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.

SRAM Force 22 BB30 11sp Road Double ChainsetThe new Force 22 chainset delivers an upgrade in performance by utilizin gunidirectional carbon in the crank arm matched to a forged alloy spider. The stunning X Glide R chainrings are optimized for use with the YAW Technology in the front derailleur, delivering seamless, flawless performance.It comes in fullsize and compact ratios and in multiple crank arm lengths.“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 CCX-GlideR Chainrings: The chainrings are designed for an optimized 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 optimized performance. Features:Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearanceStiffer X G lide R chainrings feature thicker construction, advanced shift timing pins and ramps, which are optimized for shifting with the Yaw Front DerailleurArm Material: Carbon/ Machined Alloy Chainring Material: Machined Alloy Compatibility: SRAM RED 22 & Force 22 Yaw Front Derailleurs, SRAM RED 22 & PC1170 chains Technology Highlight(s): XGlideRWeight: 697.4g (BB30 172.5mm 53x39 BB not included), 714.8g (GXP 172.5mm 53x39 BB not included)*Please note, Bottom Bracket is NOT included.Buy SRAM Force 22 Compact 11 Speed Chainset from Chain Reaction Cycles, the World's Largest Online Bike Store.
SRAM Red 1 AXS Road Power Meter ChainsetFeaturing two high-quality carbon crankarms, this power meter chainset is ready for training by delivering exceptional stiffness and strength without adding any unnecessary weight to your road bike. SRAM has also equipped this model with a single X-SYNC narrow/wide aluminium chainring for maximum chain control and precision as you beat your personal performance goals. With a power meter that delivers measurement readings that are accurate within +/-1.5% and aren't affected by climate conditions, you'll enjoy reliable results and performance data whatever the weather conditions. Coming complete with AXS wireless connectivity as well as renowned technologies such as DUB, DZERO, X-range and Exogram, this is a great choice of upgrade for reaching new goals and taking your training sessions up a notch.Road Bike Power Meter with AXS Wireless TechnologyAXS is SRAM's bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behaviour, personalise controls, get maintenance reminders, and update firmware.Bluetooth and ANT+ CompatibleWith SRAM's power measurement technology that uses Bluetooth Low Energy (BLE) and ANT+ connectivity, you'll have the technology to get real results. Your riding and training efforts deserve power measurement that reaches the highest standards of accuracy to help you reach personal records. Because without accurate data, you can't know if you are making the progress you're aiming for. Another highlight is the chainring can be easily changed without requiring recalibration of the power meter.
