SRAM Force DUB 12 Speed ChainsetFeaturing high-quality carbon crank arms, this 12 speed road bike chainset offers an excellent balance of strength, durability and low weight performance. SRAM has also equipped this model with two aluminium chainrings that are specifically designed for road cyclists who want more range and closer steps between gears. It offers smaller chainrings with a consistent 13-tooth gap between size variants, delivering smooth, accurate and dependable shifting for the modern rider. Always find the sweet spot.Road Chainset with DUB TechnologyThe relationship between the bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.X-Range GearingToday's drop bar bikes are faster and more capable. Riders want a bike with the wide range gearing to match their wide range of cycling pursuits. But, range is only one half of the equation; they also want a drivetrain that offers the right gear for any situation.X-Range achieves wider range and tighter jumps by going to a 12-speed cassette, but also by moving some of the gear range from the front of the drivetrain to the back. SRAM employed smaller chainrings with a consistent 13T difference, while giving the cassettes a 10T-start for wider range (up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to get to the right cadence with fewer compensation shifts in the rear. Fewer, faster front shifts make it easier for you to find the right gear, and that's a distinct performance advantage relative to traditional drivetrains.Features: Crank Arms Material: Carbon Chainring Material: Aluminium Use: Road Speed: 12 speed Number of Chainrings: 2 Tooth Count: 48/35T BCD: 107 Chainline: 45.0mm Bottom Bracket Spindle Interface: DUB Bottom Bracket Compatibility: All SRAM Road DUB BBs (bottom bracket sold separately)Technologies: X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear.

Shimano Dura-Ace R9100 11 Speed Road Double ChainsetThe Shimano Dura-Ace R9100 11 Speed Road Double Chainset boasts Shimano's well-known 4-arm hollow spider that is constructed from hollow-forged aluminium. This chainset has been completely redesigned to ensure it boasts the best combination of lightweight and rigid construction. The chainset has been adapted by Shimano to work with disc brake road bikes that have a 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. Although the crank arms and spider arms are bigger, this increases overall stiffness, and the chainset has dropped 7g of weight since its previous edition.The Double version offered here comes in numerous gear combinations to best suit each individual riders needs.Please note: A bottom bracket is NOT included.Features:Enhanced design saves 7g while maintaining rigidityIconic 4-arm construction maintains high rigidity and reduces weightOptimised crank arm design strengthens key stress zonesNew chainring tooth profile is adapted for race bike specific disc brake systemsAccommodates shorter chainstays (410mm) with 135mm OLD rear spacingHollowglide chainring construction maintains smooth shifting whilst reducing weight and increasing stiffnessWeight: 621g (53.39T)A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight of the Shimano Dura Ace R9100 chainset has dropped by 7g over the previous edition of Dura-Ace. Shimano has adapted the crankset to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The double version offered here comes in numerous gear combinations to best suit each individual rider's needs. Please note: Bottom bracket is not included.
Powering you from trail to trail with ease, this brilliant model features a tough aluminium crankarm construction with Hollowtech II technology. This means you'll benefit from its superior strength to weight ratio as you navigate across the woodland with amazing torque power and dominance. Giving you exceptional drivetrain efficiency, this fantastic version is also equipped with a 51.8mm chain line and can be converted between 1x12 speed and 2x12 speed using 38-28T chainrings. This means you can customise it to suit your specific riding style, discipline and the terrain conditions for a more rider-tuned experience.
Already a legend in its time, the SRAM Red Exogram Crankset is now available with refreshed graphics to compliment SRAM RED eTap components. The SRAM Red Exogram crankset features a completely hollow construction all the way to the spider. It's hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. As always for seamless, flawless performance and Yaw compatibility, the chainset has been equipped with X-GlideR chainrings. The chainrings are designed for an optimised shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimised performance.Arm Material: CarbonChainring Material: AluminiumBottom Bracket: GXP (Not Included)Weight: 609g
