The problem is that none of the current generation of smart, wheel-off trainers support Campy 10. Wahoo supported it up to 2016 but no longer with the newer ones. I think since Campy 11 works with Shimano they just dropped it as only us old folk are still using 10. As for buying another road bike, my wife would throw me out of the house! We already have 9 bikes in the house. But I do have a friction shifted classic Campy SR bike that could go on the trainer and with friction shifting it doesn't matter what the spacing is. I'd have to get a new saddle for it as it has the original from the 1980s still. I don't know what they were thinking back then, but they weren't taking into consideration the shape of one's arse.
In any case I'm looking forward to having a smart trainer this winter. As much as I could follow along with a power meter on a dumb trainer I still felt there was something missing. I'll have to make sure I have FTP/4DP numbers set correctly so it doesn't kill me.
