Shopping for race wheels is confusing. Manufacturers have multiple lines and within each line they often feature multiple profiles with minute differences indicating a specific breadth of use. It almost seems like you need to buy 6 different wheelsets to accommodate every riding condition imaginable. And, well, that's not feasible for most of us. The Reynolds RZR series consists of only three wheels. Yet, it is a dedicated and diverse series that utilizes the latest Reynolds innovation. The RZR 92 focuses on deep aerodynamics for races against the clock, while the RZR 46 is a non-UCI approved, sub-1000 gram lightweight terror. This leaves the RZR 46 TEAM Wheelset as the go-to UCI approved wheelset for the world's top riders. The complexity of the RZR design is deep, so we'll break it down into pieces. To start, we need to understand the prevalent ideology in aerodynamic wheel design, and to do so, we need to understand drag. What is it Simply put, it's the restraining force that acts on the wheel when its direction of motion is counter to the free stream of airflow. Now, airflow near the surface of a wheel is turbulent by nature, and when it comes close to the rim surface, it becomes a turbulent boundary layer. This is the start of two kinds of drag, skin friction and pressure drag. Currently, wheel makers are attempting to harness the turbulent layer, closing it at the rear section of the rim. The reasoning behind this is that the system reduces pressure drag, but in return, the wheel sees gains in skin friction. However, this is viewed as a positive trade off, as skin friction has around a ten-fold lower drag value than pressure drag.As technology develops, engineers are forced to develop more efficient airfoil designs, and these designs take the shape of what's called a NACA profile -- think of a stretched out tear drop shape. In recent years, though, some wheel designers have started to view the NACA profile as insufficient to the aerodynamics of wheel...
