    Campagnolo Ergopower, 8-speed and later

    Looking to do some research on Ergopower shifting 8-speed and later. What are some of the critical years to pay attention to?

    1994 was the shift from pre-exadrive to exadrive spline pattern with a wide spline to align the cogs.
    My 1995 Mirage 8spd was retired because Exadrive cassettes are so hard to find. Miche make them in limitted sizes, available from specialist shops.

    What information are you actually looking for?

    The official Campagnolo web site - Bicycle Parts and Components Cycling has full info on the components inside the levers back to 1997 and we can provide a certain level of information by email but it depends first on what information is needed and second the reason it's required? We do run comprehensive technical training for professional mechanics which starts where most industry-recognised accreditations leave of ...

    1998 was the shift to the new rounded hood design, which is preferable to the old pointy-hood design because Campagnolo discontinued the small springs which eventually break on those apart from the G-springs.

    2000 ten cogs

    2001 and newer 9 speed shifters use the 10 speed derailleur geometry with its increased actuation ratio (tension adjustment on lower pivot).

    2007 - 2008 shifters at the Centaur level and below got the much maligned Escape mechanism that only shifts one cog smaller per lever actuation

    2009 brought us 11 cogs and Ultrashift, although early 2009 10 cog units have weak detents

    2010 was the last year of 10 cog Ulrashift

    2011 brought us PowerShift which is Escape with a catchy new name and the new Ultrashift hood shape
