Hi all, I recently acquired a 1993 bridgestone xo-1 in bad shape & will be attempting to restore it. I'm sending it to velocoluor for a repaint & have asked them to spread the rear triangle to 135mm. the original spread is 128mm, I guess to accommodate 126 & 130 rear wheels. I'm now wondering if this is a good idea, my original thought was to put mtb wheels on it. will this affect the chainline? I'm also looking for advice on a new bottom bracket/crankset combination any ideas? thanks

I own an XO-3. Rather than spread the rear triangle, I had a wheel set built with some 105 hubs and Sun CR18 rims. Had to convince the builder thats what I really wanted.

For a crank, I'd go with a Sugino XD600

You prob don't need MTB hubs. Shimano road hubs are really tough.

You can use a lot of different cranksets. Just pick one that looks good
to you. That Sugino would work fine, I used one for a while.

I test rode an XO1 back in the day. It's a sweet bike, you'll like it.
It was even on sale, still kicking myself over that one.

I agree with the Sugino XD crankset, great choice for that bike. As for the cold setting and the chainline, if you want to run a modern mtb hub, then go for it. You'll need to play around with it to determine the bottom bracket length that gives the best chainline.

My only concern about cold setting that bike would be that it is a collectable model. But if you're building it simply to be the best bike it can be for its purpose, go for the 135mm dropout spacing-

Quality suggests 113mm BB with 130mm dropouts and 118mm with 135mm dropouts.

Yep. However, as evidenced by my recent LHT build with 135mm dropout spacing, you just can't tell until you try it. The stock LHT comes with a 110mm spindle with the Sugino cranks, as listed on the Surly site. I read the recommendations regarding 113mm and 118mm, wondering what the heck was up with the 110mm on the LHT and the Sugino triple. Sure enough, 110mm was the one that gives the most neutral chainline. That's what I went with on my LHT build-

Thanks for all your responses. According to the bridgestone specs the xo came with a 117mm spindle, I think its on the short side because the inner ring just clears the chainstay. Like you said Well Biked I'll just have to figure it out once I get the wheels & crankset figured out. My reasoning behind spreading the dropouts is mostly financial- I have a set of wheels with xt hubs & cr-18 rims laying around. like most of the other parts on the bike, the wheelset is not worth trying to save, it looks like the bike was ridden hard for 10 years, then stored in a damp basement for the next 5. If price were no object, it would be rolling on new custom built wheels with road spacing. the sugino crankset looks great, a perfect replacement for the original sugino gp.

You could respace the XT rear hub to 130 mm by removing a 5 mm spacer, shortening the axle and redishing. Your current dropout spacing would work and your existing wheels can be used.

WOW! great idea! I've been going back & forth with this because I really don't like the idea of prying that frame apart.I just took a look at my wheel & it looks doable I'll just need a shorter dustcap (like the one on the front)Thanks!
