My damn crank bolts keep coming out. im only a beginner and i dont want this problem to keep annoying me when i go on to bigger jumps.
I've tried stuff called lock 'n' seal, but i dosent make much difference. :?:

    try doing them up like you would with nuts on a car wheel.

    do opposites, then tighten them bit by bit, rather than going for it with each individual one.

    oh yeah, they're just regular steel ISIS allen key ones.

    if they have been coming loose often then the crank splines could be dead... new cranks.

    yes and? a worn spline will allow the crank arm to move which will work the bolts lose.

    Same thing happened to my old hussefelts, they kept coming lose and i had to ride with a 8mm allen key, eventually the wobble wore away the splines on my crank arms and i had to replace them. you'll probably find that top end cranks dont ever come lose. my northshores havent in over a year :)
