News: SRAM X01 Drivetrain Announced

When SRAM released its unique XX1 drivetrain last year, we all knew this day was coming: the new 1×11 drivetrain technology is trickling down to more affordable component groups. (For more information on XX1, check out Jeff’s short review.) While X0-level tech still isn’t affordable by some people’s standards, compared to the premium cost of the XX1 drivetrain, it’s a definite improvement! Also, if the past is any indication, watch for 1×11 technology to continue to trickle down to X9-level groups and below.

The driving concepts behind the 1×11 drivetrain are more simplicity and more chain security (not to mention lighter weight), all while not compromising gearing range too drastically. 1×11 provides chain security and simplicity by eliminating front shifts, adding a clutch-style rear derailleur (now common on many 2×10 drivetrains as well), and using a unique asymmetrical chain design.

As for the new X01 version of the 1×11 concept, check out these details from SRAM:
