Haha, I'm pretty happy with my 46-15 gearing for the most part though. Only time it was really hard was climbing in SF, but we could push through regardless. I'll eventually swap it out, but I'm not sure when I'd need to.
Also, I was just talking about that today. I mean, the stock cranks don't seem to be anything amazing, so I've been trying to find a nice crankset to replace it. And I'd just get a new BB to match it. Weird thing though is that the BB is 103. And if I measured right, I think I'd need a 97 BB to make it fit. Kind of an odd length, I think.
