This high-quality 12 speed cassette is ideal for gravel riding as it comes fully equipped with some of the finest technologies available from SRAM for maximum performance on your travels. Ready for exploring countryside backroads with mixed terrain conditions, this model is kitted out with a wide 440% range, which makes gravel mountain climbs less daunting while its tight jumps between its higher cogs allow you to get the power down when accelerating on the asphalt. Specifically designed for use with SRAM XPLR 1x rear derailleurs, each cog has shift features that are optimised for electronic shifting. This means that riders will enjoy electronic benefits such as faster, smoother & more accurate shifts, so you're always in the right gear. X-Range Optimised 12 Speed Cassette Due to today's drop bar bikes being faster & more capable than ever before, riders want a shifting set-up with wide-range gearing to match their wide range of cycling pursuits. But, as the range is only half of the equation, they also want a drivetrain that offers the right gear for any situation. By starting X-Range cassettes with a 10T cog, SRAM is able to keep the cogs & chainrings smaller overall, eliminating the potential weight gain of a wide-range 11-tooth start drivetrain. It's the best way to expand the range & keep small jumps between cogs. X-Range achieves wider range & tighter jumps by going to a 12-speed cassette, but also by moving some of the gear range from the front of the drivetrain to the back. That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. & when a front shift is executed, the smaller jump is smoother & means that you can get to the right cadence with fewer compensation shifts in the rear. Fewer, faster front shifts make it easier for you to find the right gear, & that’s a distinct performance advantage relative to traditional drivetrains. 440% Range for Gravel Riding Make that daily ride from your front door a little spicier with some dirt. The 440% range of the XPLR XG-1271 cassette provides smooth gear progression when you’re sweating up gravel climbs, & tight jumps on the high end for when it’s time to drill it on asphalt. Shift features on each cog are optimised for electronic shifting, so you’ll get fast, smooth & precise shifts every time.
