The crankset is the heart of your drivetrain, and in 2025, elite riders are demanding more than ever: ultralight materials, modular setups, power meter integration, and aerodynamic designs. At CARBONRAW, we’ve reviewed some of the best carbon road bike cranksets this year for performance-focused cyclists who won’t compromise.
1. ROTOR Aldhu Carbon: Precision and Modularity
ROTOR continues to set the benchmark with the Aldhu Carbon crankset. Known for its modularity, it supports Q Rings, direct mount setups, and internal INpower power meters. With CNC-machined carbon arms and a lightweight structure, it balances stiffness and versatility for racers who like to fine-tune their drivetrain.
Key strengths: Oval chainring compatibility, power meter integration, top-tier stiffness.
2. QO-RACE: European Carbon Innovation at a Competitive Edge
QO enters the top tier in 2025 with its QO-RACE crankset—a fully carbon system developed for high-performance road cycling. Designed and manufactured in Europe, it features direct mount chainring compatibility, optimized geometry, and exceptional weight-to-stiffness ratio.
Key strengths: Aggressive design, competitive weight, made in Europe, rising alternative to legacy brands.
3. THM Clavicula SE: The Lightweight Reference
THM continues to push boundaries with the Clavicula SE—one of the lightest carbon cranksets available. Handcrafted in Germany, it’s a premium option for riders who count grams and demand maximum responsiveness, especially in climbing stages or TT setups.
Key strengths: Class-leading weight, elegant minimalism, extremely high-end finish.
4. SRAM RED AXS: Integrated Performance and Power
While technically heavier than boutique options, SRAM RED AXS offers seamless wireless shifting and integrated Quarq power meters, making it a preferred choice for pros focused on data and drivetrain integration. Its carbon crankarms and aero design make it ideal for triathlon and road racing.
Key strengths: Wireless integration, reliable power data, full-system efficiency.
5. Campagnolo Super Record: Classic Meets Carbon
Campagnolo’s Super Record crankset combines traditional Italian elegance with modern carbon construction. Featuring an iconic four-arm spider and hollow carbon arms, it remains a favorite among purists who also value cutting-edge performance.
Key strengths: Timeless design, smooth shifting, proven reliability.
How to Choose the Right Crankset in 2025
Choosing your ideal road bike crankset depends on:
- Power goals (e.g. integrated meter vs. lightweight priority)
- Terrain (climbing, TT, or flat speed)
- Modularity (ring compatibility, BB types, spindle swaps)
- Aesthetic preference and drivetrain compatibility
