This trail-ready mountain bike (MTB) cassette features hard-wearing steel cogs, which allows it to handle all the demands associated with all-day epics on your favourite trails. SunRace has also equipped this model with an alloy lockring and spider for additional strength and durability, while its numerous holes keep its weight reduced to a minimum. Benefitting from an ED black coating, it offers fantastic wear resistance as you charge from trail to trail. Another highlight is its wide 11-51 tooth ratio that's paired with Fluid Drive Plus technology for consistent shifting performance, wherever your next adventure takes you. Please note: This is a Shimano HG fitment option and does not fit Shimano MicroSpline. Manufacturer's Part Number: 88215229 Black/Red 11-51T Shimano/SRAM
Allows the use of 9, 10 and 11 speed Campagnolo cassettes on Elite indoor trainers.
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. Cassette Ratios: 11-25T: 11-12-13-14-15-16-17-19-21-23-25T 11-28T: 11-12-13-14-15-17-19-21-23-25-28T 11-30T: 11-12-13-14-15-17-19-21-24-27-30T 11-32T: 11-12-13-14-16-18-20-22-25-28-32T 11-34T: 11-13-15-17-19-21-23-25-27-30-34T Technologies: HG-EV: HG-EV cassette sprocket is for rider-tuned gear combination & cadence management. Shimano provides an optimal 11-speed drivetrain gear ratio; you can choose wider and closer gear combinations to match various riding disciplines. HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved Hyperglide shifting. HG-X11: Silky driving, accurate shifting. HG-X11 directional chain realises smoother shifts and greater overall performance. The right and left sides are optimised for front and rear shifting respectively.
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 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.
The Dyna-Sys technology on the Shimano XT M771 cassette provides more efficient power transfer. The power of the rider is transferred more efficiently due to reduced chain tension, less need to change gear and improved continuous cadence due to a closer chainring combination on the chainset and wider cassette ratios. These points improve pedalling efficiency, give smoother and more comfortable front shifting while having less effect on pedal feedback when used on suspension bikes.

The close-ratio gearing of the Shimano HG50 8 speed cassette allows more efficient use of energy through finer cadence control. The sprockets are cut away to further reduce weight without reducing rigidity and the Nickel-plated finish offers hard wearing resistance to corrosion.
8-Speed SM-S500A for SG-S501 11-Speed SM-S700 for SG-S700
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.
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.
