    Convert 9-speed Ergo shifter to 10-speed

    I've searched this site and Campyonly.com, and have scoured Google, but I haven't been able to nail down precisely which parts are required to convert a post-2000 Ergo shifter (Centaur) from 9-speed to 10-speed. Some say it's a simple operation involving the replacement of just the index gear, while others mention other parts that need to be replaced, such as a cam.

    Would anyone be able to answer this definitively?

    Why not compare the schematics and them decide what you need. I have never heard tell of anyone attempting such a thing. Lp

    Take a look at the spare parts document from Campagnolo (opens as PDF).

    The parts list and diagram for the Centaur brifter is on page 33. There, it appears that three parts are different between the 9-speed and 10-speed models: the shifter body and what looks like two shifting disc/cam.

    Try Rodd at Brandford. Check his website, it can be done http://branfordbike.com/page.cfm?pageID=63

    Thanks for that link! In cross referencing it to the page at the Branford site devoted to Ergo levers (Campagnolo Ergo Lever Parts), it looks like two of those parts are indeed different for the 9 and 10-speed, but even though the body appears to be different for 9 and 10-speed according to the Campy specs, Branford only sells one body.

    I'm going to go out on a limb here and guess that the body doesn't need to be changed. So basically it looks like two parts need changing:

    1. Index gear (Campy part #EC-RE061)
    2. Ratchet ring (Campy part #EC-RE062)

    Here's the pertinent page for that link (Daytona is the old name for Centaur, for those not in the know doing searches for this info in the future):


    Does this look somewhat definitive? By the way, Branford apparently does these conversions (Rebuilding Campagnolo Ergo Levers) for $60 labour plus the cost of parts, so this isn't something that is unheard of at all.

    Price the index gear and rachet ring, plus g-springs, then compare that to the price of 2009 Centaur or Veloce shifters in the $100-170 range. With the new levers you get a cable set worth about $40 and new brakes hoods worth another $30-35. It makes the new shifters look really cheap.

    The new shifters offer better ergonomics and not g-springs to wear out. After trying the 2009 Centaur, I sold off all of my old Record levers and I won't be messing the old ones anymore. The new design should rarely need maintenance, but if a repair is required, it's a lot easier to do. I've had the new shifters apart and found them much easier to disassemble and reassemble.
