XX1 Chapter 3–Cross Country

SRAM's Single-Ring Drivetrain on the XC side of racing

By Vernon Felton

In Chapter Three of SRAM’s video series on XX1, the company explains how its new single-ring drivetrain system can excel at both hard-charging all-mountain/enduro riding and cross-country racing, which for the record, is a seriously tall order.

Even if you have zero interest in World Cup-level XC racing, this is a good clip to check out as the video details some of the key technologies that underpin XX1; the bit about the cassette and driver body is especially impressive and goes a long way towards illustrating what I and a bunch of other hacks have been trying to explain with nouns and verbs.
