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
This tough model is constructed from aluminium which makes it ideal for withstanding the abuse which comes with trail riding. Stable and versatile, you'll benefit from its superior modulation which gives you excellent control on the rowdier terrain sections. Furthermore, its quicker piston retraction delivers more accurate operation, so you can ride more efficiently and confidently. Technologies: Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system. Click here to view the Shimano Brake Reference Guide.
The Shimano EW-WU111 is a Di2 component that allows wire-free communication between your shifters and a compatible smartphone or tablet. This means you no longer need to physically connect your bike to the PCE1 interface to carry out tasks such as updating the system firmware or to customise things such as shifting speed and shifts per click.
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.
Specifically designed for use with E-bike drivetrains, this right crank arm features a hard-wearing hollow aluminium construction. This makes it perfect at handling all the abuse that comes with all-day epics in the mountains. Shimano has also equipped this model with an anodised finish, which gives it additional protection against corrosion and the elements. Another benefit of its hollow-forged construction is it overs a superior strength to weight ratio, so you can benefit from its exceptional durability without adding any unnecessary grams to your E-bike. Technologies: Hollowtech: Hollow forged crank arms. A lightweight crankset not only reduces the bike’s weight, but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. SHIMANO’s advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight.
