Velo-Perso's Review:

• High manufacturing quality thanks to CNC machined crank arms, embodying Rotor's DNA.
• Competitive weight with 30mm axle, heavier by 70g in the 24mm version.
• Allows multiple positions for Qrings.
• Wide range of chainring options (50/34, 52/36, 53/39, 54/42) provides more flexibility compared to competitors like Shimano, which typically limits to 52/36 except for Dura-Ace.

Component Weights:

• Crank Arms: 350-360g
• Spindle: 99g (30mm), 140g (24mm)
• Spider: 51g
• Bolts: 8g
• Chainrings: 31g (34) to 49g (39), 119g (50), 139g (53)

FAQ:

1. Why choose the Rotor ALDHU 12s over a Shimano 12-speed crankset?

The Rotor ALDHU 12s offers several advantages over Shimano's 12-speed cranksets:

• Modular crankset design: With Rotor, you can easily customize your setup by mixing and matching components to meet your specific needs. Shimano cranksets do not offer this level of modularity.
• Wider range of chainring options: The ALDHU 12s has a broader selection of chainring combinations compared to Shimano, allowing for finer tuning of your gearing to suit different riding styles and terrains.
• Crank length variety: Rotor provides more options when it comes to crank arm lengths, giving you more flexibility to find the perfect fit for your riding position.

2. What are the benefits of the 24mm version of the ALDHU 12s?

The 24mm version of the ALDHU 12s crankset offers:

• High-quality manufacturing: Rotor is known for precision engineering, and the 24mm crankset maintains their high standards of craftsmanship.
• Modular crankset design: This version allows you to easily switch out crank arms and chainrings for full customization.
• Wider availability of chainrings: You'll find a much broader selection of tooth sizes for both inner and outer chainrings compared to other cranksets on the market.
• Crank arm length options: The 24mm version offers a greater variety of crank lengths, helping riders achieve an optimal fit.

3. What are the advantages of the 30mm version of the ALDHU 12s crankset?

The 30mm version shares all the benefits of the 24mm model, but with some additional features:

• Weight savings: The 30mm crankset is 70g lighter than the 24mm version, which is a significant reduction for those seeking performance gains through lighter components.
• Even more crank length options: The 30mm version provides an even larger selection of crank lengths to ensure precise rider fit.
• 30mm bottom bracket requirement: One consideration is that you’ll need to use a 30mm bottom bracket for this version, but the weight savings and increased crank arm variety make it worthwhile.

4. Can I switch between the 24mm and 30mm versions?

No, since the 24mm and 30mm cranksets require different bottom brackets, you would need to change the bottom bracket to switch between these two versions. However, the modular nature of the ALDHU system makes it easy to upgrade or change parts without replacing the entire crankset. The 24 & 30mm versions are sharing the same parts: spiders, chainrings. Axle & arms are specific to each 24/30mm.

5. What kind of chainrings are compatible with the ALDHU 12s?

The ALDHU 12s is compatible with a wide range of chainrings, including both round and oval chainrings (Q Rings). This allows you to further tailor your bike's performance to your riding style and preferences.

6. Is the Rotor ALDHU 12s compatible with other drivetrain systems?

Yes, the Rotor ALDHU 12s crankset is designed to be compatible with most major drivetrain systems, including Shimano and SRAM. However, it’s always important to double-check specific compatibility with your bike's setup. We have specific Sram AXS chairnings compatible with Aldhu (48/35 & 50/37 only).
