Capture the spirit of classic racing with a modern twist using the Velo Orange Drillium Crankset. Inspired by vintage chainrings drilled to shave grams, the Drillium combines the iconic aesthetic of “drilled” rings with contemporary manufacturing precision, durability, and performance enhancements.

The crank arms and chainrings are cold-forged from 7075 aluminum alloy, offering strength and rigidity while minimizing flex. The thicker rings prevent bending under load, and the outer rings feature modern shifting aids such as ramps and pins, delivering smooth, precise front shifting. All hardware is stainless steel with Allen head nuts and bolts, and the included aluminum dust caps function as self-extracting crank hardware for easy maintenance.
