Diederik Deelen is a well-known figure in Girona’s endurance community, both on and off the bike. As a mechanic at The Service Course for over five years, he’s become a familiar face in one of the city’s finest bike shops, helping countless riders keep their machines in top shape. But beyond the workshop, he’s also making a name for himself on the global gravel racing scene. Competing at the highest level, one of his standout achievements was finishing 3rd at the grueling Traka 360km in 2023. Whether in the workshop or on the racecourse, Diederik is a true pillar of the Girona cycling scene.
