    Coldsetting Titanium?

    Is it possible to reset the rear dropout spacing of my old ti frame from 130 to 120?

    I've seen pics of it being done, over on roadbikereview forums, I think. Had much to do with thick-trunked trees and a come-a-long and several heave-hoes. Not sure what he did about getting the drops parallel again, or rear alignment (think he lucked on this part and spread symmetrically.

    Think I'd rather make a fixie of it.

    I assume you want to make a fixie or track bike out of a road frame. Why not just put a 130 mm hub in it and locate the cog with appropriate spacers.

    Yes, that would be the most practical thing to do. But I just happen to have an extra set of track wheelset. I guess it might be easier to install a longer axle and space it out to 130. That'll work too.

    We had to tweek one hit by a car. I believe it would have been simpler to hit it with another car.

    The nature of titanium makes it very, very difficult to cold-work. I've heard stories of titanium business cards that can be bent so that the ends touch each other (so, in half, but more in a circle) and it springs back to its original shape. As I understand it, the difficulty of cold-working is one of the reasons that Titanium bikes cost so much - the raw metal itself ain't extremely expensive.

    I'd say just get a longer axle and more axle spacers for your hub.

    Alternately, Chuck could find you some cars to do the job for you

    That might work out better for you. I don't think Ti is as forgiving as steel. It should be easier and cheaper to use a new axle and spacers than rebuild the entire rear wheel. Good luck and post some pics of the finished project.

    One more reason for making the hub fit the frame rather than making the frame fit the hub; if you change your mind and decide the fixed gear isn't for you, you can go back to a cassette hub with no effort.

    As noted, cold-setting Ti isn't for the faint of heart.
