The Quintana Roo PRfour Disc 105 bike is part of a world-renowned triathlon performance line that comes in at a far lower price. Still, it features a ton of trickle-down technologies from the award-winning PRsix and PRfive. This bike has the same exact aerodynamic shape as these higher and more expensive models. It also utilizes the same SHIFT+ technology which was developed in the wind tunnel for prime aerodynamics. With boat tail foil and leading edge absent chainstay along with a design that pushes the wind to the clean side, this bike is great for cutting through the wind and setting new PR’s in your bike leg.

The aero frame of the PRfour is made with a hybrid of 24/30T carbon fiber composite which balances a lightweight feel and incredible stiffness while taking it easy on your wallet. The geometry of the frame features an oversized chainstay which adds to the stiffness and aerodynamic nature of the frame. A static aero downtube also helps the airflow move properly around the frame while offering more stability. This allows you to whip around corners and descents with confidence. This model features disc brakes which are lightweight, inexpensive, and reliable in all situations and weather conditions.

A practical design is a huge part of any tri bike and that goes for the PRfour as well. Its simple design makes traveling and shipping easy. Just two sizes of hex key are needed to disassemble the bike to get it packed up and ready for the road. You will have easy access to the QR Top Tube Storage Box which is available in two different sizes. This box is great for holding essential triathlon nutrition such as gels, base salt tubes, and electrolyte tablets. The storage unit is incredibly aerodynamic and tucks in right behind the cockpit. Another aerodynamic unit is featured on the tail and is great for spare tubes, CO2, and tire levers. Wind wraps around this unit to add stability. It is secured with a QBOX attachment bracket. The Quintana Roo PRfour is an excellent choice for the rider who needs a combination of performance and value.
