Happy Accident Shimergo gravel grinder Campagnolo Centaur Veloce Athena Record Shimano Ultegra Dura-Ace Tiagra 105
One of these things is not like the others.

Look closely at the above photo. Notice anything out of the ordinary? I’ll give you a hint–that’s a Shimano 10-speed cassette playing nicely with an otherwise all-Campagnolo drivetrain. Big deal, you say. Shimergo setups have been around for years, and lots of folks use those methods to mix-and-match Campagnolo and Shimano drivetrain bits. In this case, however, I didn’t rely on alternate cable routing or spacer swapping to get everything to work. It just worked.

I stumbled across this particular combination completely by accident. I was swapping tires on a couple of bikes, and mistakenly installed a Shimano-compatible wheel in my Campy-equipped bike. It shifted so well in the stand that I didn’t even catch my error until it came time to mount the other wheel on the bike with with the Shimano drivetrain.

While internet message boards are littered with posts declaring compatibility between Campagnolo and Shimano 10-speed components, I’ve always been skeptical of those claims. I have successfully used the N-2 method (e.g. Campy 10-speed shifters with 8-speed Shimano cassette), but I’ve never been able to get a 1:1 combo to work consistently and reliably. This setup, however, shifted as smoothly as the homogeneous systems on both bikes.

On paper, this particular combination shouldn’t have worked as well as it did. I fully expected the shifting to suffer at the extreme ends of the cassette, but I never missed a beat, err, shift. By no means did I baby my shifting, either–especially when trying to match some much-stronger riders’ pace (which ultimately resulted in two Strava PRs). Try as I might, I couldn’t force a mis-shift, and believe me, I definitely tried.

For the curious gear-heads out there, below are the components that comprised this setup:

It’s interesting to note that every one of those parts has seen plenty of miles on their dedicated systems before being thrown into the Shimergo mix. I plan on upgrading the cassette to an Ultegra-level model (to avoid gouging the freehub’s alloy splines), and I’m curious to see if introducing a brand-new component spoils the system’s shifting.

Stay tuned…
