I've come into a set of Zipp wheels, and the rear has a beautiful Campy Record hub (no cassette on it). The road bike I’m building has a 10-speed Shimano drivetrain with Dura Ace bar end shifters (indexed), and I’m wondering if there’s anything I can do to make the rear wheel (with the Campy freehub) workable with the 10-speed Shimano road drivetrain?

Shiftmate

Just set the right shifter to friction.

I haven’t done it with 10 speed, but I’ve run Campag shifters and derailleurs with Shimano 8 and 11 speed cassettes with no problem. I set my indexing based on the middle cogs (so 4/5 for 8spd, 6 for 11, and presumably 5/6 for 10), and then set the limiting screws at either end. The difference in cassette width between Shimano and Campag 10 is 1.6mm, so if you “split the difference” this way, the chainline is within 0.8mm of the cogs.

No guarantee it’ll work to your level of satisfaction, but I’d give it a go before spending on a shiftmate or replacement free hub body etc.

11-speed Shimano and Campy cassettes have the same spacing, so they will work together no problem; and as you've done with the 8 speed, there's enough margin of error that it will work.

But I do not think this is the case with 10 speed, and you won't get nice shifting. The cassette spacing is not the same, and the margin of error is too small. You can probably make it rideable in some gears, but certainly not all. If you have a high tolerance for imperfection, maybe that's not such a big deal .

OP UPDATE! I found another workaround altogether, but I’m still interested in all these suggestions (you’ll see why).

I was perusing Craigslist last night and happened to come upon a great deal on a beautiful late ‘80s Miele Latina frameset (Columbus SL tubing, Campy headset) and realized I’ve got a bunch of Campy I was needing a place for (was going to part it out), and realized I could run it all on this beautiful frameset. So I’m thinking to get an 8-speed Campy cassette for the Zipps and run it with the rest of the Campy.

HOWEVER I’d still be interested in riding these Zipps on the bike with the 10-speed Shimano drivetrain, so either running the right Dura Ace bar end shifter it in friction mode or getting the Shiftmate would be the options.

So now I’m wondering: would I need the Shiftmate 1 or the Shiftmate 4? (Or some other one?)

First you need a Campagnolo cassette in there. Shimano and SRAM cassettes will not fit on a Campagnolo hub.

More basically, what is the dropout spacing on your Meile frame? For the 8 speed or higher hearings you need 130 mm spacing. So measure the space between the dropouts and you should get 130 mm or 5.12” or (less accurately) 5 ⅛ “. If it is not this value you need to see if there is a trusted local bike shop which has the skills to cold-set your rear triangle to 130 mm.

RGMN

Depending on the age of the Campag hub you may be able to change the freehub to a Shimano compatible freehub. Then you can use a Shimano 10-sp cassette on the Record hub. You would need a Campagnolo P/N FH-BO015X1, but it will only work if you have a non-cutout axle. The non-cutout axle is P/N FH-BO001, but if you have to replace both it probably is going to be more expensive than getting a good Shimano compatible hub.

Why is this posted here and not the proper place?

Because I have no idea where things are supposed to be posted! Happy to have it moved to wherever that would be

It's a question about something mechanical. It should be obvious. Take a look around for a minute, there are tons of forum sections for a reason.

Road Fan

I've never heard of this! For what kind and age of Campag hub, and what kind of Shimano freehub, will this work? Sorry, I don't know what those part numbers refer to.

Leinster

Granted, it might not work nearly as well with 10 speed, but I will always default to exploring the cheapest option (ie, just get a Campag cassette) and see if it works acceptably, before spending extra on other parts (the shiftmate).

praise dakinis

Ok, I’ll give it a try next time. Sorry for the hassle!

RGMN

Sorry, got the cutout axle info wrong. This only works on hubs WITH the cutout axle. If you have a non-cutout axle you need a new axle P/N FH-BO001.

From what I recall this works on pretty much any of the OS hubs with cutout axles (2006+.) As for the part numbers:
FH-BUU015 - Freehub for Campy 9 to 11
FH-BUU015X1 - Freehub for HG 9 to 11
FH-BO001 - Cutout axle for pre-2006 OS hubs

I've fit many 130 hubs in 126 steel frames and rode them for years with no issues. It's only 2mm difference on each side. I have an '80's Trek that's actually been cold set to 130 but that isn't even needed.

A 10 second Google reveals:

Mixing and matching 10sp Shimano/Campagnolo seems to be a bit questionable. You might be able to get a Shimano freehub body for the Record hub, I have no idea. Regardless, that's a 20 year old niche part, good luck finding if it exists.

In unrelated news, I currently have a Quarq (SRAM) crankset, Super Record levers and derailleurs, and an Ultegra cassette and chain running 11sp on one of my bikes. Works perfectly.

RGMN

The Campag P/Ns I gave are all current and QBP actually have them in stock. They are current parts for the wheels both Campag & Fulcrum are selling.

Road Fan

Just call it my opinion, then.

Road Fan

It may be questionable now, but perhaps 20 years ago it was regarded as not possible. This is why I would like more details of how this works now. Most of my bikes are Campy-based, but for one I'm planning to build next Fall I would like to use my very nice set of Shimano 6500 hubs. I might go with clinchers (it has Mavic Open Pro) or I could put on Nisi of Mavic tubulars and to with 36 mm Strada Bianca tubulars. I also have several pairs of extra Canpy 10sp Ergopowers, After I pick a 10sp Shimano derailleur I would put it all together with a Shiftmate and ride the bike that way. Or I may use it on my Terraferma, which I would also like to convert to indexing. I got teh new Shiftmate for something like $40, which may be less than the costs of freehub conversion.

I would also do coldsetting to match the frame dropout spacing to the intended wheel OLD. It might just be opinion, but based on my engineering training I beleive the stresses inside the hub based on the forces between it and the frame are smaller when there is not a twist applied to the hub by the dropout.

Many riders have stuffed wheels into frames and had that cause no problems. That doesn't mean I'm wrong, I would just rather not do that on one of my bikes.
