The XX designation is reserved for SRAM's top-line offerings and the XX Grip Shifters stays true to that. Using carbon fiber in place of the aluminum found on the X0 twisters, these 10-speed shifters are insanely light and pack the performance demanded by top riders. In fact, the XX Grip Shifters already have a World Championship under their belt. Developed for use in the BlackBox racing program, the first XX 10-Speed Grip Shifters were successfully campaigned under Jaroslav Kulhavy to a 2011 World Championship win. But, twist shifters aren?t new to the podium. Early Grip Shift blindsided the mountain bike market in the early 90's because it offered a much simpler, faster, and lighter weight way of changing gears. The original 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.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 XX Grip Shifter Set, and are helped along by a large dose of BlackBox tweaking.What SRAM learned from putting prototypes under Jaroslav Kulhavy has directly enhanced the production versions. The shifting mechanism rolls on ball bearings ? a first for SRAM twist shifters. This provides longer life than bushings, smooth operation, 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 the 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 XX Grip Shifters is only available as 2x10 and 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 dedicated SRAM 2x10 front derailleurs. The shifter set comes with a sealed Gore Ride-on low-friction cable system to provide long lasting performance.
Strengths: ~One of the lightest, fastest shifts you'll ever get
~Crisp ball bearing twist action, in three rows of bearings
~Lock-on 100mm grips included
~All metal detents, greatly reduces wear and vague shift engagement, often found on SRAM X0 9-speed twisters
Weaknesses: ~Expensive as HELL
~Flat spring "clicker" detent is fastened very poorly, to shifter body. Twist too fast and hard, often results in spring coming loose and jamming shifter up = BAD race finish results
~Carbon body cover is secured by only ONE ring - requiring precise installation and mounting
Yes, this is the world's first grip shifter to win a World Cup Championship/Olympic Gold Medal(Beijing 2008), under Specialized XC Pro, Jaroslav Kulhavy. Obviously, SRAM capitalized on those victories, to grossly OVERPRICE such a simple piece of machinery. Think about it - not much R&D is required to engineer three rows of tiny ball bearings and add one indexed shift detent, is there? As much as I love twisters I cannot fathom how SRAM can get away with such robbery. Ok, enough of the personal attacks...
The Achilles Heel of the XX twister, lies within the shifter body itself. There is a flat spring that has curved tabs which engage the ten metal detents. All this is regulated by a thin, long coil spring. The problem is when you are in a race situation and has to shift hard and fast - that flat piece of metal can come loose inside the shifter body and jam the entire shifter....or lodge itself where you can only get 3-4 useful gears. This is totally unacceptable for a $300 MSRP shift system. And, don't EVER try to take it apart yourself! Go straight to your LBS with purchase receipt in-hand(critical!) to have SRAM warranty this ASAP.
Treat this delicate part with caution and you will be rewarded with incredibly rapid shifts, in each direction. Where else can you dump all 10 gears on one twist? Nowhere, that's where!
I cannot thread a new cable inside the twister. Where does it enter? Unlike the older 9-speed - where the cable enters through a hole behind a rubber shield.....I see nothing inside the 10-speed version. SRAM website don't even have a service guide?Read More »
Anybody currently running the XO/XX SRAM Grip Shift. I'm thinking about buying some XO grip shifts, but trying to get some feedback before i do. They look much better than the old throttle shifters, and seem to mostly get good reviews(for few i can find online) by the people who ACTUALLY tried them. ... Read More »
Does anybody know how many clicks/trim are there in the latest SRAM XX and XO 2 x10 grip shifters? I am planning to upgrade to SRAM XX Grip shift and rear derailleur but thinking about using my current FSA K force light triple carbon crankset. I know the SRAM 2 x 10 thumb shifters are not compatible ... Read More »
