Quarq DFour DUB Power Meter Crankset

Quarq DFour DUB Power Meter Crankset
The Quarq DFour DUB Power Meter is designed for users of a Shimano crankset that want to step-up their game and start training with power! Featuring a 110 BCD, 4-bolt configuration, the DFour accepts all Shimano road chainrings. However, it is ideally suited for DURA-ACE 9100 rings specifically (for cosmetic purposes). This power meter benefits from over 10 years of Quarq’s experience in power meter technology. Therefore, it is accurate, durable and consistent in all conditions. It also has features such as MagicZero (automatically offsets) and 10K Temperature compensation (stays accurate regardless of temperature changes).
The DZero platform is now combined with SRAM’s new DUB technology. This means easy part choices, quality materials and a broader selection for bottom brackets and chainrings. The power meter runs for 200 hours on a single CR2032 battery and comes with a full 2-year warranty.
Please note, you must pair the Quarq DFour DUB Power Meter with Quarq DZero DUB crank arms and a SRAM DUB bottom bracket. Options
You can purchase the power meter with or without crank arms. Available crank arm sizes are:

165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm

Compatibility Crank arms:
You must pair the Quarq DFour DUB Power Meter spider with Quarq DZero DUB crank arms and a SRAM DUB bottom bracket. Chainrings:
The power meter is designed for use with Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings will also work, however they will not match the shape or color of the power meter as nicely. In the Box
