Omni - Features


Omni. It's everything we make, and everything you need. It is the sum total of all TriRig has learned and developed over the lifetime of our business. It combines all the features from our award-winning and Ironman-winning products, including Alpha bars, Omega brakes, Gamma extensions, and Beta bottle carrier, but that's just the beginning. Omni has an impressive list of features all its own. This bike is a complete solution that represents our best thinking on what a triathlon bike could be and should be.

Fit First

Of course, the most important aspect of any tri bike is fit. That's why the first input into Omni's designs were its geometric properties, including a true 79-degree seat angle and 72.5-degree head angle, 600mm front-center (for size Medium), and a centrist stack-reach of 525mm stack and 405mm reach. Combined with the ultra-adjustable Alpha One Aerobar, Omni fits the broadest possible range of athletes, from the aggressive long-and-low crowd all the way up to the conservative tall-and-narrow rider. Its fit range is centered around an orthodox fit range, making it the perfect ride for amateur and pro athletes alike.

Aero Supremacy

A bike that fits well is a threshold requirement, but aerodynamics is where the rubber meets the road, so to speak. In that sense, Omni is different from anything that has ever come before it. It's a true Monofoil design: the wind sees virtually no trailing edges as it passes over the frame. Our Monofoil was designed to take clean air from the front of the head tube, and guide it smoothly back to the rear wheel, avoiding interactions with the rider and cutting through the wind with as little drag as possible.

Innovate, Validate, Iterate

The design of Omni began with a simple premise: to attempt to guide the air passing over the bike as smoothly and efficiently as possible towards the rear wheel, away from the rider, and off the back of the rear wheel, causing as little drag as possible. Thousands of hours were poured into a coninuous cycle of design, CFD refine, wind tunnel validate, and repeat. Design was always a holistic process, incorporating the complete bicycle rather than just a frame and generic parts. Our Alpha aerobars and Omega brakes was always a part of the aerodynamic design, and the bicycle is faster with them than any other part. In fact, Omni is aerodynamically faster with its brakes attached than with no brakes at all! And throughout our design, we didn't forget simple first principles. There's a reason the catchphrase "narrow is aero" continues to abide. All things equal, less frontal area is better. Some newer bike designs seem to forget this, using straight (or even bulging) head tubes. We made sure to keep Omni narrow and clean, showing as little to the wind as possible.

Integrated Convenience

On other bikes, aerodynamic efficiency comes at the price of convenience. Not so with Omni. Everything you need to install, adjust, and maintain your bike is always within reach, starting right up front. Up front, our Delta front cover mates perfectly with the bars and frame. It's just one smooth form - no disjoint pieces or gaps to interrupt the air. And yet all adjustment bolts for the brake remain exposed for easy access.

Aero-Matched Skewers

Skewers are a nearly universally-overlooked detail that represent some very real wattage savings. Even the highest-end bikes still use enormous quick-release mechanisms that stick out into the wind, costing upwards of 4 Watts on a complete bicycle. Perhaps other manufacturers don't care, because the effects of a skewer isn't tested in the wind tunnel, where the skewers must be removed in order to attach the bike to the tunnel's fixture. But we took great pains to design skewers that perfectly complete the shape of Omni's fork blades, staying completely invisible to the wind. Our skewers bolt on, saving precious frontal area. But what if you need to take that skewer off during a race? You don't want to be wondering if you brought a wrench with you. So we designed a special storage slot in the back of the non-drive-side chainstay, which locks a wrench in place for easy access, while keeping it completely out of the wind. And we have partnered with Silca to include one of their pro-grade 4mm hex keys with every Omni. So you get the best of both worlds: the watt-saving speed of the aero-matched skewers, and time-saving convenience of the wrench.

Storage Done Right

This is how the storage box should be done. Rather than a large mass of rubber and plastic applied on top of the bike like a bandage, we integrate the shape of the box into the frame itself. So all you see is the top of the storage box, which fits into the frame like a glove. The box also acts as a fairing to the stem, and hides the cables on their way into the bicycle. Our Beta Bottle Carrier takes care of storage duties in back, keeping things clean and convenient. Many new entrants on the tri bike scene attempt to present the veneer of an aero pedigree without really tending to the details. But aerodynamics is truly a battle of "death by a thousand cuts," and the details make a difference. That's why we've tended to every last detail of Omni's aero design, including everything listed above, and much more.

Wind Tunnel Data

We are in the process of completing a formal study of the final production version of Omni in the wind tunnel. We will publish our data in early November. For now, we can show you this teaser, from an earlier study that compared our first SLA prototype to a leading competitor.

