Swiss Side Wind Tunnel Days – setup optimization by Swiss Side in the wind tunnel

A complete wind tunnel aero-optimisation, like that done for Swiss Side professional athletes such as Andy Raelert. This dream came true for Markus Ganser (44 from Stolberg, Germany) and Finn Borg (60 from Wädenswil, Switzerland). Markus and Finn treated themselves to a day in the wind tunnel with Swiss Side in Immenstaad, with the goal of making their bike setup more aerodynamic and therefore faster. Both of these age group athletes have competed several times at the Ironman World Championships in Hawaii and were interested in learning more about the benefits of aerodynamics in the cycling world. Their goal was clear, to benefit Swiss Side’s unique Formula 1 experience and methods to save them valuable minutes in their next races. During their wind tunnel, various riding positions were evaluated as well as different equipment such as aero wheels, hydration systems, race suits and helmets. At the end of the day, Swiss Side was able to make significant aerodynamic improvements on both riders, with drag reductions over 20 watts each. Finn is the new Swiss Side record holder for the total amount of power saved. With the new changes made to Finn’s setup, Swiss Side was able to reduce his drag by 30 watts, which translates to an improvement of 10 minutes in his long distance races.
We are excited to have been able to make significant improvements for each Markus and Finn to give them an additional competitive edge in their upcoming races.

Julia Gajer with Swiss Side in the Wind Tunnel

Swiss Side recently spent a day in the wind tunnel with newly signed pro-triathlete Julia Gajer. The entire team’s goal was clear – harvest watts! Once again, the aerodynamics team delivered, finding solid gains in reducing drag, to save Julia time and energy out on the bike.
A wide range of testing was done, including optimisation on the bike itself with evaluation of wheel setups, drinks & food storage, as well as extensive analysis of various position setups on the bike, in addition to race suits and helmets.
At the end of the day, Swiss Side’s engineers were able to confirm one of lowest ever drag levels they have ever measured in the wind tunnel.

Michael Raelert takes his turn in the wind tunnel with Swiss Side


Following Swiss Side’s huge successes in reducing aero drag and making significant time savings with older brother Andreas, it was Michael Raelert’s turn to step into the wind tunnel. Andreas and Michael now share the same aerodynamically optimised Cube Aerium time trial bike, developed by Swiss Side for the 2015 Ironman World Championships in Hawaii, so it was time to work on Michaels complete setup to help him extract the maximum potential from his bike setup. The Swiss Side aerodynamicists were already very familiar with the interaction between rider and bike having completed extensive CFD work developing the frame. So it was a matter of confirming these trends with Michael and fine tuning his body position and equipment setup to find the optimum. Once again, significant time savings were achieved in particular with a modified body position, race suit and helmet.

Following the wind tunnel session, Michael was sent out on the road with Swiss Side’s unique instrumented bike, in order to collect real world aero data for correlation with his wind tunnel measurements and for use in performance simulation calculations.

The whole Swiss Side team wishes Michael the very best for his season ahead!

Swiss Pro Mathias Hecht in the Wind Tunnel with Swiss Side

Mathias Hecht has made some changes for his 2016 season, switching bikes from the Trek Speed Concept to the new Canyon Speedmax CF SLX. With this change, the Swiss Side aero team wanted to ensure that the new bike was better and that his setup was maximized for the absolute best possible performance. The entire team had to battle with very cold testing temperatures, between 2 – 6C, so the testing was divided into blocks: 1. Bike compare without rider; 2. Bike compare with rider (with warm clothes); 3. Rider position optimization (with warm clothes); 4. Final position and helmet optimization in race clothing.

Despite the challenging conditions, significant gains were found. The Canyon bike confirmed to be an improvement of 3W over the Trek. With the rider themselves contributing around 75% of the total drag on the bike, as expected, position optimization delivered the biggest performance gains. Improvements of just over 20W were achieved. On Mathias, the Louis Garneau P-09 aero helmet was 4W better than the Bontrager Aeolus helmet. However it is important to note that from our wind tunnel testing experience, the helmet performance is often dependent on the rider’s body shape and position. And for those who are interested, the difference between Mathias’ race suit and his warm clothing was 21W!
Mathias’ main season goal for 2016 is to challenge for the win at Ironman Switzerland on 24th July.

Andreas Raelert kicked off his season with a solid podium on a tough course at the Cannes International Triathlon last Sunday. Andy was riding the new HADRON Ultimate 800+ aero wheels and the Swiss Side co-developed Cube Kona bike.
Andy was able to confirm his good training preparation in Cannes, placing third place behind the strong Frenchman Etienne Diemunsch and defending champion Giulio Molinari from Italy. Andy had a total time of 3:31:52 hours after the 2km swim course, a very challenging 80km bike course with the concluding 16km run. He crossed the finish line after a thrilling race just behind Etienne Diemunsch, who won the race in 3:30:08 hours, and Molinari, 3:30:37 hours.
«My first race of the year has been a very demanding competition», said Andreas Raelert after his finish. «I am very satisfied with this first real hard test under race conditions.»

Following comprehensive prototype wheel testing both in test rigs as well as out on the road, the final production specification HADRON Ultimate full carbon wheels were pushed to their limits during recent brake dyno testing. The results did not disappoint!

The brake testing dyno.

The HADRON Ultimate 485 in wet testing simulations.

There were two primary targets for the brake dyno testing:
1. To test the braking performance of the rims and their special high-temperature, high heat rejection carbon laminate used on the HADRON Ultimate braking surface. Tests were done in both dry and wet simulated conditions.
2. To perform extreme braking tests to ensure the resistance and stability of the carbon laminate well beyond the normal operating window, under the more than double the normal maximum braking loads ever seen on a wheel.

1. Brake performance testing

The brake performance of the rims proved excellent and comparable with the best carbon rims on the market. ISO standard testing was completed in both dry and wet conditions. This involved repeated braking events at increasing braking loads to evaluate the rim performance with building heat as load increases.
In dry conditions the wheels showed excellent performance without fading in the normal braking load range. Fading only appeared under extreme braking loads, above 90N force on the brake lever, which is above the loads a normal rider applies (typically maximum 70N). The braking performance showed to be superior to aluminium rims by approximately 14% in terms of maximum braking power.
In wet conditions the wheels performed well for carbon rims, again without any drop-off in braking performance in the normal braking load range, with brake lever force up to 70N. Note that in wet conditions, riders tend to use significantly lower force on the lever than this. Comparing with aluminium rims, the braking power in the wet for the same brake lever force is reduced by approximately 30% (compared to the dry). This is typical of all carbon rims regardless of the brand. Important to note nonetheless is that there is still sufficient braking power to provide maximum useable braking and to lock the wheels. The lower effective braking power (for the same brake lever force) in wet conditions is the braking compromise of carbon rims to aluminium rims.

Typical brake performance result graph.

2. Extreme brake testing

Extreme brake testing simulations were performed which represented more than double the braking load a wheel would even see in an extreme braking event with a heavier (100kg) rider. The target in this test is to pass three sequences of the extreme simulation without visible or measurable degradation on the rim. Not only did the rims pass three sequences, testing was continued and after five sequences, still no damage was observed and the testing was concluded. Big success!


The overall the braking performance and safety of the HADRON Ultimate wheels proved to be at the absolute highest level. The correlation to road testing and subjective rider feedback has been excellent. With this final step, the HADRON Ultimate production specification wheels have passed the final certification step.
