Choosing the right carbon crankset is about more than just weight. For serious cyclists, it’s a decision that affects power transfer, stiffness, durability, and drivetrain integration. Here’s a look at some of the top carbon crank brands on the market—and why QO is rising fast among them.
ROTOR: Proven Innovation and Modularity
ROTOR’s Aldhu Carbon series stands out with its modular structure, allowing riders to swap spiders, chainrings, and even integrate power meters like INpower. Their patented Q Rings offer oval chainring benefits, and CNC-machined carbon arms combine stiffness with sleek aerodynamics.
THM Carbones: Featherweight German Precision
THM’s Clavicula SE is legendary for its ultra-low weight and minimalist aesthetic. Handcrafted in Germany, THM cranksets push the limits of carbon engineering, offering elite-level stiffness without sacrificing ride feel or reliability.
SRAM: Integrated Systems for Modern Drivetrains
With RED and Force AXS, SRAM has mastered the art of drivetrain integration. Their carbon cranksets offer electronic shifting compatibility, power meter options via Quarq, and aerodynamic profiles perfect for road and triathlon setups.
QO: A Rising European Carbon Force
Built in Europe with a focus on performance and efficiency, QO cranksets offer many of the features seen in top-tier brands—modularity, direct mount compatibility, low-profile design—at a competitive weight and stiffness ratio. Designed with both road and gravel in mind, QO represents a new generation of high-end carbon craftsmanship.
Other High-End Contenders
