I honestly think my Quintana Roo PRSix Disc is the most awesome triathlon bike in the world. The aerodynamic, the response and the hassle-free use are the main reasons for my claim. It was totally awesome as it was, but I still choose to upgrade it slightly.
The Xlab aero bottle is replaced by the TorHans VR. From a practical point of view I like the Xlab bottle better, but Matt Hanson, tested the TorHans VR bottle to be 2,4 watts faster on an identical frame. Needless to say, aero triumphs practicality any (race)day 😉 Another bottle change up is an Xlab Gorilla XT cage, the strongest bottle holder you can get, in the rear to ensure I don’t lose a bottle. The King cage in titanium is very good, but I did lose a bottle during a rough patch of the road during Patagonman and can’t let that happen again. I moved the cage in front for a BTA solution.
After using countless hours in not succeeding to set up my tubeless setup I gave up tubeless. The main reason turned out to be a construction fault on the front Enve rim making a leak inevitable, but regardless, it was a pain to set up. Now I run GP5000 clincher tires with Silca latex tubes inside. The front wheel has a 25mm tire which measures 27mm and the disc has a 23mm tire measuring 26mm. It might sound a bit strange, but I measured the 25mm tire as wide as 28mm on the Roval disc making it exceed the width of the rim, which probably is less aero. The aerodynamics of the front wheel with a GP4000 25mm is well tested by HED.
The biggest upgrade is still the gearing. From a Sram Red eTap 2x to the new Sram Red eTap AXS 1x. Less weight, better aerodynamics, and one component less that can fail. Only win-win, at least if you got the power to push a 50t front and 33 rear combo. You can also get a 48t front chain (and soon a 52t).
