Bicycle cassettes

Shimano's 105 group continues to lead the charge where performance to dollar value matters in its road group range and it fully benefits from the technology featured in its Ultegra and Dura-Ace components. The new R7000 group keeps this tradition alive and well and the 105 CS-R7000 Cassette is a shining example of a race-worthy cogset that the self-sponsoring racer can truly appreciate. Shift ramping and tooth profiles mirror that of its top-tier groups which provide nearly-identical shifting performance with only a slight increase in weight separating it from its pricier siblings. Weather and wear-resistant nickel plated steel cogs and an aluminum spider carrier helps boost the durability and …

With a focus on gear steps to help maintain performance and maximum cadence control, Shimano’s CS-M5100 Cassette for 11-speed drivetrains keeps you churning the correct cog no matter the terrain. The wide gear range may postpone your drop-in for the 12-speed group a bit longer, as the M5100 is undoubtedly designed to be a dependable workhorse and a worthy weekend racer. With terrain specific options, the 42-tooth or 51-tooth, you can ride long tempo climbs or have bail-out, switchback crusher. And the 11-speed design still allows a fast downhill 11-tooth cog to motor back to the trailhead.

Shimano's Ultegra CS-R8000 Cassette is among our top picks for high-level road cycling because like all Ultegra drivetrain components, it's the perennial favorite based on the performance-to-dollars equation. With different demands for drivetrain ranges required for road, gravel, and CX riding, Shimano has created cassette ranges designed to allow the R8000 drivetrain to easily satisfy the needs for a variety of riders. The Ultegra CS-R8000 Cassette ranges as high as 32t, so you can set up the new Ultegra (or Dura-Ace R9100) with the range you need for gravel epics, 4 corner crits, hill climbs, junior nationals, and everything in-between.

We're not afraid to assert that Shimano is the de facto leader in trickle-down technology. The brand consistently executes progressive changes across its componentry in a methodical, rather than frantic, fashion, then spreads those changes across the rest of its line like a fairy godmother in a familiar story. The brand bestowed this same magic on its redesigned SLX line, turning the workhorse line into a shiny group of moving parts that look and perform far beyond what their price suggests. The SLX CS-M7000 Cassette may not be the star of the show, but it didn't miss out on any of the magic dust. Crafting the cassette with an aluminum spider, Shimano shaved grams from the design compared to …

We hate to sound like cynics, but staring down at your cassette and praying for just one more miracle gear in the midst of a nausea-inducing climb will likely always be a part of cycling. The wider cassettes get, the more gears we'll wish for, which is why a workhorse cassette like SRAM's NX PG-1130 11-Speed Cassette is still a valuable choice. With its corrosion-resistant JET black finish, solid one-piece steel construction, and extensive 11-42t gear range, the PG-1130 was designed to accompany you through punishing climbs so you can blast through the descents on the other side. You'll just have to use those legs. And whether you're running SRAM one-by or still sticking to double, the cassette …

Ultegra might be the heart and soul of Shimano's line, and while we appreciate the precision, weight, and performance that goes into Dura Ace, we find Ultegra to be the perfect sweet-spot in the price-to-performance ratio. Shimano has created gear ranges in the Ultegra line for the most elite road cyclists to gravel grinders, and everything in between, so riders can achieve the sweet Ultegra feel no matter what they ride. In this particular iteration, Shimano creates the Ultegra CS-HG800 Cassette to fit on a mountain bike hub, so those running big touring setups or cross-bikes can now run the smooth shifting feel of Ultegra, and with the huge 11-34 tooth range you won't have issues finding the …

The SRAM PG-1170 Cassette provides smooth shifting across 11 gears with its semi-spidered steel cogs. Ideally pairing with SRAM's Force 22 groupset, the PG-1170 cassette features a 16T cog for extra cadence control and delightfully smooth shifting when you're hovering around the middle block of the cassette. X-Glide shifting technology eliminates flex between the teeth to enhance shifting smoothness, especially on downshifts. Note that SRAM recommends pairing this cassette with its PC-1170 chain for flawless shifting. Moreover, it's only compatible with 11-speed hub/freehub bodies, and it includes an anodized, laser-etched aluminum lockring.

The PG-1230 NX Eagle 12-Speed Cassette gives you nearly the same range as SRAM's other Eagle cassettes, but it works with normal splined freehub bodies, so there's no need for an XD driver. In order to accommodate this compatibility, there's one less tooth on the smallest cog, which is almost negligible for your top-end gearing. You still get the 50t bailout gear, as well as the PowerGlide II tooth profile and ramp design that work together to provide seamless transitions between gears, but it's made of all steel cogs to keep the cost reasonable and improve durability. The steel construction is so tough that the cassette is rated for E-MTB applications, so it will certainly withstand heavy-duty …
