    Loose crank

    I have a new Truvativ GXP outboard bearing SS crank. It is continuously loosening up on me. I have to check it once or twice per ride to make sure it hasn't loosended up again. Tonight I will pull it apart, clean the bolt and threads really good and apply some teflon tape before I really torque it down.
    Does anyone have any other recommendations? Does this happen with other cranks?

    Ahhh! No teflon! It'll make a mess and won't solve your problem. Clean as you were planning. Use some citrus degreaser. Try again. If it still happens, try a bit of blue loctite on the threads.

    btw, your handle belongs to somebody else who's been in the mtb game for a hell of a long time, even if he didn't add an extra "S" to the front end.

    Tape is good for some things, but for other things, grip is required.
    I gotta roll, can't stand still, got a flame in my heart, can't get my fill.

    longer crank bolts

    i had the same problem with a phil wood bottom bracket (square taper spindles) and raceface cranks. ended in a catastrophic failure of my bottom bracket...the spindle sheered completely off during a hard climb...leaving my pedal, crank, and chainring dangling from my right shoe, still clipped in. word from phil wood: need to make sure your crank bolts are long enought to have a substantial number of threads for securing the cranks to the spindles.

    Didn't know

    I'm somewhat new to the SS thing and had not heard of the other soulrider. I added the extra S to denote my newfound SS passion. No harm intended.
