Frequently Asked Questions
  • What is the production status and development history of Alpha One?

    Development of Gamma One, Gamma 24, and the Aero Bar Plugs is finished, and we are now shipping the extensions! Get yours right here.

    Update, May 4th, 2018: The second small batch of Alpha One bars has shipped to the next preorder customers in line. We expect to send out a few more sets next week as well. If you are in these batches, you will receive an email notification asking for a confirmation of your shipping address. We are continuing to work hard to get all preorders out as fast as possible, and by mid-June we expect to have bars in stock for regular orders. Thanks for your patience, and we are very excited to finally get bars out to customers!

    Update, April 9th, 2018: We are delighted to announce that the first small batch of Alpha One handlebars has already been shipped out to the very first customers around the world. However, there are still many preorder customers who have not received their bars yet. We are working hard to get the next (larger) batches of production finished and sent to customers. The very next batch should satisfy most of the remaining preorders. The factory has told us that this second batch will be ready by mid-May, but we are working hard to accelerate that deadline.

    Update, March 29th, 2018: The finish line is finally here. PRODUCTION IS COMPLETE on the first batch of Alpha One aerobars, including all packaging and hardware. Everything is on its way to TriRig HQ for final inspection, assembly, packaging, and shipping to the earliest Alpha One customers. If you are one of the customers in this batch, you will receive an email next week to confirm your shipping address.

    For those of you who ordered an Omni with Alpha One aerobars, the final piece of the puzzle will be the universal front brake cover, pictured below. This piece has had its mold completed, and will be on to testing soon (a much shorter process than with the carbon parts), and then production. At first, it will ship pre-cut for our Omni customers. Eventually it will be available uncut, as a standalone purchase, to help make any standard bike more aero. It is an extra-long fairing that is trimmed to length for your particular bike, then assembled with our Omega X brake and Alpha One (or Alpha X) aerobars for the perfect front end. More news on this part soon!

    Update, March 8th, 2018: Production has begun on all carbon parts. All hardware and fasteners are complete and ready. Packaging is printed and assembled. We are working hard to get the first production batch finished before the end of the month, and on to the first customers by early April.

    And at the same time that the production side has moved forward on the bars, we have been finalizing the design of the Front Brake Cover that mates with the Omnibike. You can see the initial version of this design at the end of the Alpha One launch video. The initial design of the cover was specific to Omni, and not compatible with other bikes. But we've worked hard to make the system universal, so that it should be compatible with almost any bike with standard head tubes and brake mounts. It will come extra-long, with a trim guide, so you simply cut to length for the size of your particular bike. It mates up with Omega X, and either Alpha One orAlpha X. Lots more details coming soon.

    Update, Feb 24th, 2018: All layup and testing is complete. All parts are finalized. We are making some minor revisions to the mold to reflect a couple of fitment/tolerance adjustments, to ensure a nice tight fitment on all parts. This process will take a couple of weeks, and then we will proceed to production. The first batch of bars should ship in early April, new orders are projected for late April or early May. The finish line is almost here! Thanks everyone for your patience.

    Update, Feb 7th, 2018: Layup for the Base Bar and the Monopost is complete, and these parts have passed ISO strength and fatigue testing. The bars are stiff, strong, and reliable. We are finalizing layup on the Dragonfly cup mounts, to ensure that their connection to the post and their stiffness and strength match what we have come to expect with the rest of the bar. This process is nearly done. After that step, it will be on to full-scale production.

    Update, Nov 25th, 2017: We have been hard at work on Alpha One for over a year. After initial modeling of the concept, our first prototypes were 3D printed plastic, to get a sense of fitment and function at a very high level. After more refinement, we produced fully-functional prototypes in metal, to fully prove and test the mechanical concept. These were so-called "Aero Or Die" prototypes, which lacked the base bar wing section. Here are some images of those prototypes (you can also see a 3D-printed version of the integrated brake cover for Omni):

    The mechanical concept was sound. The bars functioned as we had hoped, were solid, didn't slip, and adjusted easily. So following the metal prototying phase, we moved on to aero refinement. For months, we worked on finding every last gram of drag we could eliminate from the bar. Once we had final shapes for everything, it was time to cut molds for production. These molds are complete. Below are pictures of some of the first pre-production samples from the carbon molds:

    We've already machined and finished all the small hardware for the bars, purchased all the fasteners, and finalized packaging. Currently, we are working on final carbon layup, doing final mechanical/safety/fatigue testing, and then we will move on to production. This is sometimes a relatively fast process, and sometimes it can suffer delays.


  • You say that Alpha One is faster than Alpha X. Is that really true? What about Alpha X's super-deep airfoils?
    Yes, Alpha One is genuinely faster. Not by much. Our CFD studies show it to be about 10g faster on average (across a variety of stack heights and setups). This translates to a savings of about 1 Watt. In the wind tunnel, you likely couldn't detect a difference that small, reliably. It takes good CFD to really test differences this small. The bars would look like a wash in the wind tunnel.

    Our goal with Alpha One wasn't to make a significant aero savings, as Alpha X is already a VERY fast bar. Our goal was not to make Alpha One slower, so that it wouldn't be a compromise to utilize its exceptionally-flexible fit system. And we succeeded. It's consistently faster than Alpha X in all the configurations we tested.

    The reason we were able to get away with a shorter airfoil section on the base bar wing is not a simple story to tell. Suffice it to say, we tried a LOT of shapes for the aerobar wing. Some were very deep, more like Alpha X. Yet the deeper wing sections did not make a faster complete bar. There are lots of little interactions where the wing meets the stem, transitions into the top and sides of the stem and Monopost, etc. The shallower 3-to-1 sections worked better at preventing those little interactions from getting messy and creating drag on this particular system.

  • I want to purchase the Omni bike, with the Alpha One bar. How can I do that?
    Go ahead and purchase your Omni. Then just send us a note telling us you'd rather wait for the Alpha One. We will ship the remainder of your frameset, without a bar, and send the Alpha One when it's ready. No charge. You will also receive the Omni-specific cable cover when ready.

  • How strong is the Monopost system? Will it slip if I go over a bump?
    This was one of our chief concerns along the whole process of development. And it was one of the big questions we wanted to answer when we developed the metal prototypes pictured above. In short, the system is solid. We couldn't get it to budge in our initial testing. Here's a short video of some very informal (non-scientific) testing showing me jumping up and down on the bars trying with all of my 160 lb frame to get them to move. Of course I'm not the heaviest athlete, but I'm also bouncing from a substantial height.

    We are working to ensure the carbon version works just as the alloy prototype did, and we have more formal testing equipment at the factory to quantify the strength of this connection. But we are confident that it works very well.



  • How are cables routed on the Alpha One? Can I hide my Di2 junction box in the cavity?
    Cable routing through Alpha One is easy, straightforward, and hides cables from the wind. The brake cables route internally through the wing. The front brake cable exits the opening at the bottom of the bar, and you can route full housing or hydraulic line through the hole, or route bare cable via the included removable cable stop. The rear brake cable exits the back of the bar under the cable cover.

    Shifter cables or wires exit your extensions, and enter the stem cavity. They are then hidden under the cable cover, by entering the cable port just behind the Monopost. You can route all your cables and then hide them, rather than have to execute a convoluted routing operation with the cover already in place.

    The images below show routing with Shimano Di2 wires, and full brake housing. And yes, the 5-port Di2 junction does fit in the stem cavity. It's a tight fit, but it works. The routing would be the same for mechanical cables, except that the shifter cables would not be taped to the back of the Monopost, instead taking a slacker route to the cable port behind the Monopost.
