Which bottom bracket should you choose with the Rotor Aldhu 12-speed crankset?
The Rotor Aldhu crankset is a premium aluminum model with CNC-machined crank arms, considered the flagship of Rotor's aluminum crank line. It is available in both 24 mm and 30 mm axle versions.
With a 24 mm axle, Aldhu can be mounted on a Shimano-compatible bottom bracket. However, upgrading to a ceramic bottom bracket improves overall performance and fluidity, without compromising on compatibility. We recommend the following high-quality models:
- BB86 frames (Canyon, Scott, Giant, Bianchi…): BB86 – CyclingCeramic
- BSA threaded frames (Tarmac SL7/SL8, Aethos, Supersix 2023…): BSA24 – CyclingCeramic
With a 30 mm axle, you must replace your bottom bracket. This version enhances performance and weight, and deserves top-tier ceramic or high-grade steel options depending on your budget. Here are our recommended models:
- BB86 frames (Canyon, Scott, Giant, Lapierre…): Bikone steel or CyclingCeramic ceramic
- BSA threaded frames (Specialized, Colnago, Cannondale…): Bikone steel or CyclingCeramic ceramic
- T47 internal frames (Trek, Look, Time…): CyclingCeramic T47 internal
- ITA frames (Pinarello): CyclingCeramic ITA30
- BB386 EVO frames: CyclingCeramic BB386 EVO
- BBright frames (Cervélo, no spacers needed): CyclingCeramic BBright

FAQ – Rotor ALDHU 12s Crankset
1. Why choose the Rotor ALDHU 12s over a Shimano 12-speed crankset?
- Modular design: configure crank arms, axle, spider, and chainrings independently.
- Direct mount interface: compatible with classic 2x spiders and 1-piece Spiderings.
- Wider gearing options: 50/34, 52/36, 53/39, and 54/42 — more than Shimano’s 52/36 max.
- Crank length range: 150–175 mm with the 30 mm axle; 155, 165, 170, 172.5, 175 mm with the 24 mm axle.
2. What chainrings are available for the ALDHU 12s?
Available with both round NOQ and oval Q RINGS: 50/34, 52/36, 53/39, 54/42. Oval chainrings remain popular among loyal Rotor users for their smoother pedaling feel — a legacy dating back to 2006.
3. What is the total weight of a complete ALDHU 12s crankset?
Typical total weight: 675 g (30 mm axle) or 750 g (24 mm axle). For detailed comparisons:
4. Can I use a power meter with the ALDHU 12s?
Yes, by replacing the spider with the INspider 2.0 power meter:
5. Is the ALDHU 12s future-proof?
Yes. Thanks to its modular and direct-mount design, the ALDHU 12s easily adapts to future drivetrain evolutions — Shimano, SRAM, or others.
6. Is the ALDHU 12s a long-term investment?
Definitely. You can reuse your crank arms across several drivetrain generations. For example, when Shimano moves from 8000 to 8100 series, ALDHU remains compatible — often requiring only a chainring change due to wear.
