SRAM's most advanced aluminium road crankset is also SRAM's most stunning. Careful engineering has resulted in crank arms that optimise stiffness to weight ratio, with material only where it's needed. Integrated chainrings deliver flawless shifting in ranges that fit your needs, with the whole package coming in over 50 grams lighter than the previous generation.

Technology

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings enabled by AXS. With X-Range, you’re always in the right gear.

X-Range achieves wider range and 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. We’ve employed smaller chainrings with a consistent 13T difference, while giving the cassettes a 10T-start for wider range (Up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to 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, and that’s a distinct performance advantage relative to traditional drivetrains.

By starting X-Range cassettes with a 10T cog, SRAM's able to keep the cogs and chainrings smaller overall, eliminating the potential weight gain of a wide-range 11-tooth start drivetrain. It's the best way to expand range and keep small jumps between cogs.

More range, tighter jumps, and smoother shifts. What's not to love? With X-Range, getting everything you’ve always wanted in a drivetrain has never been simpler.
