Anyone know if zero loss exists on the 10 speed sram trigger shifters? and what the differences between the x7 x9 and x0 10 speed shifters are? I understand the 9 speed shifters differences are

9sp x7 matchmaker compatible top cap cable change
9sp x9 matchmaker compatible top cover removal cable change zero loss
9sp x0 matchmaker compatible top cover removal cable change zero loss adjustable lever position

10sp x7 matchmaker compatible top cap cable change
10sp x9 matchmaker compatible top cap cable change anything else??
10sp x0 matchmaker compatible top cover removal cable change adjustable lever position

Sorry for being such a geek but i really like the feel of my existing x9 shifters with zero loss over my mates x7.

Also the main sram site has been updated with the 2x10 stuff (instead of the sepearte 2x10 site) and some other stuff!
