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. Dialling 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 Ergo 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.
The Alpha One base bars are supplied with Gamma One carbon extensions.
MONOPOST STACK ADJUSTMENT - Alpha One's patent-pending monopost design allows you to achieve continuous, truly vertical stack adjustment from slammed to stacked in just seconds, using a single bolt that's always accessible at the front of the bar.
INTEGRATED TILT ADJUSTMENT - As more and more athletes have begun to discover the benefits of arm tilt, TriRig has been on the forefront of developing products that integrate it. Alpha One offers tilt of -10 to +17.5 degrees. Tilt is available at all stack heights, and can be adjusted at any time with two bolts between the arm cups. The bolts are always accessible and use the same 4mm wrench found everywhere else on the bar.
ERGO CUPS WITH 21 POSITIONS - Alpha One offers twenty-one different positions for the cups, including seven stance width options, and three reach positions. There's simply nothing else on the market that offers this level of granular refinement. And everything on the bar adjusts independently; whether adjusting your arm cup, your extensions, your stack, or your tilt, everything else stays in place, and no bolt is ever occluded.
MOBILE BIKE FIT - For too long, fit has been about hitting a fixed target. Alpha One completely changes the game by providing you the entire adjustment range of a fit bike in a functional, on-the-road aerobar. Adjust stack, reach, stance width, extension position, and arm tilt, all with a few always-accessible bolts. Make the fit work for YOU rather than the other way around.
ULTIMATE CONVENIENCE - Everything you need is included in one package, and every bolt on the Alpha One adjusts with the same 4mm wrench. So whether you're making tweaks at home, or out on the road, you'll never have to dig around for multiple tools.
ACCESSORIES GALORE - The integrated BTA mount features five M5 bosses for installing bottle cages, computers, or other accessories, in whatever configuration and combination you like. As with everything on Alpha One, these bosses are always accessible, and let you configure the bike to your preference.
This is a game-changer for bike fit. You can finally think of fit as an evolution rather than a fixed target, allowing fitters to prescribe a range and describe a process, instead of the decades-old and outdated "this is it" mentality of other bars.
Up to 40mm of aero-matched spacers improves the fit range to a total of 120mm of stack adjust, while maintaining superlative aerodynamics and industry-best cable routing.
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.
