State of the art technology makes for highly accurate and reliable power readings from the Quarq DZero 11R-110 Hidden Bolt GXP Power Meter.

The aluminium spider and crank arms are light and incredibly strong and stiff, and the 10K temperature compensation and IPX7 waterproofing ensure functionality in the worst conditions. Power is measured from both legs, and there's no need for a separate cadence magnet.

Quarq DZero 11R-110 Hidden Bolt GXP Aluminium Power Meter

Quarq's DZero 11R-110 Hidden Bolt GXP Aluminium Power Meter is highly compatible and incorporates ten years of research into its design. Power is measured from both legs, and the reading are highly accurate - to within 1.5% of your true outputs. With 10K temperature compensation and IPX7 waterproofing, the weather won't affect your results or the reliability of the system.

Forged aluminium crank arms and a CNC machined alloy spider make this an incredibly strong unit that retains a low weight and is stiff enough to ensure all your watts are transferred. You can stay up to date with the latest firmware via the Qalvin app, and the battery lasts an incredible 200 hours so you won't have to think about replacement too often.

Compatible with 10 and 11-speed drivetrains. Not compatible with Campagnolo chainrings. Please note, this forged aluminium model does not work with BBright or BB386EVO bottom brackets. This is the hidden bolt edition and pairing with SRAM chainrings will align the chain derailment pin and crank arm.
