The Shimano R9100 11-Speed Cassette is part of the brand new R9100 Dura Ace range. Replacing the 9000 as Shimano s flagship groupset, the R9100 offers improved weight, exciting new features and superior performance. The R9100 is a super lightweight HG-EV cassette with a ridged carbon and alloy carrier to provide excellent shifting even under the most demanding gear changes, Hyperglide EV sprockets with a computer designed tooth configuration and contoured shift gates to ensure crisp and smooth shifting even under load and a close ratio gearing to allow for a more efficient use of energy through finer cadence control. The sprockets are all extensively cut away and drilled to reduce weight, the largest of which are mounted on lightweight alloy and carbon carriers and constructed from titanium to further reduce weight and increase rigidity without sacrificing strength. The R9100 has an alloy cassette lockring and features a nickel-plated finish for hard wearing resistance to corrosion. If you re looking to replace or upgrade your HG-EV cassette, you won t be disappointed with the Dura Ace R9100.

The Shimano Deore CS-M4100 10-speed cassette offers a wide range of gearing options. With its lightweight sprocket carrier, it delivers smooth gear steps and precise shifting. 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 cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimisation to achieve super-highly efficient shifting.Deore M4100 10-Speed Dyna-Sys cassette featuring light weight minimal design sprocket carrierThe 3 largest sprockets are mounted on a lightweight steel carrier to reduce weight and increase rigidityHyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlSprockets are cut away and drilled to reduce weight without reducing rigidityFor 10-speed HG-X MTB chains
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
