Is the system safe? Since 2012, when TREK first installed IsoSpeed on the Domane, the system has been tested and won every major professional endurance race at Strade Bianche, Ronde van Vlaanderen and Paris-Roubaix. Today, the IsoSpeed system is not only available on road bikes such as the Domane, Madone, but also on the Boone cross bike, Procaliber mountain bike, Checkpoint gravel bike and even the FX everyday fitness bike.
