  1. I was curious how far might be the max to "cold set" a steel frame?

    I've got a 135mm frame that I would like to have 120, and while I've
    gone 126 to 120 or 126 to 130 with no problems, 15mm seems a long way to
    bend, even with the tools to make the dropouts parallel.

    thanks for suggestions

  2. Well you're pushing in as opposed to out, so little chance of popping
    your brake bridge.

    It *is* quite far--any reason you can't throw a new axle on your SS hub
    with some spacers to make it 135?

    Agree with the axle as the better solution, but aren't most SS rears 110mm or was there external info that told you SS rather than fixie or IG hub or 5 cog rear?

    No reason I absolutely couldn't respace the wheel, but I've got 3 other
    fixies that have 120mm spacing and want to be able to swap wheels
    between them as necessary.

    No real issue making it smaller. Bigger can pop off brake bridges or
    crimp tubes. No big deal going to 120 from 135 BUT ya can also get
    axles for just about any hub to get out to 135mm...even solid ones.

    Track rears are 120mm.

    First of all, to achieve cosmic balance, you must mail me one of your
    fixies. Four is just unfair when I've only got one...

    😄

    Just go for it. I like tying string to the rear dropouts and wrapping
    around the head tube when doing this--you can measure the rough
    evenness of your progress by checking the string's relation to the seat
    tube. Very scientific--but it works well enough. A big ass crescent
    wrench can wrangle those dropouts back into a parallel configuration.

    have fun!

    And then you will need to send one of them to me... since I have none.

    You're thinking of the Redline Monocog, which used to have 110mm spacing.

    Most MTB SS hubs are 135mm.
