I run exactly the set up you're talking about on a 135spaced frame - it's also worth thinking about the fact that on a 68mm shell BB you'll need to achieve a 53mm chainline for the bolt on. as an example that's a sugino 75 with a 125 (exist?) taper bb. That'll look shit and be shit. There's a reason 135 frames tend to have 73mm bb shells.
Me: I have a good 'ol American old school tank : 1971 Schwinn Sport Tourer that I bought new and am still riding it (68mm bottom bracket)
Qt: MrWheeler .. did you spread from 120 to 135mm??? Anybody here do that? I'm currently cold setting the rear, and have it spread from 120mm to 128mm using pipe clamps to do the spread ... nice and even. Had to spread the rear to 155mm for 1/2 day... I used pipe clamps at the brake block/fender holder cross tube and near the seat tube so stress wouldin't be applied to the weld joints Originally wanted just to go to 130mm ... now I'm thinking of going to 135mm. Now I read what Roryeaglestone wrote about the bottom bracket 68mm versus 73mm. Are there problems with the chain line?
Heading toward 135mm figuring the extra pipe clamps will relieve any bending stresses caused ... I guess I may have to spread the rear up to 160mm/170mm to get it to spring back to 135mm . ... Anyone with experience here??? Thanks!
