  • So I bought a 1/2" sliding t-bar and some hex bits, and it's still not budging at all. The bolt isn't rounded off, but it's obviously resisted quite a bit of pressure so far and the hex bit is slipping before the pedal moves.

    Should I try again with some of the Chill Zone stuff? Or is there anything else I could try?

  • I had a very similar issue a while back. I managed to snap 3 hex keys and a hex bit!
    Took it to my LBS and the mechanic slipped a silicon glove over the hex bit to help stop it slipping. Still took 2 of them and a very long breaker bar to get it loose.

  • Slipping as in it's climbing out of the recess in the pedal?

    You could try some plumbers freeze spray on the pedal axle, sometimes that's enough to reduce the force required to overcome the friction between the two parts (by shrinking the axle relative to the crank).

    Otherwise what I'd do is to clamp the hex bit into the pedal recess using a vice so there is absolutely no way it can come out, then use something (ring end spanner round the hex bit with extension bar over spanner) to turn the hex bit.

  • Have you tried turning it in the opposite direction to the one you are doing? It might help budge it or break the deadlock.
