This MTB cassette features Hyperglide sprockets, which use a computer designed tooth configuration with contoured shift gates. This results in a crisp and smooth shift even under load. Its sprockets are also cut away and drilled to reduce weight without reducing rigidity. One final highlight is its close ratio gearing allows a more efficient use of energy through finer cadence control.

The Hyperglide (HG) sprockets on the Shimano SLX 11 speed cassette have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Close ratio gearing allows more efficient use of energy through finer cadence control. Also, the sprockets are cut away and drilled to reduce weight without reducing rigidity.
Specially designed for use with Super Narrow 9-speed HG chains, the nickel-plated Shimano HG400 cassette is equipped with a range of gear ratios that make propelling the biggest of wheels over a variety of terrains and inclines a breeze. Contoured shift gates make for smooth shifting, while the sprockets themselves have been drilled down to minimise weight without compromising sturdiness and stiffness. Held firm by a corrosion-resistant, steel lockring, the Shimano HG400 9 speed cassette is the ideal cassette for long rides and exploring new terrains. Cassette Ratios: 11-12-13-14-16-18-21-24-28T 11-12-14-16-18-21-24-28-32T 11-13-15-17-20-23-26-30-34T
Available in two cassette ratios, the 11-25T is ideal for racing whilst the 12-2T8 is more suited to hill climbing sessions, such as sportives or endurance events.
The Hyperglide (HG) sprockets on the Shimano HG500 cassette have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Plus, the sprockets are cut away and drilled to reduce weight without reducing rigidity and the nickel-plated finish offers hard wearing resistance to corrosion.
A tough genuine Shimano tool. The LR10 lockring remover for centre lock disc rotors and HG cassettes makes the removal of these items easy. The large internal diameter allow the tool to slide over all axle locknuts. This tool can be operated using a 3/4 drive torque wrench or ratchet driver.
This freewheel features a rock-solid steel construction, which makes it perfect at handling all the knocks and bumps that are associated with long distance journeys. Whether you're using it on a mountain bike or road bike, this model's HyperGlide sprockets allow you to benefit from smooth and improved chain control during shifting. Technologies: HyperGlide Sprockets: The distinctively designed HYPERGLIDE sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. The HG freewheel sprocket, which was developed for the MTB 7 speed system, underwent comprehensive optimization to achieve super-highly efficient shifting. HG sprockets: Guide the chain quickly and directly to the next sprocket without override. Conventional sprockets: Cause the chain to ride up and over the gear teeth before engaging the sprocket.
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.
Thanks to its rigid alloy sprocket carrier, this 10-speed Shimano Ultegra 6700 road cassette offers the perfect balance of reduced weight and better shifting performance, even under the most demanding gear changes. This cassette will be compatible with any 10 Speed Shimano HG11 freehub, as well as any Shimano 10 speed chain. Please note: This item does not come with a freehub spacer.
Ready for racing, the superb Shimano R8000 cassette is equipped with 11 steel sprockets which are more than capable of handling all the intensity that comes with all-day road bike events. Using HG-EV technology, this version gives you a rider-tuned gear combination and cadence management. This means you'll benefit from its optimal gear ratio within your Ultegra groupset, which perfectly suits your riding discipline, so you can blast up to speed in seconds and maintain the edge over your competitors. Tech Tip: This cassette is compatible with all Shimano 11-speed road derailleurs. However, you should choose the same tooth count as your existing cassette or confirm the maximum cassette capacity for your derailleur before choosing) Please Note: The 11-34T version of this cassette is the "CS-HG800" model as Shimano does not make the CS-R8000 in an 11-34T version.
