does anyone else have rx-1 pedals?? i just got in mks toe clips and it seems that the holes to attach the clips to the pedals are threaded and there isnt enough clearance on the other side to screw on a lock nut. i screwed the bolt in as tight as i could but it seems odd not to have something on the other end. maybe keirin racing saving weight? has anyone had problems with their clips coming loose with this set up and if so, how did you get around it?
