The Rotor Aldhu Carbon 12V Crankset epitomizes performance and versatility. Designed for demanding cyclists, this crankset is not only lightweight but also extremely rigid, ensuring optimal power transfer.

In this spider mount version, you have the option to choose the exact chainrings you need. Rotor chainrings are specifically optimized for Shimano and Sram 12-speed chains, offering a variety of chainring options to meet all your needs.

Review from velo-perso.com: "It's hard to find something more versatile in performance: the chainrings are lightweight and nearly as light as the spidering version. The chainrings are optimized for 12-speed chains, and we also offer the AXS version."

The glossy spider of the crankset complements the elegant look of the carbon crank arms. The chainrings are machined to minimize weight without compromising rigidity, competing with Shimano's high-end offerings.
