OK, so, I'm building this bike. Among the parts are a Trek 7300 frame (a 700c hybrid) and a Shimano rear hub. I've built the hub into a wheel (second one I've done!) and *then* discovered that the hub I'd measured for this frame was, in fact, a different hub. That one had an OLD of 135mm. This one —*the one I spent an evening turning into a wheel, the one with the right number of holes for the rim — is 130.
This bike's destiny is to have 8 gears, no more or less. So I don't need all that room back there.
So, my question is this: it seems to me like I could carefully bend the stays 5mm closer to each other. That's 2.5mm each. Not a big deal, I figure. But this frame is aluminum. I don't *expect* trouble, but I figured I'd ask before grumbling around and rebuilding this wheel, of which I am already quite proud.
My plan is to tie a rope around the dropouts, stick a piece of wood between them, and twist until, when I release, the distance is 130mm. Does anyone anticipate an issue with this?
It's got the "fork" type of seat stays. Here, I'll show you.
Edit: A secondary question is, how much of a hassle is it to change out the axle on a really normal Shimano hub? Maybe that's an easier thing to do.
