First, I want to comment on how great this site is. It's been a great resource so far.
I've started cycling for these reasons:
1) I'm training to climb Mt. Rainier and running isn't good on my clydesdale frame (6'2" 245lbs)
2) My pickup truck is aging fast and I don't want to replace it with another car
3) I was an auto mechanic for the better part of 10 years and I harbor a passionate hatred of cars
4) I like how simple bicycles are compared to other modes of transportation
My ride of choice is a 2006 Specialized Allez triple. The LBS gave me a deal on it and i'm sure it'll make for a nice commuter.
I'm also interested in bike mechanics. My project bike is a Specialized Allez M2 Comp. I'm unsure on what to turn it into.
Thanks again for the great site!
