The crank is the very centre of SRAM’s X-Range gearing philosophy. With tight 13-tooth gaps between chainrings paired to wide-range cassettes, riders get more range while shifting less frequently and staying in the big ring longer. Their 43/30T chainring combo combined with a wide chainline increases tyre clearance while providing ideal gearing for venturing off-road.
Key Highlights Are X-Range gearing technology gives you more range Crisp and accurate front shifts Wide chainline crankset - bikes with 700x45c or 27.5x2.1” tyre widths (43/30T chainrings only) Longer DUB crank spindle accommodates both Road and MTB Requires Wide front derailleur DUB bottom bracket adds durability and simplicity Can be upgraded to a power metre
