Thomas Glättli is the driving force behind Vélobsessive. As an enthusiastic cyclist and dedicated amateur athlete, he was tired of compromising when it came to finding the perfect road bike. In 2019, he founded Vélobsessive with a clear goal: the rider shouldn't have to fit the bike; the bike should fit the rider.
