    Crank arms stripped... what now?

    I put my pedals on when I got the bike. They went on totally easy. Before anyone asks, it was the drive side, which is righty-tighty/lefty-loosey. I put them on correctly.

    I finally went clipless on my mountain bike and LOVED the SPD platform so I went to put a set on my road bike. As I was taking them off, it was clear something was wrong. I had to muscle them off and when I finally got them off the threads were stripped.

    What caused this? How do I fix it? Tap/die, helicoil, new crank?

    Did you grease the threads when you installed them?
    Now for the fix. A tap wont work if the material is gone. There is an insert available. Its an insert though, not a helicoil. Its much better. That being said, i would replace the crank.

    Agreed that it is rarely worth doing. The kit is now $134. And unless OP is familiar with using a tap, then paying someone else to do it adds to the cost.

    And in case you were wondering, it's an unusual thread, not found much in the outside world. Helicoil don't make an insert in this threading.
    There's sometimes a buggy.
    How many drivers does a buggy have?

    One.

    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.
