Alpha Prime Carbon Aero Bar/Stem Combo System

Alpha Prime Aero Bar: The Ultimate Aerodynamic Upgrade

TriRig's Alpha series revolutionized 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. 

Dialing 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 prioritize 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.

How does shipping work?

We offer a variety of shipping options for both US and international customers. Giving you the power to choose your transit time. You'll see multiple options on shipping times and prices that are calculated in real time based on your location.

How long does shipping take?

Transit times are dependent upon the shipping option you select. In general shipping within the US takes 3-5 days of transit time, but this will depend on your shipping selection.

International shipment transit times will vary. This again is dependent on the shipping option you've selected.

On every order you'll receive tracking as soon as your order ships. We encourage you to follow along with shipping updates with the carrier you've selected.

International shipping. What to expect.

We ship anywhere in the world. Typically international shipping goes smoothly with a few caveats.

You'll be responsible for Duties/Taxes when the order arrives in your country. Typically you'll be contacted by the carrier to fulfill their needs to have your order delivered. Often times that means you'll pay a fee / tax.

Imported product must typically clear customs. This process is completely out of our control and can take anywhere from a matter of hours, to a matter of weeks. What's most helpful for you is to keep yourself informed of tracking updates.

You'll receive tracking when your order ships from our facility. We have as much information as you do when it comes to tracking.

We also highly encourage our International customers to purchase shipping insurance at checkout. Because of the unpredictable nature of shipping overseas, its a small cost for peace of mind knowing you'll receive your order.

Shipping Insurance?

We highly encourage our international customers to purchase Shipping Insurance at checkout. A small price to pay for piece of mind. If something happens to your order in transit, you'll be able to file a claim and undoubtedly receive your order.
