Standard parts, incredibly clean lines. You'd be forgiven for mistaking this for a fully-integrated bike.

Okay, first up, that brake. It's our own Omega X, and as mentioned above, Orbea designed the fork/headtube/downtube complex from the brake surface back, keeping things as clean as possible. The aesthetic result is striking; the bike obviously looks like it was made for our brake. And yet despite this semi-integrated design, the brake still uses a standard single-bolt brake mount. So if you wanted (or needed) to swap the Omega X for something else, you could do so easily. Any standard mount brake will work just fine.

Speaking of that fork, you'll immediately notice the very wide bow-legged stance of the blades. The idea here is that moving the blades further from the wheel reduces pressure drag caused by the spokes on the top half of the wheel moving forward through those blades while the incoming air is moving backwards. The extra gap allows those two currents of air to move past one another with less drag. Orbea isn't the only player doing this; Dimond recently did the same thing with their new Superfork. And the idea indeed makes aero sense.

Moving upward, the entire fork/headtube/downtube complex is incredibly clean and minimal. A scalloped headtube uses a 1-1/8" bearing on bottom, and a skinnier 1" bearing on top, for a very slender frontal profile. The only drawback here is that 1" bearings may be a little more difficult to source if and when you need to replace it. But that's a small issue, especially when a lot of other bikes use custom bearings up front to accommodate their increasingly-complicated fork setups. Next to, say, a Speed Concept headset bearing, a 1" bearing should be comparatively easier to find. But it's perhaps not as easy as the dual 1-1/8" bearings on bikes like the Cervelo P-series, the Felt IA, etc. To be clear, Orbea keeps lots of them in stock, and tells us that most standard distributors stock them. Still, your local bike shop might not have them on hand.

Moving up further, that 1" fork accepts standard stems/bars, and the bike includes a shim for using 1-1/8" stems. It seems a bit counterintuitive that you'd use a smaller 1-inch bearing, only to shim back up to a 1-1/8" stem, but the reduction does indeed save a bit of frontal area in the head tube.

The top tube is raised to fair the back of the bar/stem area, and the bike even includes a fairing to clip onto the back of the stem, filling the gap between that raised top tube and the stem itself. I assume this fairing was designed with the included FSA stems in mind, it may not work with other aftermarket stems.

For this build, I took out a dremel and modified the fairing to fit with our Alpha X bars. The result was a very, very clean front end. I even took pains to do a bit of custom cable routing through the front of the top tube cutout, so that there's not the slightest bit of cable exposed to the wind. This build uses all standard parts, and yet has the look and aero pedigree of a completely integrated bike. I also swapped out our standard back plate for our optional NH Back Plate, removing the cable hanger and using the Alpha X's integrated cable stop up at the stem.

Finally, Orbea included a set of top tube bosses on that raised top tube, for storage mounts. If you have your bars slammed, this may not be the best option for storage, since anything put on that top tube would inevitably add frontal area. If you have your bars spaced up beyond the head tube, then the storage box makes sense.

Let's move backwards and check out the back half of the bike.

Orbea Ordu OMP 

The new Orbea Ordu OMP is a new bike that aims to hit modern superbike aero numbers without resorting to the increasingly-difficult mechanics of integrated parts.

Front End 

The Ordu OMP comes stock with Omega X brakes, designed to be a perfect aero match for the entire front end complex. We also added our Alpha X bars, which blend nearly perfectly into the raised top tube.

We finished the bike with a SRAM 1x11 drivetrain, Lightning cranks, Dash wheels, Dash saddle, and View-Speed bolt-on aero skewers. This beast is completely race-ready and 15.5 lbs as pictured (yes, including the disc wheel).
