SRAM has just announced one of the first mountain bike-specific power meters: the Quarq XX1. Since Quarq falls under the SRAM umbrella, it seems fitting that this MTB power meter will be offered for the proven XX1 drivetrain.
While the obvious customers for a MTB power meter are XC racers performing at the top echelons of the sport, SRAM also claims that it’s useful for “marathon racers. . .to pace themselves and monitor energy loss” and interestingly “enduro and downhill racers. . .to see how often they pedal and how hard, analyze power and cadence vs. gear selection and seated vs. standing pedaling, and monitor fatigue.”
The entire crankset weighs in at 626 or 689 grams, depending on the bottom bracket type, and will retail for $1,500.
