Recap of Ironman World Championships Kona, Hawaii

Our Kona week started with the successful launch of Andreas Raelert’s new CUBE bike, which was the result of the two year collaboration between Aerodynamics by Swiss Side, CUBE and Andreas Raelert. International triathlon media and public were fascinated by the breakthrough technology and the new aerodynamic features on Raelert’s new bike.

We enjoyed feeling the excitement for the World Championship race increase every day and met up with our Swiss Side athletes, that took advantage of the free Kona Aero Support Package, for a beautiful sunset dinner at the beach.
The day of the race we got up at 4am and made our way down to the start of the legendary Ironman World Championship race with hundreds of other Ironman fans and supporters. The excitement was immense, when the race finally started with Swiss Side sponsored athletes Andreas Raelert and Julia Gajer in the pro categories, as well as dozens of age-groupers with Swiss Side HADRON aero wheels.
Andreas Raelert made it out of the water as part of the top group. On the first 50 kilometers of the bike course, Andreas Raelert maintained in the lead group before a 5 minute penalty turned his race upside down. Despite the handicap, he tried to keep his rhythm on the bike and maintain the gap to the front. However, Andreas Raelert felt the pre-race issues with his left thigh coming up very early in the race. He finished the 180km bike course in 4:46:07 hours and started into the marathon. Unfortunately after eight kilometers of the run, the muscular issues in his left thigh proved to be quite serious and he had no choice but to prematurely end the Ironman Hawaii.
Julia Gajer had a good start and finished the swim in fourth position. However on the bike, her energy levels simply weren’t there on race day and she fell back in the field. After the transition to the run, she took the painful decision to retired from the race.
In the age group categories, 10 out of the 11 Kona Aero Support Package athletes crossed the finish line as Kona Ironman, amongst which were some absolute top level placings. It was an incredible hot and long day out on the lava flows of Kailua-Kona for every single athlete as well as all of the supporters out there. Congratulations to the winners Jan Frodeno and Daniela Ryf, as well as to all of the other athletes, fans, supporters and the organizers for another memorable Ironman World Championships!

Cycling & Aerodynamics Leaders Join Forces To Develop World’s Fastest Triathlon Time Trial Bike

Collaborators CUBE, a leader in bike manufacturing, and Swiss Side aerodynamic experts, have formed an official partnership. By combining their respective areas of expertise, the two brands have pursued a goal to develop the fastest triathlon time trial bike in the world. This bike has the most aerodynamic carbon frame ever creating forward motion in its purest form.

CUBE and Swiss Side teamed up for the first time in 2015 and the results were phenomenal. The CUBE Aerium C:68 high-end triathlon bike was modified and adapted in the wind tunnel in Immenstaad on Lake Constance by CUBE and Swiss Side as part of the joint Raelert Brothers’ sponsorship. Runner-up World Champion, Andy Raelert rode this “ultimate aero bike” to an impressive second place finish at the 2015 Ironman World Championships in Kona, Hawaii.
The CUBE Aerium C:68 was put through a battery of wind tunnel testing by Swiss Side’s expert aerodynamics team and modified for best possible performance. The bike was then equipped with Swiss Side HADRON Ultimate 800+ aero wheels and ultimately saved Raelert 10 plus minutes over the 180 km bike course. The new CUBE Aerium C:68 is now available to the public which makes it possible for all triathletes to benefit from ‘Aerodynamics by Swiss Side’.
This year, the engineers at CUBE are, once again, working together with the aerodynamics experts at Swiss Side to create a world-class bike for the 2016 Ironman World Championships in Kona, Hawaii. Raelert’s new prototype bike will allow extra valuable minutes to be shaved off the bike course time thanks to the optimisation of the entire rider-bike system. With over 50 years of Formula 1 experience, Swiss Side’s engineering team is number one in aerodynamics, bringing the latest technologies to cycling research and development. Raelert’s new triathlon time trial bike was developed with development methods used in Formula 1, including analyses computational fluid dynamics (CFD), wind tunnel testing, performance simulations and measurements with the unique Instrumented Bike.

