Quarq DFour DUB Power Meter Spider 110 BCD 10/11 Speed
- Supplier Warehouse In StockUsually dispatched within 5-7 business days
A Quarq DFour power meter spider that measures both legs and runs Shimano road chainrings.
The DFour measures both legs to within ±1.5%. MagicZero calibrates it automatically during the ride, 10K TempComp compensates for temperature changes, and OmniCal lets you swap chainrings without affecting accuracy. It connects over BLE and ANT+, runs 200 hours on a CR2032 battery and carries an IPX7 waterproof rating.
It comes without chainrings: its 110 BCD is compatible with Dura-Ace R9100 rings, and it works with Ultegra R8000 and 105 R7000, though they won't match aesthetically. It must be used with a Quarq DZero DUB crankset and SRAM DUB bottom bracket, and firmware is handled in the SRAM AXS mobile app.
