Daniela Ryf, DT Swiss "Aerodynamics by Swiss Side" athlete, will be racing at the Ironman 70.3. Rapperswil this weekend. A couple weeks ago, Daniela Ryf was in the wind tunnel with Swiss Side's aerodynamic experts to fine tune her setup. This was Daniela Ryf's first time to the wind tunnel. She was positively surprised on how acurately you can measure the aerodynamic impact on certain changes in the setup. Daniela Ryf said: "This is a great way to fine tune the results from the latest track test. It is very valuable for me to know the impact of choices on different size aero wheels, bottles, helmets and head positions."
