Is anyone running a single chainring setup with a campy 10 speed rear derailer? I am considering a FSA pro road crank with a spooky ring guard and 42 tooth TA ring with a Campy Chorus 10 speed rear derailer. Theoretically it should go, but it would be nice to know for sure.

So long as the TA ring is thin enough to run with the narrower Campy 10 chain, the rear won't care what brand of stuff is tugging at the front.

Just to make sure the chain & ring are compatible, I'd wrap the chain around the un-mounted ring to make sure it seats all the way down around the teeth. That way you can still get a refund on the ring if it's not going to work. Shouldn't be a problem, though.

If not, I know that does sell Campy-crank compatible chainring guards from a Czech company, though they may already be out of stock for the season.

I'm running a very similar setup, and it works great. I'm using an FSA Energy road crank, Spooky outer ring guard, Dura Ace 42 tooth chainring (and I've used a 44-tooth TA ring before on this setup as well), Chorus 10 speed cassette 13-29, Centaur rear der, Centaur 10 speed ergo levers.

The TA ring I had worked just as well, I switched to the Dura Ace because I wanted a 42 instead of a 44, and the Dura Ace was available at my LBS. BTW, the TA rings actually have printed on them "9/10 Speed" so there's definitely no issue there as far as working with the 10 speed chain. The only trick for me was getting a good chainline, which will depend on your frame. I tried to use an inner chainguard with this setup, but I couldn't get a good enough chainline without rubbing the inner guard on the chainstay. Instead, I'm using the Jump Stop chain watcher and it works flawlessly, while allowing me to adjust the chainline further in toward the frame.

Check the Campy website, but if I remember correctly, the Chorus rear deraileur will only accomodate a maximum 26-tooth rear cog. The Centaur will work with a 29 (which is nice to have when you only have a 42 up front). Good luck with your build.
