Not exactly something for the 'weightweenies', TriRig have officially launched their new Omni frame. The design appears to draw inspiration from the Lotus 108 and 110 time trial frames of the late 1990s, albeit with more modern touches.
The seat angle is a steep 79 degrees, critical for triathletes looking to rotate forwards. It is unlikely that this bike will be UCI legal, however that is not the point of this bike. While only available in three sizes, TriRig offer a reasonable range of cockpit adjustment. From a shorter rider's perspective, the stack of 490mm should be low enough for most. I personally would prefer lower, but I ride 12.5-50km time trials, not ironman distance triathlons so I am obviously not their target audience.
Despite not being part of the target audience I am still excited by this product because it represents what could be possible if some aspects of the UCI regulations were relaxed. The aero data for the Omni has not been released at the time of writing, but I would be very interested to see the difference between this frame and UCI legal Cervelo/UKSI designs.
TriRig aren't the first manufacturer to design radically different triathlon bikes, Falco and Dimond have 'V' style designs focused specifically for non-UCI events. In terms of Geometry, all three of the mentioned bikes have a similar range between smallest and largest. Dimond offer 5 sizes for slightly smaller increments (but arguably this can be compensated for by stem lengths and spacers) and Falco offer slightly steeper seat tube angles (82 degrees).
The Omni is priced at $4990 for the frameset and $7990 for the complete build pictured above. It is interesting to note the choice of a SRAM 1x set up for the stock option. A surprising (but welcome) inclusion is the 4mm hex wrench from Silca which is required for the 'quick release' skewer. The complete build appears to be well thought out (though I can't really say more without actually working on the bike). Nothing stands out as something that can be a major annoyance.
Before wrapping up I would be interested to see how TriRig have managed the internal cable routing. I would suspect a few tight corners inherited by the bike's lack of down tube, but perhaps they've thought of something clever. If you're running electronic this won't be of much importance to you, though.
Not one for the weightweenies but I would suspect that most aeroweenies are impressed. I'm eagerly awaiting the aero results, how mast faster is this UCI illegal design?
