My TriRig Omni: Build and Review

After over a year and 10,000+ miles of riding, it’s finally time that I wrote a thorough review of my bike, the TriRig Omni. Since first building it up in June of 2019, I’ve had my best results to date despite the debacle that has been 2020. I know the ins and outs of this bike extremely well, and have finally settled on a build and fit that likely won’t be changing any time soon (despite my love of tinkering). I also like to think that I have the most outdoor miles ridden on this bike than anybody else, though I have no proof of that!

I’ll start with the obvious. In case you haven’t noticed, this bike is a bit different. Even by triathlon super-bike standards. Most notable is the lack of both a downtube and seat stays. Like many aspects of this bike, this is primarily to do with improved aerodynamics. The removal of the downtube works in two ways. By reducing the area exposed to crosswinds as well as eliminating the turbulence created between the front wheel and a down tube. So it is not only more aerodynamic by itself, but also due to increased stability allowing me to hold aero in worse conditions. This became readily apparent in my first 2 races on it with a super windy Eagleman 70.3 and IRONMAN Ireland in ridiculous conditions!

The removal of the seat stays offers another place allowing air to flow freely rather than hitting another solid object following the rider’s legs. Many companies have done similar things in lowering the seat stays to reduce the frontal area to the wind, but TriRig did away with them completely all in the name of aerodynamics.

Continuing with the theme of aerodynamics, this bike is extraordinarily narrow. It’s hard to describe this without seeing the bike first-hand, but it is easily the most narrow triathlon bike I have even seen or ridden. There’s still no issue fitting any 25mm or even some 28mm tires with enough clearance. Though I tend to choose either 23mm Corsa Speeds or 25mm GP5000 TL’s depending on the course. They also fit the profile of my DT Swiss ARC 1100 wheels perfectly. I’ll also vary between DT Swiss’s 48mm, 62mm, or 80mm depth wheels depending on the course and conditions for the day. All of which are super aero and fully kitted out with ceramic bearings of course!

The brakes for the front and rear are both TriRig Omega X aero brakes. These brakes are one of TriRig’s premier products and are what really drew me to the company in the first place. They are simple to use and adjust, as well as functioning perfectly with a ton of bite. They offer the best braking outside of disc brakes, but without the downsides of added weight or worse aerodynamics. The front brake is even covered by TriRig’s Delta cover which completely cleans up the front end and any cable from showing at all.

What the Delta cover attaches to is another one of TriRig’s main products, their Alpha One aerobars. These are not only super quick bars, but also extremely easy to adjust. I don’t frequently change my fit on my front end anymore, but it still makes it super easy to disassemble for packing. It hides almost all my braking and Di2 shifting cables but wasn’t crazy hard to install either. I personally currently use TriRig’s closed back scoop arm rests to lock in my position exactly where I’m comfortable. I have these angled at about 12.5 degrees and run the Gamma One extensions which keeps my wrists in a relaxed neutral position on the bars.

Just behind the aerobars hides a bento box that can be used for a variety of things. For my long rides I’ll typically use it for salt tablets or a multitool, but for races I may use it for either gels or trash storage.

Moving down to the drivetrain things get a bit more unique. I have been running an Infocrank crankset since 2017 and currently have 165mm crank arms, Speedplay Aero pedals, and one 54-tooth SRAM chainring. The Omni is perfectly suited to run this one chainring (1x) set up as you can remove the front derailleur hangar making it super clean. I’ve dropped my chain twice since making the change to 1x over a year ago, both times after particularly large bumps. And otherwise this has been a great change for increased aerodynamics and ease of use.

I recently moved to using SLF Motion for both my bottom bracket as well as using their derailleur cage and oversized pulley wheels. I have this set up on an Ultegra 8050 electronic rear derailleur. Although I don’t have a ton of miles on it yet, it has been working great so far and meshes perfectly with the rest of the system. I’ll run anywhere from a 11-25 to 11-32 cassette for races depending on the course, and also throw on an ICE Friction chain for the really big races! I had a fresh one for my 413 mile ride and it still looks like it has some more life to it!

Moving up the bike, I have a Berk Dila saddle mounted that is super comfortable for me in their padded 143mm wide version. It weighs in at exactly 103 grams which is a huge bonus whenever the road tilts up. Berk did a custom lettering for me in gold which was a nice touch! Sitting just behind the saddle is the TriRig Beta bottle carrier where I’ll frequently have anywhere from 1-2 Kappa cages. This will depend on what I need on the day, but these cages grip the bottles super well making accidental ejection almost impossible.

Now that we’ve covered all the physical hardware, what is the ride quality like? Despite the lack of a downtube and seat stays, it is still surprisingly responsive. When in race ready mode (without fluids) the entire set up weighs in at about 22 pounds. Which isn’t super light compared to a dedicated climbing road bike, but pretty good compared to most other triathlon bikes I’ve ridden in the past. When switching from my prior bike (a Ventum), the Omni had a much snappier response, especially when accelerating or climbing. I certainly wouldn’t expect to be doing any crazy sprinting on it, but would put that down to my position on the bike as much as the characteristics of the ride quality. It’s a pretty smooth ride as long as I’m not going over cattle guards, especially when dropping the tire pressure to 80psi or below. It’s also fairly resistant to cross winds as I mentioned earlier. Though I would still opt for a shallower wheel on a windy day with gusts over 25mph, especially in the mountains where you can be caught off guard.

The final build (plus reflective stickers)

And that’s pretty much it! If you have any questions for me about the bike then don’t hesitate to reach out. I’m looking forward to crushing some more bike splits on my Omni once racing finally resumes. And I’m still hopeful that this bike will one day hold the 24 Hour TT World Record, though that one is going to take a lot of work!

I wonder which size she’ll ride?