“CUBE is a big name in the cycling industry and the right partner to put our Formula 1 expertise to constructive use,” says Jean-Paul Ballard, Swiss Side’s technical director. “This partnership guarantees the development of a triathlon bike that will set new standards in the bike industry.”
The CUBE development team are also convinced that the prototype will set a new benchmark for the triathlon segment,” says Bernd Schenkl, Head of Engineering at CUBE. “Our goal is to build the fastest triathlon bike in the world. The current prototype is the product of a two-year development phase, during which, we worked closely with Swiss Side to create a world-class aero bike for Andy Raelert. Our focus was on combining uncompromising aerodynamics with a unique design to build a bike that is not only the fastest in wind tunnel tests, but one that also delivers outstanding maneuverability and plenty of set-up options to allow athletes to find the perfect riding position. This approach is crucial to ensuring maximum on-road performance. The innovative C:68 carbon frameset transforms every watt of energy expended at the pedals into speed and perfectly combines a lightweight structure with extraordinarily high stiffness and ultimate aerodynamics.”
The Raelert brother’s new CUBE racing machines proudly carry the ‘Aerodynamics by Swiss Side’ logo. The bike setup is equipped with Swiss Side HADRON Ultimate 800+ aero wheel, independently confirmed to be one of the world’s best aerodynamic wheelsets. Swiss Side wheels are naturally also developed with the same outstanding methods directly from Formula 1 aerodynamics.

Eurobike Wind Tunnel Battle Recap:

For the 3rd year in a row, Swiss Side hosted its annual wind tunnel battle event at the GST wind tunnel in Immendtaad, Germany, just a few minutes from the Eurobike show. The week began with a 12hour marathon wind tunnel session with Andreas Raelert, finalizing his setup for the Ironman World Championships in Kona, Hawaii on 8th October. The following days saw Swiss Side hosting the leading European and International press, where each group was invited to measure anything they wanted in the wind tunnel, thereby taking advantage of the Swiss Side team’s unmatched aerodynamic know-how. There were some very eye opening testing done, including naturally battles between Swiss Side aero wheels and their competitors (no surprises here) but also lots of equipment testing such as helmets, jerseys, drinks systems, as well as riding positions analysis. The most surprising results were that loose straps on the helmet can cost you around 4.5W! Also the difference between riding a road bike holding onto the centre of the handle bars, compared to being in a low aero position on the lower drops, is just over 100W difference in aero drag!

Andreas Raelert sets bike course record in Copenhagen


Seventh place in his comeback race in Denmark – Rostockian leads the Ironman Copenhagen for long and validates his Kona slot – Focus is on Hawaii now
Rostock. Andreas Raelert made his way back into racing with a good performance at the KMD Ironman Copenhagen. After being one of the main protagonists of the race, the Rostockian eventually finished after 8:29:39 hours in seventh place. Swedish Patrik Nilsson celebrated an impressive win in 7:49:18 hours ahead of British Will Clarke (7:59:31 hours) and Brazilian Fabio Carvalho, who finished the race in 8:07:10 hours. “Overall, I can be satisfied with my first race after I had a long break from competition”, Andreas Raelert said after the race in the Danish capital, “especially the swim and the bike felt really good today.”
In the Amager Beach Park, Andreas Raelert already had a good start into the race on the 3.8 kilometer long swim course. He reached the first transition zone in 47:42 minutes, only the Brazilian Igor Amorelli was quicker in 47:38 minutes. “My swim was good,” Andreas Raelert said, “but I needed some more time in transition.” After having solved small issues with his helmet visor, the Rostockian embarked onto a strong bike leg. After about 50 kilometers, he took the lead and became one of the main pacers of the race. In 4:13:57 hours, Andreas Raelert finally set a bike course record although he had to stop for a short restroom break at kilometer 130. “On the bike, it went really well,” Andreas Raelert said, “the atmosphere was great and the course was good. This has been really fun.” After a race time of 5:04:19 hours, Andreas Raelert reached transition three seconds ahead of Swedish Patrik Nilsson, the Brazilian Fabio Carvalho followed almost a minute later in third place.
Andreas Raelert started into the marathon in third place after another restroom stop due to some persistent stomach problems. “The pace was good until the half marathon mark,” he said later. Andreas Raelert moved into runner-up position quickly, and he started making up time on the leader Patrik Nilsson. In about 1:22 hours, Andreas Raelert ran the first half marathon being in second place.
On the second half of the marathon, Andreas Raelert then had to pay tribute to missing training kilometers in recent weeks. He crossed the finish line in 8:29:39 hours. “Of course, a victory would feel much better,” Andreas Raelert said, “but I’m still on the way back. For me it is important to be in race shape on October 8 in Hawaii and to make my way in training in the next few weeks. Today’s signs give me a lot of optimism. Today, Patrik Nilsson had a great race, it was really impressive.” The Rostockian was impressed by the Danish audience, too: “The people were amazing, the atmosphere was just great.” Andreas Raelert wants to make his way to Kona now based on this first competition after his long break due to his injury.
