Hey Bryan, glad to hear you found some levers. I've got a bike that has 10 speed Campy levers running a 9 speed Shimano cassette, funky routing around the clamp, and it shifts just fine.
I also have a bike with 10 speed Campy levers running a 10 speed Shimano cassette with a Shiftmate #3, and it is also great. I wouldn't bother with the Shiftmate to go 10sp Campy to 9sp Shimano, to be honest. Just run the funky routing and it'll go. If you wanted to still run 10 speed I can highly recommend the Shiftmate, though. Anyway, have fun. ~Oliver On Friday, July 25, 2025 at 3:15:03 PM UTC-4 Bryan Dalik wrote: > UPDATE!
