SRAM's 10-speed drivetrain has been in production for a few years, but until now, there's been no option for its renowned twist shifters? unless you're happy with nine rear cogs. Famous for their low weight, ability to shift multiple gears at once, and dependability, SRAM's twist shifters created a stir when first introduced, and were essential to the company's early success. Those positive traits and vibrant history continue with the introduction of the X0 2x10 Grip Shifters.Early Grip Shift blindsided the mountain bike market in the early 90s because it offered a much simpler, faster, and lighter weight way of changing gears. Grip Shift got the job done with few moving parts, compared to trigger shifters, which used as many as thirty individual components. Racers were quick to take advantage of the faster gear changes and lower weight. Soon Grip Shift was enjoying both downhill and cross country podiums under notable racers like Greg Herbold and Ned Overend. Jump ahead to today, and the new X0 Silver 2x10 Grip Shifter Set has already proven itself on the race circuit with a 2011 XC World Championship under its belt. Developed for use in the BlackBox racing program, the first 10-Speed Grip Shifters were successfully campaigned under Jaroslav Kulhavy. What SRAM learned racing those prototypes has directly enhanced the production versions.The X0 foregoes carbon in favor of aluminum to keep its price lower than the higher-end XX Twisters. It still rolls on ball bearings ? a first for SRAM twist shifters. This provides longer life than bushings, and reduces the effort needed to change gears. Speaking of action, these shifters use SRAM's 1:1 Actuation ratio. For every unit of cable pulled, the derailleur moves the same amount. Wide tolerances ensure consistency in every condition from dry and dusty, to sloppy mud, to frozen fat-bike adventures. 1:1 Actuation also eases setup, with simple adjustment from the shifters' barrel adjusters. Another key upgrade are the integrated lock on grips, which help prevent dreaded throttle grip, something that cursed small rubber grips of early Grip Shift. The integrated lock on grips hide the clamp to provide a seamless ergonomic transition from grip to shifter.The X0 2x10 Grip Shifters is compatible with SRAM's 10-Speed mountain and road rear derailleurs, opening up possibilities for touring or commuting applications. However, it's only compatible with SRAM's 2x10 front derailleurs.
Strengths: SPEED, simplicity, light weight, being able to shift All gears,up or down, clean looks
Weaknesses: Pricey, outer locking on grip is raised
Bottom Line:
I was very surprised how fast the front shifter works on 2 ring front crank.It takes maybe a 1/4 inch to rotate the grip.
The best thing I like about the shifters is the ability to shift the whole cassette range ,up or down,which is very useful on steep up and down transitions.
I would like to try a clutch type 2 rear der with this setup
After being a loyal grip shift user for many years, I was excited when they came out with a 10 speed twister. My old 9 speed was rock solid reliable. The new one is $$$ P.O.S. Broke after 2 rides. They took a great design and screwed it all up. The barrel adjuster is made from egg shell thin plastic and recycled beer cans (metal cover). EPIC design fail. Heading back to Shimano. Don't waste your $$$.
