dude! I'm a beginner - I always have been, always. don't lose that beginner mind, the fun kinda goes out of it when you do...

Just take the clips and straps off until you are really really comfortable riding your bike. Then you can make a choice between clips/straps, step-in pedals, or maybe you'll always like going commando (uh, no straps, no nuttin').

Spring for some shorts, though. jeans really suck for more than about 2 blocks. And...if you don't already have one...lay out for a helmet. I've broken nine, with my permanent beginner attitude. That is about 6 maiming injuries and three dead guys, all me, if I hadn't been wearing a helmet.

btw, once you get some experience, you'll probably find that a 58 might be a little small, even.
