TriRig's Alpha series of aerobars have set the industry standard for aerodynamics, adjustability, and design simplicity. See all the info below from TriRig:
ALPHA ONE: THIS CHANGES EVERYTHING
And now, we are completely changing the game. Introducing Alpha One: the world's first universal aerobar with continuous, vertical, single-bolt stack adjust. Alpha One is designed to fundamentally change the athlete's experience with their bicycle. Dialing in your fit is now as easy as loosening a single bolt. Tilt adjustments can be done on the fly. Pad stance is adjustable with twenty-one different positions on our ultra-comfortable Mini Open Back Arm Cups. Five integrated accessory mount bosses mean you can mount a BTA bottle, Garmin computer, or storage box with ease. And all of this is achieved in a package that's our fastest bar ever, while also being UCI legal. Get ready for a whole new ride.
Bike fit is an evolution, not a fixed target. Every athlete, from the first-time triathlete to the multiple world champion, changes their fit over time. Yet existing products don't reflect that reality. Even the very best bars out there require you to "hit" your fit numbers, and any adjustment afterward is a cumbersome and time-consuming process. You are now free to tweak and experiment with fit easily, with the turn of a single hex wrench. Find yourself in the middle of a solid training block and realize you could easily drop another 5mm lower? Try it out! Suffer a strained back and want to raise the bars for a bit? No problem. Alpha One lets you evolve your fit without any extra parts, and without any costly, cumbersome, lengthy trips to the mechanic.The Monopost can be trimmed if necessary to avoid interference with bayonet-style forks or head tubes. Replacement Monoposts are available here.
Universally compatible with all of our Dragnofly options. For building the Ultimate front end combine our Delta Aero Cover with the A1. If you are in search for added arm pad stack height check out our NEW Monopost with 140mm of travel.
For increasing your elbow to should width use our Wingspan Extenders or if you are trying to get your elbows super tight these will do the trick.
