TriRig's Alpha series revolutionised triathlon cockpit design, setting the standard for aerodynamics, adjustability, and simplicity. The Alpha Prime's patented design makes it the world’s first universal aerobar with continuous, vertical, single-bolt stack adjustment.
Dialling in your fit is as easy as loosening a single bolt, allowing tilt adjustments on the fly. With highly adjustable pad stance positions and five accessory mount bosses for BTA bottles, computer, or storage, Alpha Prime is our fastest bar ever—and fully UCI legal.
Alpha Prime is engineered for adaptability, enabling precise fit adjustments without the need for additional components or time-consuming mechanic appointments. Whether you're fine-tuning your position by dropping 5mm for enhanced aerodynamics or raising the bars to prioritise comfort, Alpha Prime provides the flexibility to evolve your setup with just a single hex wrench.
Get ready to transform your ride with Alpha Prime—it’s not just an upgrade, it’s a whole new experience.
