I am wanting to upgrade my olmo to post 2001 campy 10 speed. Preferably using 2009/2010 Centaur/Chorus Ergo's that retained the Ultra Shift.

My question is, how important is it to have to have "10 speed" cranks when using these Ergos? I actually kind of like the look of the cranks that are currently on the bike (which I think are 80's C-record).

These are my current cranks:



Would they work with 10 speed ergo's?

In spite of the nice reference Robbie provided, they will work, with a caveat. The chain is narrow enough to drop between the rings, and is not ideal. A lot depends on the skill of the operator. You could go to Campy Chorus/Record 10 spd alloy cranks, and not look back. I think they even look better than C-Record, thinner arms and still a hidden fifth.



I use Campy chains, but have heard good things about KMC, no experience with SRAM on Campy, Robbie's link says not so hot.

I run 10s on (2) bikes with Athena 8s cranks FWIW...

I laid a 10spd double crank set up against a 9speed double (I have both) and the rings lined up perfectly between the two.

I wonder if this is true for mine as well. I am guessing that mine are really 7 or 8 speed.

And one more question-- is there any significant difference in the chain rings? Are the 10 speed rings significantly skinnier than the older ones?

I think those Record 10 speed cranks look awesome. I have watched a couple Record 10 speed cranks on Ebay, and they don't seem to go for ridiculous amounts. I may just have to do that.

But if I was going to buy new campy cranks, should I consider getting the new style with outboard bearings? As I recall you have those on one of your bikes.
