Quarq DFour AXS DUB Power Meter Spider - 110 BCD, Spider Only

Quarq DFour AXS DUB Power Meter Spider combines the advanced power meter technology with SRAM s innovative DUB platform to bring you a simple spider-based power meter. We chose to offer the Quarq DZero power meter because to us, there is no better way to measure power on a Sram based system - or others for that matter - than with a crank based unit. The DZero is modern and lacks the finkey nature you see on so many add on brands or third party offerings away from the big three and SRM. Chose the DZero if you want repetable quality performance each and every ride in a crank based power meter. It features:

• Simplified part choices, quality materials and a broader compatibility for bottom brackets and chainrings, brings power on every ride
• DFour DUB is designed for Dura-Ace R9100 chainrings
• Spider must be paired with a compatible Quarq DZero DUB crankset and SRAM DUB bottom bracket
• Bluetooth low energy technology and ANT+ wireless data transfer
• MagicZero technology automatically checks and recalibrates your power meter as you ride no need to manually calibrate
• AxCad system provides no-magnet cadence data
• Use the AXS app to easily update firmware and view power meter metrics
• Measures power for both legs with +/- 1.5% accuracy
• Uses a CR2032 battery that can be replaced without tools
• OmniCal system allows you to swap chainrings without affecting accuracy
• IPX7 waterproof rating
