Mavic 840 with Campagnolo

Cooker · May 20, 2013

Hi all,
I want to keep my new bike build all MAVIC but seeing as MAVIC never made brifters I have to resort to another brand. Being a euro lover the only alternative is Campag shifters.
I was wondering if a Mavic 840 indexing rear Mech will work with 10s Campagnolo shifters?
If not, why?
If it won't work with the newer 10S will it work with older Campag 8/9S shifters?

Cheers

What are you planning to use them for? An aerobar?

No, just normal Mavic 351 road bars.

Based on personal experience using 8sp cassettes with Shimano spacing, the Mavic 840 derailleur will work very well with 10-speed Campag Ergo levers.

I will be using a 10speed cassette campag spacing, with 10s Campag shifters.
Will the 840 rear mech work ok?
Parallelogram angles etc etc

How come a cassette with shimano spacing works when your using Campag shifters?

It's to do with the amount of cable pull per click compared to how far the mech moves - just so happens that 10s Campag will index a Shimano 8s system (I think there are some useful snippets on the CTC's website about this, pretty sure - as you might expect - that Sheldon Brown compiled something for his site too). Likewise 9s Campag and 7s Shimano, which I have on my touring bike. This came about in my case because I like the look and action of Ergo levers, not a big fan of Shimano STI levers. On the other hand, Shimano-compatible cassettes and hubs seem easier and cheaper to source so I mixed and matched!
