I recently bought a used Centurion road bike on eBay, from the late 80's with Shimano 105 6-speed drivetrain. The rear hub is a traditional sort, with a freewheel. Problem is, the axle is rather bent. However, the bearings seem perfect, which means that the axle is bent only on the exposed portion. I might be able to straighten it, but I'm 6'5" and 185# and would probably bend it again anyway. Should I try to straighten it out and use it, or is this a futile endeavor?
My alternate option is to use a mid-90's 105 freehub (which will accept 8/9/10 speed, 130mm spacing) and build a new wheel, perhaps with the rim from the current hub. (The rim is a Wolber anodized, box-section rim, seems to be in very good shape.)
Apart from concerns about 6-speed vs. 8-speed, is it worth bending the axle back to straight on this freewheel rear hub, or will it likely just bend back in short order? Thanks.
