View Full Version : older carbolite fork

I have an older Peugeot mixte frame, "Marseille", that I've converted to singlespeed. However, I just realized that the spacing between the fork arms seems to exceed the axle length of the 27" wheel that came with it. The wheel goes on, but one of the fork arms has bent up the QR spring, and the I can't really tighten the QR down enough. We're talking maybe 2/3 mm too wide. There's also no room to add spacers/washers on the axle.

So does this mean that the fork arm's just a little bent? I would think this immediately, except that the QR really doesn't tighten it down enough. Is there some kind of easy method of minor cold-setting I could do to the arm? Or, alternatively, should I just go find a new axle to replace this one with?

Thanks, as always.

Cold-space the fork and re-align the dropouts.

Kurt,

Before I do this, I just looked and realized the wheel has a couple of those "safety" thingamajigs that are levered from the axle onto the front of the fork dropouts. Maybe 1 mm wide on each side. I think I'm going to try taking those off and see if that'll provide the axle enough space for the fork dropouts.

Thanks for the advice.

Sounds like you're using an '80s Schwinn rim. Worth a shot to remove them, for I'm pretty sure the axle is washered as well.
