In another thread I experessed some confusion about whether the FSA Compact Crank will work with Shimano 10 speed. The description for the Shimano version of the crank specifically says 9 speed.

I sent an email to FSA and they replied with a one liner saying the crank was compatible with both 9 and 10 speed.

Can someone help me understand this? I thought the 9 and 10 speed Shimano cranks were incompatible because of the narrower chain and tighter chain ring spacing. Anyone out there play with these toys yet?
