Boulder, Colorado-based company Stages Cycling is launching a new direct-
measurement power meter at Interbike that weighs just 20g and costs as
little as $699.
The StageONE power meter is built into slightly modified left-hand crankarms
and directly measures power via a strain gage array, custom electronics,
and a special algorithm that filters out non-applicable forces and
interpolates total left-plus-right output. Claimed accuracy is within +/-2
percent.
The complete model and pricing run-down is as follows, based on crank
