SRAM launches new NX mountain 1x drivetrain

SRAM introduces an even less expensive 1x drivetrain option for mountain bikers, the NX group.

Single-ring drivetrains keep getting more affordable, and SRAM’s new NX 1x mountain bike kit is the latest option for cash-strapped mountain bikers. It provides the wide gear range riders have enjoyed on the trails for years now, but at a more attainable price point. The X-Sync crankset, X-Horizon rear derailleur, X-Actuation shifters, and NX chain and cassette are fully compatible with all SRAM 1x drivetrains, but the cassette fits a normal freehub, not the SRAM-specific XD driver.
