SRAM Force 1 1x11 Speed Cyclocross ChainsetThe SRAM Force 1 Single Speed Cyclocross Chainset is a gamechanger. This chainset has combined all the benefits of SRAM's Force 22 road with SRAM's MTB (mountain bike) technology, X-Sync™, ensuring this chainset is reliable, durable and efficient, whatever the trail brings. The SRAM Force CX1 crankset brings to cyclocross a game-changing upgrade in performance and reliability by combining the durability, simplicity, and efficiency of Srams’s Force 22 road combined with their MTB 1X technology, X-Sync™.RAM X-Sync™ 1X 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.Features:Arm Material: Carbon arms with forged Aluminium removable spiderTechnologies: X-Sync™, Hidden Bolt configurationFinish: Natural carbon armsWeight: 679g (172.5mm, no BB)Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features updated 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11-Speed drivetrainsX-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grimeDUB™ Technology: The 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, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performanceBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
