The short version: I like it a lot!
The longer version: My previous road bike was an '86 Peugeot Triatholon, what a difference 20 years of technology makes I *love* not having to reach down everytime I want to shift and (surprise, surprise) find myself shifting more often, the closer gears are also a lot nicer. It's a steel frame so no surprises there, very comfortable & stable, yet nimble. I did swap the Bontrager stem for an Easton that had a slightly lower rise and that's working out better for me. I can ride on the hoods and not be too stretched out. The Bontrager saddle was also ditched and replaced w/ a Concor light, so far, so good. The 105 components work just fine, Ultegra would have been nice, but probably overkill for me. The Cane Creek brakes are OK, but the pads are junk, Kool Stops will be on soon. So far I'm liking the 175 crank arms, but we'll see. I've been riding the Bontrager tires, but I have a set of Vredesteins on order. I went out for 10 miles this morning and it may be my imagination, but the bike does feel faster. The Peugeot ways about the same & the wheels are comparable as well so who knows. The riding position is a little bit more upright than the Peugeot and it makes a world of difference, no aching back and my boys didn't go numb either! It really felt good riding this morning, I had forgotten just how much I do love being on the bike.
Anyway, just wanted to let you know how it's going and thanks for all the advice you've all given me so far!
