SRAM Force D1 Quarq 48T Aero DUB Carbon Crankset

The SRAM Force D1 Quarq 48T Aero DUB Carbon Crankset is designed for the rider who demands absolute aerodynamic efficiency and precise power measurement in a 1x system. This crankset combines the lightest carbon crank arms with a streamlined, one-piece 48T aero chainring. This unique Direct Mount chainring eliminates traditional spider bolts and is specifically shaped to minimize air resistance, which is crucial for time trials, triathlons, and fast, flat courses. The 48T chainring size, combined with a wide-range X-Range cassette, provides a broad and efficient gear range with smaller, more precise steps.

Power measurement is seamlessly integrated via the Quarq DUB-Pons Power Meter, which is directly incorporated into the DUB spindle. This design delivers reliable and consistent power data, with an accuracy of +/- 1.5%. Because the measurement is within the spindle and utilizes Active Temperature Compensation technology, the data is insensitive to temperature fluctuations and provides a consistent measurement of total power. Power supply via an easily replaceable lithium AAA battery (with over 400 hours of autonomy) ensures long and reliable operation.

The foundation of this system is the DUB (Durable Unified Bottom Bracket) spindle. This universal 28.99 mm platform ensures the best combination of stiffness – thanks to the oversized spindle – and durability through robust sealing. This makes the crankset compatible with virtually any modern bottom bracket standard, simplifying installation and maintenance. The Force D1 48T Aero PM is the proven choice for riders who want to combine impeccable aerodynamics with the simplicity and reliability of a 1x12-speed power meter system.
