Since it seems that all the best tri bikes are getting disc brake versions lately, Dimond is showing their hand as well. Mixing it up on the big island with the bigger bike brands, Dimond has launched their latest version of the Marquise – complete with a new braking system.

Dimond Marquise shines brighter with disc brake version in Kona

Starting with the same frame design as the rim brake Marquise, the Marquise Disc moves to flat mount calipers front and rear for improved braking. To keep the wheels in check and provide perfect alignment, 12mm thru axles are used front and rear. Details are still pretty limited, but the press release hints at bigger tire clearance thanks to the lack of rim brake calipers as well. Each frame still includes their integrated Lunchbox and TOTES storage for carrying your supplies needed for a 112 mile ride.

The first bikes are on hand in Kona and available for test rides, with production models only available for pre-order, with delivery in January 2019. Each frameset is priced at $7,499 which includes custom paint. Complete and custom builds will also available through Dimond’s website.





  1. No, Specialized invented all that stuff! (please ignore Zipp 3001, Softride, TitanFlex, Kestrel 4000 and a few others)….

    Good on DIamond to fill a niche that is certainly there. Still cant figure a valid reason for a seat tube on a Tri bike.

    • Aero is for the very most pointy end of the field. For the rest of us comfort is key, and not being ‘beaten up’ by the bike. Seems frames got stiffer and stiff for years. Now, for relief folks are going to wider tires with less pressure. This does not matter a lick for most US riders and most US Tri folks. 112 Miles is another story all together.

      The line ‘suspend the rider, not the wheels’ was I want to say a Softride/Alsop thing. If you talk to a TitanFlex or owner of another beam bike you will hear the same stories about comfort due to the inherent suspension.

      Comfortable (in the seat) is far more valuable than a stiff bike that beats one to hell on chip-seal. I have ridden 112mi a time or two, then gone for a run…both on beam and ‘diamond’ bikes (as in the shape, not the brand). I would prefer to be on a beam any day.

      • Actually, aero concerns are significant even for those not at the “pointy end”. Whether comfort or aero are “key” is a subjective question, not an objective one. Being aero does not preclude being comfortable, especially since there is no objective measure of comfort.

        • Robin – the fact is, MOST of the MOP and even FOP folks playing 146 games would be far better off getting coach than they would ‘investing’ in “aero”. Then then there are folks (many pro’s) who if given a FREE bike will opt for a Cervelo P2 over a P3/4/5 due to the geometry of the bike (comfort). If you are not comfortable in your ‘aero’ position, you will not be aero for long. This can be seen at any triathlon of your choosing if you want to spectate.

          • Sorry, I didn’t attend your acronym class. Most? Maybe, maybe not. That has nothing to do with the original claim, which was completely subjective, i.e. product of your own assumptions and biases, not demonstrable facts. None of that addresses at all the fact that aero benefits are seen by virtually all riders. Are the other ways for riders to go faster and to possibly to possibly to so by sending less money? Probably, but that has nothing to do with the aerodynamics of this bike.

            I suspect your assumptions about what pros would ride is based on nothing but imagination and personal bias, so I’ll give that claim credibility reflecting as much.

            • Pro’s ride what their sponsors pay them to ride. ‘Best’ is the bike from a sponsor. Oddly, None of the recent ‘super bike’s won at Kona a bit ago….huh.

              • So you apparently don’t think that Wurf’s bike is a super bike. Do you get that the rider pedaling the bike has some influence on performance?
