OK I am truely a newbie I just started riding about a week ago. I have no idea what those are. I am assuming I have egg-beaters because when my foot comes off the pedal they just spin around. I would like to get something to help me pedal in a circle but I'm afraid to lock in until I've been riding for a little longer. Any thoughts? BTW I love this forum because all the post's are very encouraging and that really helps.
