I have just recently started biking for exercise and commuting to work 15 miles RT. I am considering getting clip less pedals, I am looking at the Shimano Pd-m520 or the 540.
Is there any significant difference between the two, should I just get the 540 right out of the gate? Any advice to keep from falling, or is it a right of passage? I'm 6'6" and on top of a bike it's a long way down LOL.
