The new QO Race SL crankset showcases how high-grade carbon fiber and smart design can push cycling components to new limits. Recently unveiled at Eurobike 2025, this crankset is engineered for road cyclists who want the lightest possible setup without sacrificing stiffness or drivetrain compatibility.
At the core of the Race SL is its construction from Mitsubishi Pyrofil carbon, a premium-grade material known for its excellent stiffness-to-weight ratio and fatigue resistance. The crank arms also feature a unique micro-dimpled surface, inspired by aerospace and wheel design, to reduce drag by creating a turbulent boundary layer — a technique popularized in high-performance wheels like Zipp.
Weighing just 510 grams with 50/34T chainrings, the Race SL puts itself among the lightest cranksets on the market, yet remains accessible at a price point under 900 euros. The 28.99 mm aluminum spindle aligns with SRAM’s DUB standard, enhancing stiffness while ensuring broad bottom bracket compatibility.
Function meets form with a minimalist design and modular chainring system. Riders can choose between 50/34, 52/36, and 54/40 options, all compatible with both Shimano and SRAM Flattop drivetrains. Available in 160 to 175 mm crankarm lengths, the Race SL offers real-world versatility backed by carbon engineering excellence.
For fans of advanced composites and cycling tech, the QO Race SL is a clear example of how applied carbon fiber technology continues to evolve in the performance cycling world.
