Lighter. Stiffer. Faster. The Ultimate Crank Arm Upgrade.

Experience a tangible performance boost with the Neutron Carbon Crank Arm. Meticulously engineered from full carbon fiber, this crankset is a testament to our obsession with stiffness, low weight, and rider-friendly design. It represents a significant leap forward, offering a 25% increase in stiffness and a 12% reduction in weight over our previous generation.
At a mere 335 grams (for a set of two arms and spindle), the Neutron Crank Arm is the perfect foundation for a featherlight build, providing the rigidity needed for explosive sprints and efficient climbing.


The Neutron Advantage: Designed for the Rider

We focused on the details that matter most to mechanics and discerning cyclists:
Effortless Installation: Built with a 24mm aluminum spindle and a SRAM 8-bolt mount, installation is straightforward. No proprietary tools or heavy-duty torque wrenches required.
Seamless Integration: A Q-factor identical to Shimano standards means no need for biomechanical adjustments. It’s a true plug-and-play upgrade.
Clean & Simple Setup: Forget fumbling with extra spacers. Our design ensures a faster, cleaner, and more precise installation right out of the box.


Build Your Perfect Drivetrain

The Neutron Crank Arm is the versatile heart of your custom setup. Choose your path:
Power-Ready: Select the SIGEYI AXO power meter spider for world-class, dual-sided power measurement with +/- 1.0% accuracy.
Power-Optional: Opt for the standard spider and upgrade to a power meter later.
Pure Lightweight: Choose the "Spider WITHOUT powermeter" option for the absolute lightest configuration.
