We shift smoothly across everything from steep, rock-strewn trails to smooth-buffed XC loops with the Shimano XT CS-M8000 Cassette. Whether we're overhauling our trail bike's chewed-up cassette or converting to a 1x11 drivetrain, this 11-speed cassette shaves precious grams while standing up to...

Fancy drivetrains like XTR may get the first hit of sleek new technology, but fortunately for us, Shimano doesn't lag when it comes to trickling the tech through the lineup, which is easy to see with the new XT CS-M8100 12-Speed Cassette. The new 12-speed XT cassette comes with a complete...

The XT 10-Speed Cassette uses plated steel cogs for superior durability, but that doesn't mean that it weighs a ton. The largest six cogs are minimal in design and are pinned to two lightweight alloy spiders -- three cogs for each spider. The four smallest cogs go on separately, and the whole...

There's no need to deal with shifting that interrupts our pedal stroke when we can have the XTR CS-M9101 12-Speed Cassette, which delivers definitive shifting that lets us pedal continuously. This cassette lets us shift smoothly and quietly, and it offers increased acceleration by reducing...

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...

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...

The SRAM PG-720 7-Speed Cassette features a compact design for ripping blistering downhill laps, but without the sticker shock you're accustomed to. As the most affordable 1x downhill cassette on the market, this 11-25 tooth cassette emphasizes robust strength and smooth-shifting over the...
