Quintana Roo professional and age-group athletes have had huge success in their recent 70.3 and IRONMAN events, all taking the first spot on the podium. We’re extremely proud of each of these athletes for their performance & dedication to keep pushing to the front of the pack.


Quintana Roo age-group athletes Meghan Fillnow and Mike Vanacora prove that you don’t have to be a professional athlete to win races, or put out fast bike splits. Meghan and Mike both won their age-group divisions at IRONMAN 70.3 Ohio, with Meghan (F35-39) finishing in 4:37:17 and Mike (M30-34) finishing in 4:04:36.

Both Meghan and Mike ride QR’s PRsix superbike – it’s light, agile and aerodynamic in a way that reinvents expectations for triathlon bikes. Read what they had to say about their experience riding the PRsix.

“I’ve had an amazing experience on my Quintana Roo PRsix Neutron bike. Not only do I love the hot pink frame, it’s also super comfortable and aerodynamic. This is hands down the best bike I’ve ever had. My bike times have increased substantially this year, and I really owe it to this speedy bike! Not only is the bike top notch, but something else that separates Quintana Roo from other bike companies is their superior customer service. Their kindness, care, and responsiveness is sensational. I highly recommend getting a Quintana Roo bike! 

I recently raced Ohio 70.3. I came out of the water 49th female, and moved up to 2nd female off the bike. My power numbers were 15 watts higher than they’ve ever been in a 70.3, and I hit my fastest bike split. I was able to run down the top female and came away with the overall win. It was fun seeing that the overall male winner was on a Quintana Roo bike, as well!”

"I have been riding the PRsix since mid-2017. This new ride has been nothing short of amazing! The Di2 is a game changer and shifting from both the aero and bar ends is incredibly convenient. This makes continued adjustments on long up-hills painless and allows me to better fine tune my cadence.

In my first race with the new bike at Kona last year I dropped 24 minutes in my Ironman bike ride and felt great getting off the bike. This success has continued into this season as I have finished in the top 4 overall at every race and PR'ed my ride on two separate occasions. I have always enjoyed the bike leg, but never felt the results showed what my power numbers and training rides suggested are capable, that is until this season.

My journey in this sport is relatively new, but with a strong performing bike under me I am starting to set my goals on become one of the strongest amateur riders in the world. Thanks to Quintana Roo who has helped me in this journey!"

Brent McMahon walked away a champion after IRONMAN Canada! He led the race all day, with Andrew Talansky, former UCI World Tour rider turned triathlete, following shortly behind on the bike. Brent broke the tape with a finish time of 8:31:33. As a Canadian, there is no title more notable than being the winner of IRONMAN Canada in the triathlon world. 

IRONMAN Canada has one of the most scenic and challenging bike courses on the North American circuit, with an elevation gain of 2,579 meters. Brent's Stealth PRsix Disc allowed him to keep fresh legs and run the fastest marathon of the day at 2:53.

Congratulations, Brent, on this amazing achievement!


cal millward

Cal Millward of The Cupcake Cartel took the 1st place finish at IRONMAN 70.3 Boulder! It was a hard-fought battle on a tough course, but Cal came out on top with an epic finish at 3:47:04.

After finding himself 4 minutes behind the leader in a tough field of athletes coming out of T2, Cal found it in himself to catch the pack and sprint to the finish line for the top spot on the podium. Congratulations, Cal, on an outstanding performance!

Sizing & Fit


At Quintana Roo, we develop our bikes with a wide range of adjustment so riders can find the perfect position that is both comfortable and aero.


View our size charts to see what size is best for you. After purchasing a new QR our product team will reach out to you to confirm your order and sizing information to be sure you have selected the optimum size.

If you're on the border of two sizes, the right size may depend on certain body measurements and your riding style. Feel free to contact us at any time regarding sizing questions - our product specialists are experienced with finding riders the right fit by cross-referencing your information with our QR Rider Fit database. 

If you're not transferring measurements from a similar triathlon specific bike, to get completely "dialed in" for maximum performance, we recommend you see a reputable professional bike fitter that can fit you to your new Quintana Roo.
