    I am in the process of experimenting with a crank forward bike design with
    both wheels being 26 inch . My steering is very sensitive and I was thinking
    that an increase in positive trail would be worth investigating. My setup
    has 1.5 inches presently. I would like to increase it to 3 inches plus. The
    forks are Rocky Mountain and very strong. In the past I have cold bent road
    bike forks with an electrical conduit bender successfully. Has any one tried
    cold bending these mountain bike type of forks and been successful? Has any
    one tried heating and bending these forks with success? What method did you
    use?

    Cheers...Gerry

    You'd probably have better luck in rb.tech.

    Yes, there is some useful info there, but Sheldon only has an article
    about respacing the frame, not the fork like this fellow is talking
    about.

    OnTopic: In fact I respaced a bike frame last night, from 143mm back to
    it's proper 132.5 mm spacing. *High-tech* measures involving a
    chair, one 2x4x10, a ruler, and some cardboard were involved.
