Cross compatible!\u003c\/h2\u003e\n\u003cp\u003eE*thirteen expanded drivetrain possibilities for every rider with the original 9-50T Helix Race Cassette with 533% gear range. The proprietary 9t sprocket and patented two-piece construction gave riders an unprecedented ability to build the drivetrain of their choice. E*thirteen developed on that winning formula and added a 52T sprocket for an eye-watering 578% total range. Love to grind climbs? Throw on a 28T chainring and go pull some stumps. Hungry for top speed? Push a big ring, comfortable in the knowledge that you’ve got the most gear range you can get from a single-ring, 12-speed setup.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWidest range in the galaxy at 578%\u003c\/li\u003e\n\u003cli\u003eCross compatibility with Shimano, SRAM, and TRP drivetrains and chains\u003c\/li\u003e\n\u003cli\u003e2-piece forged\/machined design provides ease of assembly\/service and reduces waste\u003c\/li\u003e\n\u003cli\u003eAluminum and Steel clusters can be replaced separately to reduce service cost\u003c\/li\u003e\n\u003cli\u003e43-52t aluminum cluster backward compatible with 9-50T Helix plus or race cassettes\u003c\/li\u003e\n\u003cli\u003eUnique 9T high gear allows use of smaller chainrings for clearance and weight savings\u003c\/li\u003e\n\u003cli\u003e5 bright anodized or PVD color options \u003c\/li\u003e\n\u003cli\u003eTested extensively for analog and e-bike use\u003c\/li\u003e\n\u003cli\u003eHope XD drivers are undersized at the clamp location and require a Cassette Shim Kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cbr\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFreehub Mount: XD™ and XDR™ Drivers Only\u003c\/li\u003e\n\u003cli\u003eMaterial: 2 aluminum cogs, 10 steel cogs.
