Dear Lennard,
Maybe this topic has been discussed, but I cannot seem to find it. I recently replaced my Campagnolo 10-speed chain on my Chorus 10-speed with a Dura-Ace chain at the advice of some local shop mechanics. I now seem to be having a bit of trouble shifting between the large and small chainring. Sometimes the chain seems to get somewhat stuck between the large and small chainring. I did remove my chainrings and reinstall them to clean them when I changed the chain, but all the marks are lined up as they should be, and the chainring bolts are tight. Have you heard any reports of using the Dura-Ace 10 chain on Campy 10 and these types of issues? I have a race this weekend and would like to replace the chain again if this is a known issue.
Jason
Dear Jason,
It sounds like, although you did not specifically say so, that you replaced the Campy 10-speed chain with a Dura-Ace 10-speed chain (as opposed to a Dura-Ace 9-speed chain). If that is indeed what you did, I definitely recommend against it for exactly the reasons you cite. The Shimano 10-speed chain is considerably narrower than the Campy 10-speed chain, while the Shimano 9-speed chain is close to the same width as the Campy 10-speed chain. I have successfully used a Dura-Ace 9-speed chain on a Campy 10-speed system with no problems, and I know lots of other people who have as well. Of course, Campagnolo recommends against using any chain other than its own 10-speed chain with its drivetrain.
