Quintano Roo Tri, 2009 ~

 

Triathletes won’t find a bike more suited to the challenges of triathlon than the 2012 Quintana Roo CD0.1. The CD0.1 gives athletes of all levels a true competitive edge by using wind as an advantage. Quintana Roo designers created the CD0.1 in the wind tunnel to achieve a groundbreaking bike Triathlete Magazine has called “the most innovative in the past decade from any brand.”

Twenty-five years ago, QR created the first tri-specific bike. Ever since, QR has pushed the envelope with forward-thinking designs that perform in the wind tunnel, but more importantly provide a measurable real-world advantage on the racecourse. QR SHIFT technology minimizes drag created by the drivetrain. QR’s exclusive 18mm offset down tube diverts concentrated, reconnected airflow off of the front wheel - away from the drive side - to the clean side of the bike. It makes perfect sense to use the clean side of the bike as a starting point for a frame design conversation. QR relishes the conversation that no other company is currently having: it’s about bike stability!

In the picture on the left, the green arrows show the direction of airflow separating, flowing, then reconnectin across the wheel. Note has the air is redirected to the non-drive or clean side of the bike once it reconnects. This is the real-world advantage of SHIFT technology.

 

Bicycles are asymmetrical objects. On the CD0.1, the diversion of the airflow to the non-drive side reduces drag from the drivetrain. This diverted airflow helps minimize side load from wind at wider YA angles. In wind tunnel tests, the side load data shows the CD0.1 with 50% more stability than the nearest competitor. The end result is that athletes spend less energy on steering correction and fighting wind gusts.

Note has the air is redirected to the non-drive or clean side of the bike once it reconnects. This is the real-world advantage of SHIFT technology.


Of course, all the aerodynamics and stability in the world are a waste if the bike is uncomfortable. Triathletes won’t find a bike with more fit capability and adjustability than the CD0.1. QR has chosen to use a standard 1 and 1/8" steerer fork design, stem, and base bar to provide nearly an unlimited range of options in bike set up. They have consciously chosen not to pigeon hole the rider into a proprietary cockpit set up that may not be ideal for your riding style.

 

Fast Talk from QR  ~

Racer Q: Why hasn’t QR integrated the front end of a bike with a bar-stem-aerobar combination like other “superbikes” on the market?
QR: We have made several different prototype designs with front-end integration. As of right now, none of those designs make the CD0.1 any faster in our testing. Couple
that with the need for a large number of athletes to pack their bikes in travel cases and the traditional steerer tube–stem–base bar combination makes sense. Also, we want you to have confidence that you can obtain any front-end part at any bike shop.

Racer Q: How does the improved braking design accommodate wider race wheels?
QR: QR pioneered a wide-wheel compatibility method with the release of the CD0.1. Additionally, we’ve improved brake pad adjustability in wide and narrow modes. Plus,
we drastically changed the leverage ratio of the latest calipers and levers. On top of the brake component improvements, we stiffened the brake mounting areas of the
frame and fork for even further braking enhancement.


Racer Q: Why so much adjustability in the saddle position of QR bikes?
QR: Professional fitters work with precise, calculated measurements when positioning athletes. The CD0.1 has the broadest range, with the most infinite adjustability. There are no limitations or dead spots in our position capabilities. This enables knowledgeable fitters such as Cycles BiKyle to fine-tune a more positive hip angle, which ensures the perfect balance of aero efficiency and power.
