Technology

Technology of Parcours Ronde Carbon 35/39mm. Disc Wheelset

#thinkwider Project:

When testing aerodynamic performance, there are three main tools that are used:

1. CFD (computational fluid dynamics) simulations
   
2. Velodrome testing
   
3. Wind tunnel testing
   

With each of these methods, the test subject (in our case a wheel) is tested in a controlled environment, either physical or virtual, under specific, controlled wind conditions. Wind speed can be scaled mathematically, to show drag (and other forces such as sideforce) at a range of speeds. However, the wind angle, known as the yaw angle, remains fixed, with the resulting drag value being specific to that angle.

In real world riding conditions, of course, the wind direction is rarely if ever stable and constant, so we need to be able to translate test results from fixed yaw angles to the more variable conditions encountered whilst riding. To do this, we need a dataset for "average" wind conditions, especially wind direction / yaw angle.

There are several such datasets already in use across the cycling industry. The simplest takes the average recorded wind conditions from UK Met Office weather stations across the UK (12 in total). However, these are fixed locations and the majority of readings are taken at a substantial height above the ground. Whilst wind profiles vary according to terrain, in all cases the elevation of a bicycle and/or bicycle component is such that wind speeds will differ from weather station readings due to the impact of the wind gradient.

The majority of the existing datasets have been determined by data collection from an instrumented bike. These bikes all use a single instrument (analogue wind vane) mounted out in front of the rider. This does provide data at a more appropriate ground elevation, however it does not take into account the airflow interaction with the bike or rider. This is particularly relevant when the item being tested is more likely to be impacted by "dirty" airflow, e.g. the rear wheel.

As we set out to develop the next generation of wheelsets, we wanted to fully understand the yaw angles that would be impacting both front and rear wheels individually, so that we could design each rim profile to perform at its best in those conditions.

Our #thinkwider rim profiles provide a new common design approach for our next generation of disc brake wheelsets. The differential front/rear profiles provide:

1. Optimum aerodynamic performance when paired with a 28mm tyre
   
2. Enhanced front wheel stability in crosswind conditions
   
3. Maximised rear wheel aerodynamics from greater rim depth