Simplicity Defined

The best tri bike is truly the triathlete's companion, offering convenient solutions to all of the needs the athlete has. The chief complaint with high-end bikes today is that they are difficult to use. Omni, on the other hand, could not be simpler. Virtually all of its components attach with standard interfaces, use standard fasteners, and are easily installed, adjusted, and replaced if needed. The bike breaks down easily for travel, and in the event of any travel mishaps, virtually every component can be replaced with standard bike parts. Need a different cockpit? No problem. Brake damaged in travel? Replace it with any standard road brake. TSA lost your aero-matched skewers? Standard skewers work, no problem.

No-Cut Fork

Omni uses a standard 1-1/8" steerer tube, and standard bearings. But Omni's fork has a couple of tricks up its sleeve, even beyond its aerodynamic prowess. The first of these is a patent-pending Hirth Joint system that allows you to make the fork longer or shorter without ever taking out the hacksaw. Omni includes five different toppers for the fork, providing a 0-40mm range of adjustment. Moreover, the fork topper eliminates the need for an expander plug. And although the integrated Omega brakes work brilliantly on the single-bolt standard brake mount, we added Shimano Direct Mount bosses in the event they are ever needed.

Easy Setup

A top-shelf bike shouldn't necessarily require a top-tier mechanic to use. That's why Omni uses standard interfaces wherever possible, and has dead-simple cable routing. A large bottom bracket opening serves as a place to store electronic wires and junctions, and the entry point for housing. Simply push all your cables and wires in from the large bottom-bracket cavity, and they will appear at the headset end, where a large opening makes completing the run simple.

Accessorize like a Boss

Wherever possible, we have added bottle/accessory bosses to Omni, allowing for easy attachment of hydration and storage products. Just forward of the seatpost you'll find a pair. There's another pair on the rear surface of the seatpost itself. The seatpost also has a pair of bosses corresponding to Shimano's Di2 battery mount, as well as a cable port for electronic wires. There's a second set of Di2 battery bosses on the non-drive-side chainstay, offering yet another option for setup. Omni ships with our Beta Bottle Carrier, which provides an additional three sets of mounts. Even Omni's storage box up front is affixed using this standard. And of course, the Alpha One aerobar has BTA mounts on the Dragonfly. That's a total of seven sets of bottle/accessory bosses and two sets of Di2 battery bosses.

Devil in the Details

There are a number of small but important features all over the bike that add up to a big difference in terms of simplicity and usability.

  • Optimized for 1x or 2x: We love 1x drivetrains. That's why we designed Omni with a removable front derailleur hanger, and a replacement plate that completes the aero shape of the frame when the front derailleur hanger is removed.
  • PF30 Bottom Bracket: PF30 is simply the best standard out there. It accepts every crankset on the market, installs with ease, and uses readily-available parts. It's simple and effective.
  • Vertical Dropouts: Vertical dropouts offer greater convenience and ease of use compared to horizontal ones. And because we optimized Omni for wide rims and large tires, there's no real need to use smaller tires and then adjust the wheelbase inward as you would with horizontal dropouts.
  • Replaceable rear derailleur hanger: In the event of a crash or travel mishap, the rear hanger can easily be replaced.
  • Rear-facing cable exit: The rear derailleur cable exits horizontally, out of the wind. Most bike makers point their cable exit upwards into the wind. Not so with Omni.
  • Single-bolt seatpost clamp: We love wedge-style seatpost clamps, which offer a secure grip on the seatpost without showing anything to the wind. One bolt, done.
  • Complete Integration: All parts were designed together, to hide cables, preserve access to all adjustment bolts, and retain completely standard interfaces everywhere. It functions and adjusts like a standard bike, with all the aero pedigree of the most advanced superbike.

The Perfect Ride

Of course, all the trick aero integration doesn't matter if your bike doesn't steer well. So how does Omni measure up? Quite simply, it's a dream. We've ensured that you'll stay comfortable and in control, so you can stay in the aero position all day and never worry about handling or comfort.

Large Tires Welcome

Omni was not only designed to accept wide wheels and tires, it's aerodynamically matched for them. We designed the bike to be fastest with 23c or 25c tires, front and rear. This gives the athlete to run lower pressures for greater comfort while keeping rolling resistance to a minimum.

Perfect Handling

You may notice that Omni's geometry is essentially middle of the road, a perfectly orthodox fit. Combined with the wide range of adjustability included with Alpha One aerobars, it will let you hit any position and still ride beautifully. Omni's ride is plush, predictible, and enjoyable, so you can focus on your power output and not on twitchy steering.

ISO Tested, Trainer Friendly

Some unconventional bikes warn you not to use them on a trainer, for fear of cracking. Not so with Omni. The bike has been tested to over 120% of the most rigorous standards in the world, the current ISO strength and fatigue standards, and passes with flying colors. Use the bike on a trainer, out on the road, or anywhere you want to ride, knowing that the bike has been tested safe.
