Model/Year: 2010

Pros: shift so well. and super light carbon fiber. look BA as well.

Cons: price.

Recommendation: if you want perfect shifting then you got to drop some $$$. and they work so well with my shimano LX FD.

Pros: Crisp shifting, good color designs,

Cons: Cost is heavy

Recommendation: Excellent shifting when paired with X0 RD, push push easy to convert to from Shim LX and upwards with 2-way.

Pros: Shifters seem like dumb things to worry about but whenever I ride bikes without XO shifters... I miss them. They have great shifting response, they're hella light and work great with almost every drivetrain set-up. They're also sexy as sin.

Cons: They cost more than most people spend on their frames.

Recommendation: If you've got the money or know someone who does... buy 'em.

Pros: Crisp shifts, light weight and a nice break from XT/XTR. Fits well with Avid Brakes on the bars. Can adjust the shifter throw. Can get Shim 2-1 compatible units if need be.

Cons: No gear indicator...yep I got used to that on he Shim. Push-Push shifting..I did like the Push-Pull/Push Push option of the XTR

Recommendation: It's a great unit and when mated to the X.0 rd..it's perfect. INSTANT shift and easy to take a later shift in some cases...when you need it.

Pros: Positive shifts, adjustable lever. Light weight

Cons: Cost

Recommendation: A near perfect shifter highly adjustable allowing you to have it installed before or after the brake lever as well as adjusting the lever it self.
