Hi all, I’m using a Profile hub and 145mm crankset, and basically what’s wrong is that the left crank seems to slide on and off really easily, literally I can slide it about with my fingers. I never thought it should be this easy, and it seems when I tighten the crankbolt for it, the left crank seems to develop a little bit of play after a while of hopping around.
I put copper grease on both the hub spindle; and, the threads of the crankbolt. Should I put blue loctite on the crankbolt thread or something?
Here’s my theory: I think that since the left crank slides on and off soo easily on the hub spindle, it hasn’t got anything to hold it still except for the crankbolt, so all the vibration from hopping may have shaken the crankbolt a little looser, making the crank develop a little bit of play/wobblyness. I am pretty sure that a profile crank is meant to be pretty tight fitting onto the spindle 'cos that’s meant to help keep it in place isn’t it?
Would appreciate any help from you guys
