the Triple Sora shifter work with the double crankset.... I was going to ride to work today, but had no interest in riding in the rain. I did take it around the block last night. I have to say that the 105 parts shift WAY BETTER, than the 2203 FD, and Tiagra RD. Can't wait to actually ride it.
This crankset is MUCH nicer than the Bontrager Sport with the stamped steel rings that came on the bike....can kind of see here:
