SRAM Force1 12 Speed Chainset Chainsets
  • £199.99
  • RRP £225.00
  • Saving you £11

This race-ready 12 speed chainset features a carbon crankarm build, which means that riders will enjoy increased stiffness when climbing and an overall lower weight when accelerating on the flat. Its impressive strength to weight ratio is further enhanced thanks to its single X-SYNC aluminium chainring that provides exceptional durability and longevity as you tackle whatever the course throws at you. Coming equipped with X-SYNC technology, this model's chainring uses its wide/narrow tooth profile to deliver maximum chain control for an extra confidence boost on race day. One final highlight is its kitted out with a DUB compatible spindle interface for a simpler, stiffer, and more secure connection between your chainring, cranks and bottom bracket.  SRAM originated the 1x drivetrain, and the SRAM Force 1 crankset evolves the innovation. It's lighter, stronger and simpler—non-aero chainrings can now be installed with a single tool. For cross, time trial (TT), triathalon and crits, this is the king of 1x. - Single-ring drivetrain simplifies functionality and reduces weight - 48t variant has direct mount aero chainrings for better aerodynamics - Non-aero chainrings can be installed with a single tool, making gearing changes a breeze - SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control - DUB™ bottom bracket adds durability and simplicity - Can be upgraded to a power meter Technologies: X-SYNC: SRAM 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. Accept no imitation. DUB: The relationship between 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. Bottom bracket sold separately.

Shimano GRX 815 Di2 2x11 Speed ShifterThis sensational shifter is specially developed to get you through the gravel and mud with stress-free operation. It features some of the most sought-after technologies including the revolutionary Di2 shifting system which gives you instant, accurate and lightning-fast shifts. Improve your grip and confidence on rough surfaces and descents thanks to its raised hood which prevents slipping. This is an ideal upgrade for riders who want to enjoy higher braking efficiency with game-changing electronic technologies. Features:   Use: Gravel, Road     Speed: 11 speed   Reach Adjust: Tooled  Type: Dual control lever Oil: Mineral oil  Recommended Brake Caliper: BR-RX810Technologies: Di2: The revolutionary Di2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. Di2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With Di2, you are in complete control.  E-Tube: The E-Tube platform's “Plug & play” and D-Fly wireless connections make it easier than ever to check the system's status and apply customized settings to Di2 and Shimano Steps components with a PC, tablet or smartphone. SEIS: A technological innovation of the computerised shifting system based on the Di2 concept with which is called, the SEIS (Shimano Electronic Intelligent System). The SEIS innovative shift technology is still based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobblestone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to the mechanical Dual Control Lever, so you don't need to re-program your mind for the SEIS. Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.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.
