In 2014, Diamondback presented a new theory on aerodynamic bicycles with the Serios TT/Tri bike. It used thicker than normal tube shapes to control the wind, rather than the popular waif-thin blades. Now, they’ve blown all norms out of the water to rocket from T1 to T2 with the all-new Andean.

Designed with aerodynamicist Kevin Quan, it presents the Aero Core concept, which says that the wheels are the most important part of the aero equation. Once those are selected and tires are installed, the best thing you can do is to fill the space between them as much as possible. Of course, a solid sheet would be hell in crosswinds, so they combined Quan’s experience with Dr. Phillippe Lavoie and his grad students at the University of Toronto Institute for Aerospace Studies (UTIAS).

The concept started out in the UTIAS wind tunnel at half scale to prove the concept. In testing, they found that it was fastest with all of the storage compartments in place:

The gray line shows the Serios with HED Jet 6 front and Jet 9 rear wheels, with Continental Attack 22mm front and Force 24mm rear tires installed. The blue line shows the new Andean with the same cockpit and build as the Serios, without its storage compartments installed. The red line details the drag up to 20º yaw angle (cross wind) with everything installed as shown in the top photo, save for a Jet 9 front / Jet Disc rear wheel.

Final wind tunnel testing was done around HED Jet 6 wheels front and rear, with 24mm front and 26mm rear tires. The Aero Core concept fills in the gap between the center of the wheels, where the most turbulence is, with as much frame as possible. This also essentially takes the crankset out of the crosswind equation. They say the design gave them excellent drag reduction throughout the tested yaw angles.

Supercar aesthetics aside, there are a ton of useful features built into the bike that take full advantage of the massive fuselage.

Tool storage hides inside the main frame with a pop-up “gas cap” style cover.

Food, fuel and other nutrition can be stashed in the bento box section behind, on top of, and in front of the stem, which is hidden from the air by a horizontally placed water bottle.

The Diamondback Andean will make its formal race debut at Ironman World Championships in Kona.

2017-diamondback-andean-triathlon-bike-pricing

It will be available directly from Diamondback only. The move, they say, to direct-to-consumer for this model is two fold. First, it lets them offer the super bike at a better price, making it somewhat attainable. Second, it lets them work more closely with the end user to customize the build and preferences and improve the overall experience. We’re guessing it may also be a move to increase their reach beyond the existing dealer base. Prices start at $4,779.99 for the base build, which is in no way low end, and moves up to $8,069.99 with Dura-Ace Di2. Click the spec/price sheet to enlarge for all the options.

Want one? They’re taking $500 non-refundable deposits now for delivery in January 2017.

I read this and then looked at the picture again. I think you might have a pretty valid point. I’d like to think they took the front wheel off and lopped the bottom storage so that it isn’t the low point but it is hard to tell if that’s true or not.

may have to transport w/ the front wheel on?

There is no way this would fit on a fork mount tray, at least not the ones I have owned. Draw a line from the rear wheel to the front axel and you have what looks like 6 to 7 inches of frame that would go through the tray.

Honestly, this is rad as heck. Good on ya Diamondback for doing something! As much as “regular” bike riders like to disparage tri people and their bikes (stereotypes do exist for a reason though!), the fact remains that there’s some radical engineering and design that goes into this stuff. Wonder how different the response would be if the bike said “CERVELO”, “CANNONDALE”, or “LOOK” on the down tube?

Do you think Eddie Fiola could air this at 11 at the pipeline like he did on his GT? ( for the oldschoolers )

The out of the box build quality of every Diamondback I’ve ever seen has been appalling. The rationale to make what’s probably the hardest to work on bike with (probably) terrible build quality direct to consumer is baffling.

Nice to see them push the limits; shame their business model doesn’t match their engineering.

Matt Pewthers

I really like a lot of the bikes that Diamondback has done over the past several years, especially the Haanjo Carbon bikes this year, but I have to agree with you. The 3 DB’s that I assembled during the past two years (the REI that I worked at didn’t stock them, but a few got ordered through us) required some sort of action; 1 Airen was missing a cable guide, and 2 Insights required new BBs in order to get the chain line right (not all cogs were usable from the middle ring). They company was, however, accommodating and easy to work with.

The price seems competitive enough that they should be able to bump it up a bit to give consumers the security of going through a dealer.

FWIW – I have a Haanjo Trail and Sortie 3 and didn’t find much wrong with either one. It really wasn’t different from having any other bike shipped to you in a box. Whatever ‘out of the box build quality’ even means. A derailleur mount looked to have gone on while the paint wasn’t completely dry on the Sortie. That was ALL I could find wrong.

When things are simply created to create a larger equipment imbalance at trip events it deserves to be bashed. Just because you can do something doesn’t mean you should. If you can explain in any sane logical manner how this bike improves the sport of trip other than creating a greater equipment advantage between certain riders I’d love to hear it. But i bet you can’t and neither can DB. 🙂

I have no doubts this bike is really fast and possibly even the fastest thing out there. But disc brakes are surely a major compromise. I’m sure they did everything they could to negate their drag but there’s no way in hell that they don’t produce more drag than designing the bike without them. Ha, plus, triathletes have enough trouble changing flats with quick releases and rim brakes. This bike is gonna create a lot of big time losses for age groupers. I 5 minute flat fix(not abnormal for triathletes) will result in 10 minutes of trying to get the wheel out, then giving up and waiting for neutral support where they’ll do the flat fix and you get a time penalty as a side gift.
