Upgraded my X5 to XO and what a difference. I've always felt the Sram 1 to 1 ratio made their shifters superior but what ever makes "zero travel loss" work has upped the anti again. That and the ability to adjust the actual position of the shift levers to fit my hand convinced me the XO's are the best shifters I've ever used.
