SRAM X1 Type 2.1 11-Speed Rear Derailleur
  • £195.00
  • RRP £217.00
  • Saving you £10

The SRAM X1 rear derailleur shares all of the same great technology as the more expensive X01 model but instead features an aluminium cage instead of carbon which adds a few more grams but also keeps the price down! Every detail of the 11-speed X1 X-Horizon rear derailleur is engineered for smooth, reliable shifting action-from the larger upper pulley offset to the 12-tooth X-SYNC pulley wheels. By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever. Roller Bearing Clutch rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain. With Roller Bearing Clutch technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

Box Three Prime 9 Speed Drivetrain Groupset - Black - Single Shift, Black
  • £195.00

Box Three Prime 9 Speed Drivetrain GroupsetThe Box Three groupset offers the same capability as its top-tier siblings but it's built around a simpler platform. The cassette is more accessible at 11-46T and fashioned without a spider. The rear mech exploits Box's Limited Slip clutch technology without the Tri-pack features. This allows you to shift easily with a comparable mechanism, although you'll forgo the hinged clamp and die-cast structure. Lastly, it's strung together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your mountain bike into the 21st century, then level up with this group.Box Three Prime 9 ShifterThe Box Three shifter makes good use of nylon composites in both top and bottom shells as well as the levers. Box Three is our performance and value tier. So this shifter sheds all the fancy trappings of the top 2 tiers but maintains their shifting characteristics. All Prime 9 shifters take advantage of the 9-speed's inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won't have to constantly adjust your set-up.Features: Material: Glass Fibre / Nylon Composite, Steel Extruded Clamp 2 Piece Pull Lever / Up to 3 Gears Per Shift Resin Top Shell Fast Action Release Lever Prime 9 Technology Multi Shift Option Not Intended for E-Bike Use Single Shift Option Recommended for E-Bike Use Weight: 128gBox Three Prime 9 Wide Rear DerailleurThe Box Three Rear Derailleur simplifies the features found on the Prime 9 Box One and Two rear derailleurs making for a fully-featured wallet-friendly rear derailleur.

  • Saving you £20

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.
