QUARQ SRAM RED DZERO POWER METER
The DZero is the latest in the line of Quarq’s 10 years of power meter design. This £858 model features in-built cadence measurement, so no more magnets, increased accuracy to within 1.5 per cent of both legs, improved battery life – up to 200 hours from a replaceable CR2032 cell – and improved temperature compensation. We’ll be testing it to see if Quarq’s claims do improve what we already rate as one of the best meters around.
