SRAM have announced the details of their new NX drivetrain, which lowers the cost of upgrading to a 1x11 setup to previously unprecedented levels. The complete group – chain, cassette, cranks, shifter and derailleur – retails for $310 USD. To put that into perspective, the cassette alone from SRAM's highest end XX1 group goes for $416.



One of the noteworthy features of the new group is the 11-42 tooth cassette. Rather than requiring that riders use an XD driver, the cassette will fit on a standard freehub body. It's not exactly light, weighing in at a claimed 538 grams, but the $79 retail price will likely make those extra grams easier to overlook. The rest of the group shares a similar look to SRAM's higher end drivetrains, but less expensive materials and construction techniques have been used in order to keep the price down.



The bottom line? Expect to see 1x11 drivetrains popping up on more bikes than ever, and for front derailleurs to become increasingly rare. Read on for the details of the new group as provided by SRAM.
