Slotting in just below the excellent Force groupset is the updated Rival group which now offers 22 gears, but unlike the Force group it is constructed from aluminium to help keep the price down. Featuring super-stiff, 5mm 7075-T6 CNC-machined aluminum chainrings, the crank utilizes the same X-Glide R precision-shifting technology pioneered on SRAM's revolutionary XX mountain groupset. Shifting is not just smooth, it's lightning-fast, with no "shift lag" as you wait for the chain to connect with the ramp pins on upshifts. The aluminum arms join a machined alloy spider, creating a tremendously stiff package that doesn't weigh all that much more than its carbon equivalents. The Rival 22 crankset, like all SRAM 22-speed drivetrain cranks, is designed to work with any of the company's Yaw front derailleurs, which rotates the cage as it shifts, improving shifting precision and eliminating the need for trimming to avoid chain contact with the cage's rear edges. The crankset, chain, and front derailleur are designed to work in unison, and when properly configured, it's one of the finest drivetrains at any price point.Chainring Sets: 52/36TBB30 Bearings Not Included

Campagnolo Centaur Ultra Torque 2x11 Speed ChainsetThe Campagnolo Centaur Ultra Torque chainset brings top-end features and technologies to the masses. Featuring the same four-arm spider as seen on Campagnolo's "Super Record" model, the Centaur has the extra strength where it's most needed, ensuring excellent rigidity for efficient gear shifts, sprinting, and climbing. It's also very versatile, as if you want to change from a 50/34t to a 53/36t or vice-versa, there's no need to change the entyre chainset as the spider is compatible with either chainring combination.Smooth PerformanceThe Centaur's chainrings have a special anti-friction coating to encourage smooth chain operation. The chainrings also feature Campagnolo's "MPS" technology, which enables quick and accurate shifts no matter how hard your pushing and in all weather conditions. Also, thanks to the use of the "Ultra Torque" bottom bracket system, you'll enjoy consistent, rigid performance and optimised power transfer.Features:Material: Aluminium (crank arms/chainrings), Steel (integrated axle)Speed: 2x11Bolt Circle: 112/145mmBottom bracket cups not includedRecommended Chain: Campagnolo 11-speedAxle Profile: Ultra-Torque - integrated axleWeight: Approx. 875g (170mm crank arm length without BB cups)Technologies: MPS (Micro Precision Shifting System): Optimised design of the up-shift and down-shift zones and of the profile of the teeth - enables fast and precise shifting in all types of conditions. 8 chain upshifting areas and 2 chain downshifting areas result in faster and more precise shifting, even under stress. Ultra Torque System: Six years after its introduction, this system is still considered the best performing chainset spindle in terms of stiffness, low weight and efficiency of power transmission. Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective chainset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Furthermore, despite the narrow side profile, Campagnolo has been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter.Buy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Shimano 105 chainsets are known the world over for their reliability and performance. Having been refined from the previous version the 105 R7100 furthers this reputation. For this edition, Shimano have carefully engineered the R7100 crankset to offer an excellent balance between stiffness, strength, weight, as well as rotational performance. The result is a chainset equally suited to big days riding in the mountains, as it is fast bunch rides. Trickledown Performance Thanks to the benefit of trickle-down technology, the difference in quality between a 105 chainset and the more premium Dura-Ace or Ultegra versions is closer than ever. Now, with the addition of Di2 to the 105 R7150, the decision to purchase anything more expensive is even less justifiable. That is, of course, unless you simply want to spend the money on the flashiest tech around! All The Tech As with any product from the Japanese component giants, the FC-R7100 chainset employs some of the company’s top tech. Shimano’s famed Hollowglide technology means the outer chainring is hollow, to reduce weight but is engineered to do so without diminishing strength. This is the same technology employed on a number of the brand’s cranksets, including the top-tier models: Dura-Ace and Ultegra. Additionally, Hollowtech II technology is used to keep weight to a minimum, while maintaining strength and stiffness. The result is a crankset that won’t leave you bogged down on a climb and ensures maximum power transfer from your legs to forward motion. Again, this is the same technology employed in Shimano’s top-of-the-range models. Whether it’s the perfect chainset for big days out on the saddle or something for racing your local criterium the 105 R7100 is the perfect option, particularly for those slooking at a more affordable price range. It offers smooth shifting, an excellent balance between weight and stiffness, and won’t break the bank. Product Features: The Hollowglide structure reduces weight but maintains strength Crank Arm Lengths: 160, 165, 170, 172.5 and 175mm Gear Combination: 50-34T Q-factor: 148mm Weight: 765.6g (50T, 172.5)
