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.

Machined from heat-treated, chrome-plated chromoly, these seriously tough cogs will hold up to massive track sprints and crazy skid-stops. Surly's Track Cogs are strong, shiny and they come in two widths and sizes from 13T to 22T so you can select the perfect gear.

Once again, SRAM pushes the envelope with their Powerdome X XG-1090 10-Speed Cassette. Light, stiff, quick, and quiet thanks to the ultra-strong, hollow, one-piece design and StealthRing elastomers, this cassette is worthy of even the nicest road machines. SRAM has added elastomer rings between every cog to provide a 'bed' where the plates of the chain interface with the cog. These elastomer StealthRings make for whisper-quiet operation. It's light, too, with the small 11T cog separate, and the remaining 9 cogs milled from a solid block of tool-grade steel pressed onto a single aluminium cog (the largest one). And, to REDuce even more weight, excess material in the space between each cog is milled away.

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.

Take a quick look at the X-DOME Eagle cassette. The last dangling shred of an argument in favor of a mountain bike front derailleur is now officially dead. Designed for use with SRAM's proven, reliable XD driver body, this 12-speed, 10- to 50-tooth cassette offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME architecture, which, independent tests have concluded, yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention.
