Things I Like: da Vinci Custom SRAM Derailleur

There are a number of ways to mix-and-match Campagnolo Ergpower levers with an otherwise-Shimano drivetrain.  Options include from alternate cable routing, conversion cassettes, and cable-pull adapters.  I’ve experimented with several of those methods, but my favorite way to pair Ergopower levers with Shimano running gear is da Vinci’s custom SRAM derailleur.

Starting with a medium- or long-cage SRAM X9 derailleur, da Vinci replaces the stock cable guide with a special CNC-machined guide that allows the different brands’ components to play nicely in the same sandbox.  The derailleur is available in versions for 10-speed Campagnolo or 10-speed Shimano levers (both are compatible with Shimano or SRAM 9-speed cassettes).

Installing the custom SRAM derailleur is similar to installing any other modern derailleur (and takes less trial-and-error than cable-pull modifers or alternate routing)  The only real difference is that you’ll need to account for your particular shifter’s “extra” click.  On my bikes, I usually set them up so that the phantom click occurs after the shift to the largest cog.

The da Vinci derailleur controlled by 2nd-generation Centaur levers (with an 11-32 cassette).

Shifting with the da Vinci derailleur is spot on.  I’ve used the derailleurs successfully with 2nd- and 3rd-generation Ergopower levers, and both Shimano and SRAM 9-speed cassettes (with KMC, Shimano, and SRAM chains).  And because the standard SRAM X9 derailleur is targeted to mountain bikers, it can easily handle 32- and 34-tooth large cogs (and wraps plenty of chain for double- and triple-chainring cranks).

If you’re a Campy fan and you want wider-range gearing, compatibility with 135mm rear hubs, or the increased longevity from 9-speed cassettes and chains, the da Vinci custom is definitely worth considering.

  1. Nice write up. Just ordered my modified SRAM from Da Vinci today. Time to upgrade our original 7 spd gearing on our Santana Team Noventa and this seemed just the ticket to get us to 9 cogs while keeping the front derailleur trim options of Campy.
