110/74 cranks and 9 speed chain?

If I use a 110/74 triple crank with a 9 speed Campy cassette and chain, would there be any problem
with the chain wedging between the rings? In other words, are there some 110/74 cranksets which work
with 7 or 8 speed chains, but are not meant for 9 speed chains?

It's the chainrings and not the crankset that make the difference. I replaced the worn out 39t inner
chainring on a current model Dura-Ace crankset with an older chainring that pre-dated 9s
drivechains, and had several instances where the chain skated between the two chainrings when
shifting off the big ring. When I compared the older chainring to the Dura-Ace, I noticed that the
teeth on the Dura-Ace ring were closer to the outer face of the chainring to prevent this problem.

TA (amongst others) sell 110BCD chainrings that specifically say they are compatible with 9s.

I use a SRAM/Sachs PC69, 9 spd chain with standard 8 spd. 110/74 rings with no issues on a
drivetrain consisting of: Campy Centaur shifters, R derailer, Wheels Manufacturing 9 spd. cassette.

I use SRAM 9 spd chain with 8 spd rings and 9 spd other stuff - no problems. B

No..just ensure you ease up a bit on pedal pressure when you come off the rings to a smaller ring,
which is what ya oughtta do anyway.

I have a Sugino XD500 triple (110/74), which I believe has 8-speed spacing. The rest of my
drivetrain is 9-speed (Shimano cassette and SRAM chain). No problem.

I have an 8 speed 110 bcd double on a 9 speed system, and occasionally get the same chain skating in
between the rings problem. When it happens (which is not all that often) it is only a problem when
I'm shifting under pressure (which I shouldn't have done anyways).
