2002 Trek 5200 DA components, 2002 Trek 2300 Ultegra components
Anyone tried using a 7800 10 speed crank with 9 speed chain. What I want to know basically is can I use a Shimano 7800 crankset with the rest of my Dura-Ace 9 speed drivetrain. I currently using the Shimano7800 10 speed front/rear derailleurs with Dura-Ace 9 speed cassette,crank and chain. Just wondering anyone had experience with the 10 speed crank and 9 speed chain combo. I looked on Sheldon's site, but could not see where crank and chain combo was addressed. Thanks for input in advance.
