Campy 10 spd. chainring really necessary?(4 posts)

I'm currently in the process of upgrading to 10 speed (all chorus). My question is: how necessary is it to swap to the 10 speed big ring (from the 7-8-9 speed ring). I mean, c'mon, the only difference is something like 0.03mm milled off the back of the mounting tabs. I would guess that this is done to quicken up the shifting, but is it *necessary*? Will my chain lodge between the rings if I don't? Doesn't seem like it would. I'll probably just go ahead and try it and see, but I was wondering if anyone here has tried.

Do a search..... I seem to recall seeing this issue posted previously.

If I remember correctly, there was a comment about a chain wedge "event" so there may be a good reason to upping for the new cranks/chainring. You should also email branford and get their opinion. The fellow that runs that site is quite good re these C8-9-10 conversion issues.

I have a friend who used a Shimano crank (9spd) to get a shorter crank length and it works fine.
shimano rings have closer spacing...C-40

Campy didn't alter the ring spacing when they changed from 8 to 9 speed, so essentially you're trying to use 8 speed ring spacing with a much narrower 10 speed chain.

Shimano moved the little ring closer to the big ring on their 9 speed cranks. That's why it works successfully with 10 speed.

It would certainly be best to get the campy 10 speed chainring.
