I've been running a Shimano 600 Tri-color crank on my Ciocc. I love the way the 600 looks and performs, but last weekend during a century, the left arm came loose and is now trashed.

I'm now weighing the options for replacement. I don't really want to go with another square taper crank at this point.

Searching around I found the Shimano FC-6600 Ultegra cranks which look good to my eye.

A few questions:

• Can outboard bearings be mounted on a C&V frame?
• Can I mount the chain rings from my 8-speed system on these?
• Can I just run the narrower 10 speed rings?

Would like to hear from anyone running outboard cranks
