Campag4life

Some have read the Zinn article about mating Campy 10s ergolevers with Sram driveline but I would prefer the reverse.

I have been considering Sram shifters with Campy driveline. I like the Campy UT crankset...Chorus Skeleton brakes and front and rear derailleurs and don't really want to change my wheelset/hub to a Shimano or Sram rear cassette but believe I will prefer the Sram double tap shifter ergos and hood comfort over pre-2009 Campy and even the freshly redesigned Campy ergolevers which are a bit closer.
So...have been doing a fair amount of reading about the compatibilty and some know that Campy does not have uniform detents with their R.H. shifter rachet wheel because of their non-uniform cog/cassette spacing...but it can be made to work with a Shiftmate so will likely have a go at some point.

If you guys haven't seen this cool component mix calculator...it is pretty clever and worth a look if you are considering mixing components:

I was playing with the mix calculator, and I'm not sure it's reliable. For example, it says that DA 7900 brifters are manufacuter approved to work with non 7900 Rear derailleur. IIRC that's not accurate because of a change in the amount of cable pull from 7800 to 7900 brifters.

So much for the "Campag4life" handel, maybe you should change it to "SRAM4life"??

I have a JTEK shiftmate. 10 speed SRAM Rival going to 9 speed Shimano. Shifts better than my full SRAM Force setup (because I'm lazy and haven't adjusted the barrel... )

And the end of the day people believe what they want to. I can write volumes about this stuff. DA 7800 to DA 7900 is easily compatible with a simple shiftmate in the rear to compensate for cable pull differential if say retaining a 7800 RD with new 7900 shifters. It will be dead nuts because unlike Campy, Shimano and Sram have linear cog spacing in their cassettes. Zinn pointed out Campy Ergolevers will work on an all Sram driveline very well even without a Shiftmate.
There is a pretty substantial cable pull difference between the two...Campy's being aggravated by first five small cog gear spacing is linear and close...then 6&7...then 8&9 which are deliberately spaced wider to prevent chain rub when X-chaining large cogs. Bottom line is tolerances within most systems will account for cable pull deltas between mfrs even though they deliberately design them to eliminate cross functionality between mfrs. Many also don't know that a Shimano cassette on an all Campy driveline shifts perfectly even though the cassettes are quite different. There are many permutations that will work and with a Shiftmate to shore up cable pull differences which is only one third of the discrepancy...derailleur throw ratio and cassette spacing being the other two, almost all gruppo mfr's will work interchangably.

should debut about the same time we see Vodka Joe

You lost me. But I get the gist, and good to know. Too bad I'm too stuck up to mix and match my own bikes. My girlfriend's however...
