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.
Durable and with a race-proven design, the SRAM PG-850 cassette delivers reliable 8 speed shifting performance. It has a chrome-plated finish to help to ensure you'll enjoy years of hassle-free performance.
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.
The Brand-X 10 speed 11-36t MTB cassette is the perfect replacement for your 10 speed cassette. The cassette uses a standard Shimano HG spline and is made from high tensile steel so it's super hard wearing. The tooth profile has been optimised to aid gear changes and reduce noise.
Hard-wearing and accurately machined to run straight and true, ensuring an even tension in the chain.
Simply fit this sprocket to your existing 10 speedd cassette, using the clear instructions provided, and say goodbye to your front shift setup. See the compatibility chart here Click here to enlarge Q: Can I use the 40t expander cog with a 36t cassette A: We don't recommend using the 40t expander cog with a 36t cassette. Shift performance will be compromised as the timing will not be correct. Q: Can I use the 42t expander cog on my 34t cassette? A: The 42t expander cog WILL NOT work with 34t max cassettes. A 6 tooth jump is the maximum for good shifts. Q: I have a short cage dérailleur on my bike. Will that work? A: We recommend a medium or long cage dérailleur Q: Why do you only have a 42t expander cog for SRAM cassettes A: The 40t is available only for Shimano as SRAM is not offering a 34t cassette. Q: Is it hard to setup the expander cog? A: It's really not too hard, but you are working at the extreme limits of your rear dérailleur. If you have specific questions about the setup and adjustment, we recommend heading to your local bike shop. Q: I have a really worn drivetrain. Will the expander cog work ok on my bike? A: Old drivetrain components could cause poor shifting performance. We recommend a new chain and a new or well-cared for cassette.
Delivering crisp and precise shifting, even under load, the Shimano Acera HG41 8-Speed cassette has a nickel-plated finish to resist corrosion to add longevity. It offers close ratio sprockets with Shimano's bespoke Hyperglide design.
The Brand-X 9 speed 11-32t MTB cassette is the perfect replacement for your 9 speed cassette. The cassette uses a standard Shimano HG spline and is made from high tensile steel so it's super hard wearing. The tooth profile has been optimised to aid gear changes and reduce noise.
The cassette sprocket ratio has the same gear range as most modern 9 and 10-Speed drivetrains, but generally as there are fewer sprockets on an 8-Speed cassette, many believe shifting is not as smooth. However, SRAM designed this cassette with optimised 'shift-gates' and 'shift ramps' so that shifting efficiency and accuracy is excellent and top-performing across the entire cassette.
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.
Dependable and durable, this HG chain-compatible Hyperglide cassette features computer-designed teeth with specially contoured shift gates, making for an efficient an snappy switch between gears, especially under load. Built from a corrosion resistant steel and finished with nickel-plating for further strengthening, the cassette consists of specially cut sprockets to minimise weight without negatively impacting the stiffness.
Suited for the tenacity of World Cup racing as well as more timid trails, the ultra-efficient and effective SRAM PG-730 cassette combines lightweight steel chainrings with precision engineering to create a reliable 7-speed system.
