Respacing hubs(10 posts)

Okay, here's dumb question of the day. I need a 135 spaced rear wheel for my all-rounder. I was going to scavenge the wheelset out off my unloved MTB (Ringle 8/9 speed Shimano hubs). Now I'm thinking of using drop bars and Campy ergo on the bike. Is it possible to re-space a 130mm Campy rear road hub to 135 and build up a set of durable enough wheels 26" wheels? It's a steel frame, so could I pop in a 130mm rear wheel and squish the dropouts in without getting too far out of alignment? Sure, I can use a Campy 9 speed shifters and rear derailleur and a 9 speed Shimano cassette and fake it, but is it too much to ask to have an all-campy bike??
Oh, and one other question: Is there a rule of thumb on crank sizes? I use a 172.5 double, but the Campy triples are 170 or 175. Any thoughts?

so u r going to lace up a campy hub to a 26" rim? Thats alot of work to just have all campy. if you don't have the wheel already built, then use a mtn bike hub. I wouldn't squish in the dropouts. Thats pretty ghetto.

you can prolly just put a 135mm mtn bike axle into the campy hub. I know you can do it with shimano hubs not sure about campy but don't see why not. Now that would be cool.

You'll need a longer axle and a 5mm spacer for the left side. Be sure to do the hub work before you lace the wheel or you'll have to redish the wheel afterward.
So it will work. Ever tried it?? -nmKurt H

I havn't done it with Campy, but it doesn't look very hard.Spoke Wrench

Getting the correct axle looks to me like the hardest part. Axles come in several different lengths, I suspect you will want a 146mm. They also come in two different thread pitches. You will want 26tpi to match your Campy cones.

Good luck.
Where to get the axle?Kerry

This is the key issue. Campy axles are specific, you you can't just swap in "any old MTB axle". I'd be surprised if Campy actually made the axle to space their hub out to 135.

I was going to do that too, but then I started looking for an axle for a Record OR hub. They do not seem to be available any more. There may be one on a shelf somewhere but I can't find it. The Campy rear axle has one of the races built on the axle and It just doesnt have enough meat to add 5 mm of spacers. I don't see a practical way of modifying a standard style axle to work.
better idea...C-40

Use the shimano hub with 135mm spacing and get one of the campy spaced "accelerator" cassettes from excel sports. Then there will be no hub or cog spacing problem.

Campy 10 shifters can also be used with a shimano 9 derailleur using a mickey-mouse technique that routes the shift cable under the bottom of the cable clamp to effectively length the lever arm (and shorten the throw) on the shimano derailleur. Info is available at Look under hubbub technical.
I thought of the cobbled version..Kurt H

I looked at the accelerator cassettes, but I'd like to be able to swap cassettes around some and the accelerator cassettes were expensive last time I checked. This is an all-rounder after all!
I was more seriously considering the "mickey-mouse" version or the Shimagnolo adapter which bolts onto the derailleur and alters the angle of the cable to create a seamless Campy lever-Shimano derailleur experience. But is it too much to ask to have an all campy bike? C'mon, can't a guy aspire to have something truly something special???
