I am a bike mechanic at LBS, Biketek in Springfield IL to be exact. I just purchased a Raleigh Rush hour for winter workouts, mainly trackstand sprints and speed drills. I am only 5'9" on a tall day, so I got the 50cm, which actually fits quite nicely showing around 7 inches of post. I generally ride 175mm cranks being that i have 32.5inseam, so I was wondering if anyone had some advice for me. I would like to have 170 or 172.5's. Any advice is helpful.

P.S. I really like this style of riding. Almost broke my wrist on the first ride. But I am going to keep riding it!!!!
