The high performance Shimano Deore XT M771 10 speed cassette features a light weight alloy carrier to mount the 6 largest sprockets, with most sprockets cut away and drilled to reduce weight without reducing rigidity. The chrome-plated cassette and lockring finish looks good and provides hard wearing resistance to corrosion. Designed specifically for use with Shimano's Dyna-Sys 10 speed standard, the close ratio gearing increases efficiency by allowing the rider finer cadence control, whilst the computer designed Hyperglide sprockets run extremely quietly when paired with a HG-X chain and feature contoured shift gates for crisp, smooth shifting even under load.Weight: 323g

Dyna-Sys is Shimano's next-generation MTB 10-speed drivetrain system and the Shimano HG81 10-speed cassette benefits from this to bring you an ultra-efficient drivetrain. Its sprockets have a spider arm for the three low sprockets and all the sprockets benefit from HyperGlide (HG) technology.

Light to the touch but positive and crisp, the Shimano XT M8000 shifter has Vivid indexing, which provides a constant amount of shift lever. Plus, with the 2-Way release function, the upper lever still performs the same shift function, but it can now swing in either direction. This gear lever also has a Multi Release feature that allows multiple gear changes with one sweep, further adding to the speed of shift. There’s also a multi-bearing design on this Shimano Deore XT shifter - 11 speed uses two ball bearing units to provide a low-friction and reliable shifting action. Please Note: As this shifter is designed to be combined with a Shimano I-Spec II brake lever, it does not come with its own round handlebar clamp.
Smooth Drivetrain Performance This Shimano XT 11 speed chainring features Dynamic Chain Engagement technology, which uses a unique tooth profile that provides superior chain retention, drivetrain smoothness and less chain noise. This updated version of the XT chainring includes a narrow-wide tooth profile for even better chain engagement and makes it the perfect chainring to suit any rider, in any condition. Technologies: Dynamic Chain Engagement: This technology effectively holds the chain and prevents chain drop. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge. This all aids drivetrain performance on uneven terrain, keeps chain noise low, drag to a minimum and increases chain and chainring durability.
This double crankset features a forged alloy crank arm construction, which makes it perfect at withstanding all the abuse that's associated with all-day epics in the mountains.

Alternative cable routing options allow for both brake and shifter cables to run along either side of the handlebar for optimum rider comfort. SRAM Rival also incorporates the popular reach adjust feature, which SRAM invented, and allows riders to customise their brake and shift levers. Now every rider has a choice on positioning their DoubleTap® levers. Weight: 320g Technologies: DoubleTap® shifting - this makes changing gears easier and faster, eliminating the cumbersome and awkward engagement associated with two-lever systems. DoubleTap handles up and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars. With short, rapid taps the transport pawl moves the ratchet wheel and up through the shifting range. Downshifting comes via a longer sweep of the lever (in the same inward direction you upshift, but to an ergonomically maximised 15° angle) with the holding pawl and the transport pawl leapfrogging each other quickly and smoothly. Exact Actuation™: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way ZeroLoss™: Simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle ground where you're waiting for the shift to come. Gear changes are instant and precise
Box Four 8 Speed Rear DeraileurThis Box Four rear mech is the base of Prime 9 Technology, which offers an affordable clutch based 1 by 8 speed derailleur that is simple and light. This makes it an ideal candidate for every entry-level bike that traditionally has a 3 by drivetrain that is neither durable nor user friendly. This rear mech is suitable for road and off-road use and gives rider's fast and consistent operation on the most demanding of rides.FAQ:Are Box Prime 9 derailleurs compatible with Shimano "direct mount" hangers? No, Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs.Is the Box Four Prime 9 Derailleur compatible with other 8 speed components? No, traditional 8 speed systems use a Cable Pull that is not compatible with Prime 9.Are Box Prime 9 derailleurs compatible with drop bar (road) shifters? No, Box Prime 9 derailleurs are not currently compatible with drop bar shifters, but we do offer a clamp for our shifters to mount on some 31.8mm drop handle bars.How should I clean my Box Four Prime 9 derailleur? We suggest removing the derailleur from the bike and using a soft bristle brush or rag with soapy water or a mild de-greaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.Features: Material: Aluminium, Glass Fibre / Nylon Composite, Steel Limited Slip Clutch Bearing Pulleys Nylon Composite Knuckle Direct Channel Cable Stay Die-Cast Linkages Stamped Inner and Outer Cage Compatible with Standard Derailleur Hangers (Non Direct-Mount)Compatibility: Box Four 8 Speed Shifter Black Box Four 8 Speed 116 Link Chain Natural Box Four 8 Speed 11-42T Cassette Black Box Four 8 speed Wide/Narrow Chainring 104BCD 32T BlackWeight: 328gBuy Box Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
