SRAM Force 22 11 Speed Road ShiftersThe new SRAM Force 22 ErgoDynamic Shifters were modeled after the best in class comfort of SRAM RED, and represent the most advanced thinking yet on perfecting the interface between rider and bike.Everything received the same detail, including the transition between handlebar and hoods, the grip texture, finger wrap, and the separate interfaces with both the shifter and brake lever. The understated black finish makes it look fast and a perfect match for any machine.“SRAM call this 'True 22' because you can cross chain with their system - you can run the chain on the larger chainring and the largest sprocket, and the smaller chainring and the smallest sprocket...whereas Shimano and Campagnolo tell you specifically not to do this.” - Road CCFeatures:Incredibly light weight at the bars, improving handling and control, at 307 gramsErgoFit textured body improves grip and finger wrap with reduced diameter, providing better control, and a better transition to the barIndividual Reach Adjust of brake and shift lever, now easier to access and uses a standard hex key, puts the controls exactly where you want themLarger ErgoBlade lever improves shifting from the dropsDoubleTap technology delivers both shifts from the single leverZeroLoss shifting, shifts engage immediatelyNew clamp allows better fit and adjustment for modern carbon and ergo barsWeight: 307g (pair)Speeds: 2 (Front) & 11 (Rear)Compatibility: SRAM RED 22 & Force 22 Yaw Front Derailleurs, Exact Actuation Rear DerailleursTechnology Highlight(s): DoubleTap, ErgoDynamics, ZeroLossMaterial: Carbon Brake Lever, Aluminum Shift Lever, Textured Hood CoversDoubleTap: DoubleTap technology makes the leap to the flatbar 9 and 10-speed bikes, delivering smooth up and down shifts are lightning fast. The shift lever is adjustable for quick customization and the gear indicator is easy to see for quick referenceErgoDynamics: It consists of three separate elements to significantly improve your riding experience on SRAM DoubleTap controls. The brake lever is slightly longer than previous DoubleTap road controls to enhance the reach from the drops. The independent reach adjust features on the brake and shift levers are easier to access to quickly adjust for every hand size. Finally, the shape of the hoods has been completely redesigned with a smaller diameter and higher top shape to increase the rider's control and improve finger wrapYaw: The front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new RED crankset and chainrings, delivers an unmatched performance advantage in front shiftingZero Loss: Zero- Loss simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle-ground where you're waiting for the shift to come. Gear changes are instant and preciseBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The battery (sold separately) is shared with other AXS and eTap components, so can be swapped if needed and lasts between 20-30 hours of riding between charges.
SRAM's Eagle drivetrains set the benchmark for mountain bike drivetrains and now that same technology is now available at even more affordable level thanks the new NX Eagle DUB groupset. Using all the technology crammed into their higher-end groupsets, NX Eagle sets a new standard for performance and value for money.11-50t cassette provides massive gear range and fits on regular freehub bodyForged aluminium cranks are strong & incredibly stiff while steel X-Sync 2 chainring provides excellent chain retentionRear derailleur features a Type 3 clutch to provide perfect chain retention and smooth shiftingErgonomically designed trigger shifter shifts between gears seamlessly, even under loadSmooth shifting & highly durable chain with cutting-edge Flow Link designSuitable for bikes with 135/142mm rear axle spacingThe centrepiece of SRAM's Eagle drivetrains are the 12-speed cassettes, and the PG-1230 Eagle Cassette forms the centrepiece of the NX Eagle groupset, by providing the same wall climbing 50t bottom cog as the other groupsets, while the use of an 11t top cog means the cassette fits on a regular 8/9/10 speed splined freehub, meaning lower cost and better compatibility. Based around SRAM's DUB 28.99 axle standard, the NX Eagle DUB crankset features 6000-series forged aluminium arms that are both strong, stiff and lightweight and when used in conjunction with SRAM's DUB bottom brackets provide a smoother running and more durable system. The DUB system replaces SRAM's previous GXP and BB30 crank and bottom bracket systems to provide improved durability, better compatibility and a stiffer, stronger and lighter product. DUB cranks can be used with any existing bottom bracket standard when used with the appropriate DUB bottom bracket. Performance benefits aside, it also means your crank is future proofed in case you happen to swap your frame. SRAM's X-Sync 2 chainrings set the standard when the design was first released alongside the XX1 and X01 Eagle drivetrains and the NX Eagle DUB crankset uses a more durable steel version that uses the same unique hooked tooth profile that tenaciously holds the chain in place as well as improving durability of the chainring and chain.The NX Eagle Rear Derailleur features SRAM's X-Actuation technology which has been developed specifically for SRAM 1x drivetrains to ensure that shifting remains sharp, smooth and consistent across the entire cassette. The NX Eagle Trigger shifter uses the same ergonomic design as SRAM's higher end shifters and carries over many of their features, including Zero Loss to provide instant and responsive shifting as well as being MatchMaker X compatible, so it can be easily synced with SRAM brake levers to leave a clean, uncluttered cockpit. The NX Eagle Trigger Shifter also features a unique cover for the gear cable, so you can easily change the gear cable without having to dismantle the shifter cover, making cable changes a breeze. Using the same design and manufacturing techniques as SRAM's higher end Eagle chains, the NX Eagle Chain uses a highly durable solid pin construction and clever link profile to provide precise and slick shifting under even the harshest conditions. The unique profile also provides significantly reduced wear on Eagle cassettes and chainrings, massively extending the usable life of your drivetrain. SRAM's PowerLock quick links also make installation and removal a breeze. SRAM's NX Eagle DUB Groupset may cost a fraction of their higher end groupsets, but the performance is still exemplary and it packs an almighty punch without putting too big of a dent in your wallet. Wide range 1x drivetrains have never been so attainable thanks to NX Eagle.

X-Sync: SRAM X-SYNC chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. Orbit: Orbit technology is an innovative form of derailleur motion control. It utilises silicon fluid as part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch system, Orbit technology places no additional resistance on the rear derailleur's spring when under slow or light movement. This means easier shifting and rear wheel removal. And while riding, the fluid damper reduces chain bounce. It's rock-solid reliability for both 1x and 2x systems.Manufacturer's Part Numbers: 00.7518.121.001 Grey Short Cage Max 33t 00.7518.136.000 Grey Medium Cage Max 36tBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

DoubleTap handles up- and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars..DoubleTap® uses two pawls, one for holding the ratchet wheel, and one for transporting it up and down through the gear change. The pawls are arranged in a way so that they can leapfrog each other depending on how far, and with how much pressure, you push the shift lever..With short, rapid taps the transport pawl (04) moves the ratchet wheel (02) up through the shifting range. Downshifting comes via a longer sweep of the lever (in the same inward direction you upshift, but to an ergonomically maximized 15° angle) with the holding pawl (03) and the transport pawl leapfrogging each other quickly and smoothly..Location, Location, Location: DoubleTap’s one-motion unidirectional levers (05) work flawlessly no matter what position you’re shifting from. Its double-articulated design (01), which is completely separate from the brake pivot, is easily engaged from the hoods or the drops..Unlike all other forward controls, DoubleTap® also lets you pull the shift lever in against the bars so you can upshift while sprinting or attacking without giving up a firm grip. On DoubleTap® controls, the brake and shift levers are completely independent, each operating with their own pivot points. This not only allows for the multiposition functionality, it also eliminates the risk of engaging brakes or shifters unintentionally—an unfortunate side effect of other shift/brake lever designs..EXACT ACTUATION™When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting.
