Howto: Road bike with 135mm rear on Campy?
I am looking into having a bike made with S&S couplings. I am also
looking into having this made to accommodate disc brakes and so will have a 135mm rear end. What are the options for running Campy 10- speed on this? The reason for disc is that inevitably when riding in Europe you will hit a patch of road that has been recently chip-sealed. The tar sticks to your tires and then the small aggregate they place on the roads sticks to the tar and then it gets all gummed up around the caliper brakes, grinding up the rims and forcing you to stop to scrape off the sticky goo. Though rim temperature isn't really much of a problem on a single bike, the disc brakes do make it easier to use on lengthy descents and have better wet-weather performance at the expense of the occasional howl of the disc. "Back in the day," Campy 9 speed with a 9 speed Campy derailleur would shift just fine on a Shimano 9 speed cassette, but I notice that nobody is recommending that for the 10 speed stuff. So, what hub/ cassette/chain/derailleur does one run if they want 135mm spacing with 10 speed Campy components? |

Peter Chisholm (Qui Si Parla Campagnolo) has recommended mixing not only S10, but S9 with C10 setups. Based on that advice, I have on my CX bike Veloce 10 speed shifters, a Centaur long cage RD, Deore rear hub, a SRAM PG970 11-34 Cassette, KMC 10speed chain and a Veloce UT compact crank. Works great on all combos except small/small, where the chain is at such an angle that the big ring's pickup pins keep trying to grab the chain even though the FD isn't touching it. My road bike doesn't do that with the same crank, so I figure it's the extra 2.5mm that the small cog is out from center. What I've wondered, though, is if Campy hubs can be respaced to 135mm? I've contemplated adding a spacer between the oversized axle and the end that goes into the dropout, but wonder if the axle end can still screw in far enough. Anybody tried it? |

American Classic, Wheels Manufacturing, maybe IRD, maybe one or two
other companies make 9 and/or 10 speed cassettes that fit on the Shimano hub sline pattern, but the cogs are spaced exactly like Campagnolo. So you could easily run a Shimano Deore XT, XTR, etc. hub with 135mm old spacing and use the conversion cassette and shift it fine with Campagnolo Ergo.

I take it you will be using a Shimano type rear hub? http://jtekengineering.com/shiftmate.htm I use one to shift Shimano 9 speed stuff with 10 speed Campy Ergo, works great. I hear the other mix and match combos do too. I'd rather go this route and have the freedom to swap "off the shelf" cassettes than go the expensive spaced cassette route. Marcus |

Campagnolo 10s ERGO and RD shifts shimano/Sram 9s better than Campag 9s and shimano 9s. The cog ctr to ctr differences are less with Campag 10s and shimano 9s than all 9s stuff. Get a shimano disc hub, any shimano 9s cogset and chain, rec the longest cage Campag RD if you want big cogs/low gears. |

I have not but I wonder if you could put a thin spacer under the right side axle end and then another really thin one in the left axle end and get pretty close to 135mm(133??) |

Didn't Zinn say that SRAM's 10 speed cassettes work fine in an otherwise Campy system? Lennard had Campag 10s ERGO, a set if Sram derailleurs, f&r, and it shifted shimano/sram 10s spacing. |
