Campy/DA Compatibility?
I finally pulled the trigger on an 8spd DA group for my Columbus TSX frame. DA STI 7700 brifters & 7400 RD. I have some nice Open Pro rims, but they're 36H and am having a hard time finding 8spd hubs. I saw these Mavic rims with Campy hubs and cassette on EB and think I remember reading that there may be some compatibility between some Dura Ace and Campy components. Is the Campy cassette spacing compatible with STI 7700 and chain? Here's a link to the Campy wheelset, it does not say what model they are.

I don't think they made many 36' hubs. I have an older Veloce hub and even it is 32'. as for comnpatibility. on one of my bikes I have 8spd da DT shft and RD with a Campi 8spd cass. it works fine. I had started with a sachs 8spd freewheel on my C-Rec HF hubs but after a few axles I switched to the cassette.
if I could find 8spd Campi DTs that could afford (or wanted to try and out bid the snipers) I would certainly use them instead.
btw nice wheels

In my experience, 8sp spacing is 8sp spacing. I've run Shimano-spaced 8sp cassettes with my Campy Record Ergo with no problems, I don't see why the reverse wouldn't work as well.

Your 8spd DA DT shifters and RD working with a Campy cassette would make since if they are non-indexed. However, I'm not sure if the spacing between the Campy cogs and teeth will work with DA STI brifters and chain?

Except for the early 10-speed Dura Ace hubs, I believe you can use any shimano-compatible 8/9/10 speed rear hub and just put an 8-speed cassette on it. The freehubs are the same dimensions, the difference is in the spacing of the rear cogs on the cassettes. I'm running 8 speed on a DA-7700 rear hub currently.

Campy 8s spacing = 5.0mm c-c. Shimano 8s spacing = 4.8mm c-c. Some have made this work w/o issues, others have not.
An since you're already mixing periods w/7400 & 7700, I'd just buy some newer Shimano hubs, 8s, 9s whatever, just avoid ones labeled 10s only.

Your shifters are 7400 STI (8-sp) DA. The FD is 7410, the RD 7400, and the crankset is 7700, with the bb. I've run the same group with an 8-sp Chorus cassette on Vento wheels, no problem.
They shipped today, Priority Mail, Flat Rate box, with new hoods, FD, RD, crankset, shifters, hoods, bb, cassette (HG). If you don't need the cassette, sell it or hold it in case you get wheels for it.
I think you'll like them, and as for the price, thank cudak888 and Spinz. They made it possible, I just passed it on....

It would be nice to have new hubs; however, I've been looking on EB for a couple of months for 36H Shimano hubs and the only ones I remember seeing are new 8,9,10 spd DA for 200. I think the Campys with Reflex rims might go for less then that.
Next question is, if its the cog spacing that is the issue, will a shimano 8spd cassette fit a Campy 8 free hub?

I've been corrected by the seller, they are 7400 brifters, Its the crank that is 7700. I wonder why it works for some and not others?

Possibly. This does seem to be getting more complicated then it should be. I bought the Mavic Open Pro rims many months ago just for this bike. Little did I know at the time, that 36 hole hubs were going to be so hard to find. I guess I'll just have to be patient & maybe some will pop up. It doesn't sound like it would be worth taking a chance on the Campys working.
