I have about 450 miles on my first bike in years. The shop put toe clip pedals on it for me the day I picked it up. They have been fine, but I am going on my first organized ride Saturday and I bought a pair of shoes and was thinking about putting the Crank Brothers Smarty clipless pedals on for Saturday. They came with the bike. Is it just a matter of spinning one pedal off and the other back on? Or do I need a special wrench? Also, Am I just being stupid to make the switch before the ride? I am looking forward to using the new gear, but maybe I am supposed to test things out closer to home first?
