And its performance is just as good as when I started. I’ve spent just over one full year now riding Campagnolo Chorus 12. Campagnolo Chorus 2×12 all-road & gravel bike gruppo But while the newer 1x 13-speed Ekar is undeniably a huge advance, and shift off-road for the classic Italian drivetrain maker ( and I’ll get to that more), the capabilities of the slightly older 12-speed Chorus group cannot be ignored for mixed-surface riding from all-road to bikepacking touring. Reviewing a Campagnolo groupset for gravel riding these days, Chorus 2×12 isn’t the first model that pops into people’s heads.
