SRAM Force AXS E1 DUB Power Meter Thread Mount Crankset - 172.5mm48/35T

Built for precision and control, the SRAM Force AXS E1 DUB Power Meter Thread Mount Crankset delivers dual-leg power measurement with +/-1.5% accuracy. Featuring integrated chainrings, X-Range gearing, and a carbon crank arm, it combines high-level performance with rider-focused serviceability. It uses the same proven tech as the RED AXS power meter and lets you easily change chainrings to suit your ride.Key Features and Benefits:Integrated power meter with thread-mounted chainrings: Embeds the power meter into the chainring structure using a thread mount. This design lowers overall weight while improving stiffness and simplifies installation or replacement of different chainring sizes.Dual-leg power measurement with +/-1.5% accuracy: Measures both right and left leg output independently and maintains consistent accuracy regardless of temperature changes. This ensures reliable, high-resolution performance data every ride.X-Range gearing technology: Optimises gear steps with tight jumps and a wide range by pairing smaller front chainrings with a wider-range cassette. This delivers smoother transitions and keeps you in the right cadence without large shifts.DUB bottom bracket system: Uses a single spindle size for all frame standards and larger bearings for improved durability. This simplifies setup, reduces maintenance needs, and increases long-term drivetrain efficiency.Carbon crank arms: Made from lightweight carbon to reduce rotational weight without sacrificing strength. This helps improve pedalling efficiency and responsiveness under load.Thread Mount BCD system: Uses a direct thread-mounting interface for chainrings instead of traditional bolts. This allows faster chainring swaps and improves power transfer by reducing flex at the mounting point.When choosing a power meter, most riders want reliable data, low maintenance, and smooth compatibility across components. The Force AXS E1 crankset meets these needs with a fully integrated design, serviceable thread-mounted chainrings, and precise dual-leg measurement. Its X-Range gearing works seamlessly with modern cassettes, helping maintain optimal cadence on variable terrain, while the DUB interface ensures lasting reliability.Take control of your performance data with proven technology and simple service features that fit into your ride without compromise.Specification: Speeds 12BB Compatibility All SRAM Road DUB BBsChainring Size 46/33T, 48/35T, 50/37TCrank arm length 160mm, 165mm, 170mm, 172.5mm, 175mmChainline 45.0mmBB Spindle Interface DUBChainring material AluminiumGuard No GuardBolt Circle Diameter (BCD) Thread MountCrank arm material CarbonPower meter YesPower Meter Type Spider
