Shimano's Dura-Ace 10-speed Cassette is comprised of an aluminum cog carrier, 4 titanium and 6 steel cogs (from largest to smallest respectively). This makes for a super-light and stiff cassette that makes your derailleur shift like a dream so you can dance up the climbs as easily and efficiently as your chain climbs up and down these cogs.

SRAM's PowerGlide PG-820 Cassette is a fine 8-speed cassette. It features steel cogs with SRAM's DuraBlast technology for smooth, precision shifting and excellent durability.

Shimano's 105 10-Speed Cassette delivers excellent shifting and durability. The cogs are made of long-lasing, smooth-running steel. They have Shimano's engineered tooth shapes for precision shifting. And for lightness, the cassette has an aluminum carrier for the top cogs and nylon spacers.

SRAM's PG-1030 10-Speed Cassette is a great choice. It's constructed of light and durable materials and boasts SRAM's PowerGlide tooth profiles and shift ramps for quick and positive gear changes every time. This trick cassette is available in four configurations perfect for riding off road, including one with a 36-tooth largest cog for super-easy climbing.

You've got to have the right ratio for the track, and Shimano's Dura-Ace cogs come in a range of tooth counts so you can always be prepared. Manufactured from durable chromoly steel, each cog is machined to run perfectly straight.

With its wide range, SRAM's XX1 11-Speed X-Glide Cassette gives you a clean, simple 1x11 drivetrain. It has a 10-42 tooth spread that gives you pretty much the same gearing as 2- and 3-ring setups without the REDundancy, shifting issues and weight penalty. Yes, you can still spin up your hardest climbs. A key thing to note, is that even with the huge range, there are no huge jumps or dips in the gearing, so your cadence and pedaling stay consistent as you move up and down the entire cassette. The wide open design makes it incREDibly lightweight and aids in mud clearance, giving you cleaner shifting and longer component life. It requires an XD driver hub freebody (sold separately) that further REDuces your wheel's weight and improves the hub connection. Welcome to the future of mountain bike drivetrains.

A range of sturdy, affordable cogs is an essential part of a single speeder's quiver. Origin-8's Torq Lite Single Speed Cog is available in wide range of sizes so you can easily tailor your gearing for the terrain. It's designed for Shimano/SRAM style cassette bodies, features a wide, flex-free base, and is made from hardened chromoly steel.

Pair this cog with your Shimano-compatible rear hub, spacers and a lockring (sold separately) and discover the joy and simplicity of a singlespeed without the cost of a new wheel. Machined from heat-treated chromoly and then chrome plated, these seriously tough cogs are strong, shiny and they come in sizes from 13T to 22T so you can pick the perfect gear.

SRAM's PG-1130 11-Speed Cassette is constructed of heat-treated steel cogs and boasts SRAM's PowerGlide tooth profiles and shift ramps for quick, positive gear changes. This excellent cassette also sports an aluminum spider construction for a maximum stiffness-to-weight ratio, a durable steel lockring, and comes in three wide ranges to suit your riding style.

For flawless shifting and maximum power transfer, Campagnolo brings you the Super Record 11-Speed Cassette. Its largest 6 cogs are constructed from titanium to save weight, while the other 5 are made of nickel-plated steel for durability. The cogs are mounted on a light and rigid aluminum carrier, and the cassette is secured to the rear wheel with a feathery aluminum lockring.

New Super Record 12 Speed sprocket cassettes: innovation which gives the user great advantages, thanks to the matching dimensions and complete compatibility with wheels and frames. The rider has always been Campagnolo’s focus, and the goal has always been facilitating their performance; making the impossible possible. Adding an additional sprocket might seem simple, however, we have not only succeeded in maintaining the same footprint, but also improving the component’s performance and durability, which was a tricky challenge! The new Super Record 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets, meeting everyone’s needs with just two (11:29; 11:32) cassettes. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist to find the perfect ratio for any situation. In addition, the closer sprockets ensure faster, quieter and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer lifespan. The 6 larger sprockets are also available in two single-piece steel triplets, to avoid energy loss. Mounting the cassettes is easy thanks to matching-thickness spacers.

Reliable, perfect shifting awaits with Shimano's Deore XT Dyna-Sys Cassette. It features chrome-plated steel sprockets mounted to two aluminum carriers for an ideal blend of durability and low weight. Closer gear ratios in the middle of the cassette ensure you'll have the perfect gear for the trail's ups and downs. Plus, the cogs are ramped and machined for flawless, lightning-fast shifts.
