    Can I cut my fork?

    I have a bike with a bent fork, and I just found a replacement fork, only the steerer tube is a little longer than mine because the frameset I'm getting the fork from is a larger frame. So....

    Can I cut and rethread the steerer tube down to the size I need, or is there some reason that can't be done?

    The short answer is that it can be done. A more accurate answer is that cutting fork threads with a die is real hard physical work and easier than you'd think to screw up. I think that it's one of those projects where the confidence of the bike mechanic is inversely porportional to the likelihood that they've ever done it before. If you need to add more than two or three threads it might be cheaper to just find the right size fork.

    My options are to have a frame guy straighten my bent fork, or to find another fork. I'm not sure if the fork can be straightened, or how safe it will be if it is straightened. And this fork is the right fork, except that it's too long. If I get this fork, I'd actually have the frame guy cut it for me.

    One more question. The bike has triple-butted tubing. I read last night that bikes with butted tubing only have the butted tubing in the three main tubes and the steerer tube. If the steerer tube is butted, will that be an additional problem Re: cutting and threading?
