I don't know if I should be worried about going to a clipless, but you gotta start somewhere. I heard that as a beginner I should just prop up my bike in a hallway and practice for a good while until I get a hang of it before I go out. Also that unclipping earlier than I think will help and to lower the tension setting. Any other pointers for me? Also as far as shoes go, do I just get any pair of road shoes and then get cleats after to fit my clipless pedals? Are the cleats "pedal specific"??
