The cassette is manufactured from a lightweight alloy and carbon fibre spider that houses 6 alloy sprockets and 5 titanium sprockets. The largest sprockets are manufactured from titanium to keep the weight low. The sprockets are also extensively cut away and drilled to further reduce weight without reducing rigidity. The very best and quickest shifts are optimised thanks to the Hyperglide EV sprockets that have a computer designed tooth configuration with contoured shift gates. All cassettes in the range will be compatible with the one rear derailleur so you can easily swap your cassettes out based on terrain.
Coming kitted out with a robust steel build, this Shimano Deore 9 speed chainring is engineered for toughness and dependability as you hit the trails. It's polished on the inner side and has a matt finish on the outside, while its pick-up teeth and ramps improve shifting speed. This is a genuine Shimano spare part. Sold individually.
The slick performing and durable Shimano Tiagra 4700 rear derailleur delivers high-performance gear changes and operation all at a low price. *Please note, due to a specific pull ratio, this derailleur is only compatible with Tiagra 4700 shifters.
The Hyperglide (HG) sprockets on the Shimano XT M8000 cassette enable the chain to move smoothly across the cassette even under load, resulting in a crisp shifting movement when required. These advanced sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Also, the close-ratio gearing enables more efficient use of energy through finer cadence control. That's not all, as the light and durable sprockets on the Shimano Deore XT M8000 mountain bike cassette are cut away and drilled to further reduce weight without reducing rigidity and their chrome-plated finish offers hard wearing resistance to corrosion.
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. Cassette Ratios: 11-13-15-17-19-21-23-26-30-34T 11-13-15-17-19-21-24-28-32-36T
The Shimano Deore XT M8000 rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design. Its Shadow cage has a slant angle that’s been optimised for use with larger sprockets and it features a super low profile design that reduces the risk of damage. The Shadow Plus system uses a chain stabilising switch that when on, reduces chain bounce in rough terrain maintaining a more stable drive and reliable shifting. This can be switched off to remove the wheel. The Direct Mount system on the Shimano Deore XT M8000 rear derailleur 11 Speed model gives you more space around the rear frame dropout. This results in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axle sizes and move suspension pivots.
With better and more comfortable brake hoods and a Style that follows the 105, Ultegra and Dura-Ace models, the Shimano Tiagra 4700 STI levers provide virtually effortless and accurate shifting operation. Ergonomic in design for a comfortable feel in the hands, they have a grey finish to match the rest of the Tiagra 4700 range.
The tactile buttons of these Shimano Di2 TT shifters allow effortless and comfortable shifting even when your hands are cold These switches give the added option of being able to operate the gears from either the aero extension or the ST-9071 Dual Control brake levers (sold separately).
Optimised for use with hard-riding 10-speed road bikes, this quality-built cassette is mainly aimed at racing juniors and lower teeth. Equipped with Hyperglide sprockets, computer designed for specific configurations, a smooth and reliable shift is assured, even under extreme pressures and conditions.
Tough, aggressive and light weight Dyna-Sys11 left hand SLX Rapidfire shift levers with Vivid indexing and 2-way release function. Light to the touch but positive and crisp, Vivid indexing provides a constant amount of shift lever force. 2-way release allows shifting from various riding positions; the upper lever still performs the same shift function, but it can now swing in either direction allowing it to be released by the thumb or index finger. Pod design allows the use of these shifters with any brake I-spec-II lever. Removable optical gear display with integrated cover allows the use of these shifters with any brake lever.
The easy to read gear display also shows the gear that you are using at any given time.
This Shimano Ultegra 10 speed bike chain is designed for optimum cassette and chainset interaction and maximum power transfer (recommended for use with double systems only). Its outer plate design has been developed to reduce the chance of chain suck and the inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near-silent running. Also compatible with Shimano 105 and Dura-Ace 10 Speed Drivetrains. Technologies: - The chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette. - Outer plate design has been developed to reduce the chance of chain suck. - The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent-running. - Optimised for 10-speed Super Narrow HG drivetrains.
