I have crank brothers clipless pedals on my giant xtc 1 right now and i am ordering welgo mg-52's. One dilema, i am having trouble removing my crankbrothers pedals. I dont have a 15 mm pedal wrench but the stem of my pedal is not square so i couldent use the wrech. but i can fit in an allen key but it is impossible to turn, ( i understand that you are supposed to turn the wrench clockwise because of the threads.) Please help. I need a very descriptive step by step answer.
