Hi, to anyone who has assembled - reassembled a look pedal (preferably the keo). I have just removed the axle on my keo carbons for a regrease. Can you tell me how tight the plastic nut an the axle - pedal body connection should be when you reassemble. It seems if I tighten up too far it starts to tighten the bearings. Is this ok. Should it be just snugged up enough to allow free rotation with the bearings ?
