SRAM NX Eagle Crankset The SRAM NX crankset delivers Eagle styling and performance to the newest addition to the Eagle ecosystem. Designed for SRAM's X-SYNC 2 chainrings, the NX crankset is engineered for complete chain control-each tooth's profile is precisely engineered to work quietly, efficiently and securely with the Eagle chain's inner and outer links. DUB technology features a better-engineered bottom bracket and a new spindle design, which together allows for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of performance and durability Features 6000 series forged aluminum arms DUB technology features a uniform approach to bottom bracket fitment Better sealing against contamination and is forward and backward compatible Eagle styling and performance The NX crankset brings the sleek aesthetics and high-performance capabilities of SRAM's Eagle drivetrain to a wider audience Engineered for use with SRAM's X-SYNC 2 chainrings, the NX crankset ensures precise chain control. Each tooth profile is meticulously designed to work seamlessly with the Eagle chain's inner and outer links, resulting in quiet, efficient, and secure operation. The NX crankset features SRAM's innovative DUB technology, which includes a better-engineered bottom bracket and a new spindle design. This approach ensures a more uniform fitment of the bottom bracket, better sealing against contamination, and compatibility with both forward and backward configurationsWith its Eagle styling, complete chain control, and DUB technology, the NX crankset delivers a new level of performance and durabilityRiders can expect reliable operation and long-lasting performance, even in demanding riding conditions SRAM NX Eagle Crankset SRAM GX Eagle Boost Crankset SRAM GX Eagle Crankset SRAM GX Eagle Carbon Boost Crankset Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.6 out of 5 stars 164 5.0 out of 5 stars 1 4.6 out of 5 stars 121 4.0 out of 5 stars 17 Price $113.00$113.00 $137.57$137.57 $142.32$142.32 $264.17$264.17 Speeds 11/12 11/12 11/12 11/12 BB Compatibility DUB BSA MTB 100, DUB PF MTB 121, DUB BSA73,DUB PF89.5,DUB PF92,DUB PF30 MTB73,DUB BB30 MTB73, DUB:BSA73, PF89.5, PF92, PF30 MTB73, BB30 MTB73, BSA MTB68SP DUB BSA MTB 100, DUB PF MTB 121, DUB BSA73 SB+, DUB PF92 SB+, DUB:BSA73, PF89.5, PF92, PF30 MTB73, BB30 MTB73, BSA MTB68SP DUB:BSA73, PF89.5, PF92, PF30 MTB73, BB30 MTB73, BSA MTB68SP DUB:BSA73, PF89.5, PF92, PF30 MTB73, BB30 MTB73, BSA MTB68SP Chainring Size 30T, 32T, 34T 30T, 32T, 34T 30T, 32T 32T Crank arm length 165mm, 170mm, 175mm 165mm, 170mm, 175mm 165mm, 170mm, 175mm 170mm, 175mm Chainline 49.0mm, 52.0mm, 66.5mm, 76.5mm 49.0mm, 52.0mm, 55.0mm, 56.5mm, 66.5mm, 76.5mm 49.0mm, 52.0mm, 55.0mm, 56.5mm, 66.5mm, 76.5mm 52.0mm BB Spindle Interface DUB DUB DUB DUB Bolt Circle Diameter (BCD) Direct Mount (DM) Direct Mount (DM) Direct Mount (DM) Direct Mount (DM) X-SYNC 2 A proprietary tooth profile technology used in chainrings, particularly in mountain bike drivetrains. It's designed to improve chain retention, reduce chain noise, and enhance overall performance, especially in demanding off-road conditions. X-SYNC 2 chainrings have a unique tooth profile The design alternates between narrow and wide teeth Boost A specific spacing standard for bike components, particularly for mountain bikes. It involves widening the spacing between the front and/or rear hub flanges, allowing for stronger and stiffer wheel builds. Boost spacing allows for greater clearance between the tires and the frame or fork, accommodating wider tires without compromising frame geometry By widening the rear hub spacing, Boost helps optimize the frame geometry, providing better handling and stability, especially on rough terrain The wider hub flange spacing results in shorter spokes and increased bracing angles Leading to stiffer and more responsive wheels that transfer power more efficiently Boost spacing supports larger wheel and tire sizes, enabling riders to use 27.5+ and 29-inch wheels with wider tires for enhanced traction and control
