Campy Compatible Cranks

Help! I am trying to find some Campy Chorus BB compatible cranks that will allow me to run something smaller than a 39 on the inside. I have looked at the FSA Carbon Compact Pro, but I would have to by their Isis BB as well. My Cramerotti is Italian threaded and the 70mm Italian threaded version of their BB is 118mm, I need someting around 102mm. I have searched high and low and just thought I would look to all the vast knowledge in this forum.

it doesn't exist. if you run a chorus bb, then you have to run a campy crank, and that means you have a 135 mm bcd, which means nothing smaller than 39t. if you want something smaller than 39t, then you're going to have to get a new crankset and bb. period.

I pretty much realized that. I was just looking for something cheaper than the FSA. Replacing the bottom bracket is not an issue. If it has to be it has to be.

How much smaller do you want to go? TA does make 135BCD rings, only down to 39 for the inner, but in 48 for the outer for a standard cross setup. Cyclocrossworld.com has them.

You could use the Ritchey pro cross crank.. or standard FSA crank and not the carbon one. If you don't mind buying a new BB any cross crank really will do.

I probably wasn't to clear in my first post. Right now I have a 39/50 on the front and a 13/26 on the back. For most shorter hills this is fine, even steeper ones. The long 2 mile grades are killing me at the end. I realize that is not the norm for races, but I do use my cross bike to ride the dirt roads and some of the MTB trails. I would like to get down to a 36/50. That is the limit of my front deralliur. Either that or put a med cage Centaur deralliur on the rear and go to 13/28 cassette. Anybody have an opinion on which way to go. I am also confused about the "any cross chainring" thing. I thought the Campy stuff was particular about what chainrings and cassettes were used.
Thanks

try truvativ if you're running 9 speed.

Perhaps a dumb question, but can I use Campagnolo chain, rear derailleur, front derailleur and cassette with Shimano crankset and BB?

If, so: will a Campagnolo 9-speed chain work with Shimano XT blades? Will a Campagnolo 10-speed chain work with Shimano XT blades?

Thanks in advance,
Timo

You probably wont save much money over Campy, but Specialities-TA make beautifull cranks in a range of useful BCDs, including a 110mm double, ideal for CX. In addition, you can have them in any length from 50 to 85 ( or some such).
