1. I'm spending way too much time on BF(for someone who does not have a bike)- but I'm learning alot about bikes. My 2nd hand Giant roadbike was stolen after having, and riding it for 4 weeks
2. I can only afford a second hand 8spd Sora bike but want to own a 10 speed, new 105 bike
3. I don't have the patience to wait till Oct 2010 when I will have the money to buy my new 9speed bike, cash
4. I have no brand loyalty, except for Shimano
