The Doppler offers riders a traditional touring bike with smooth-rolling 650b tires that can venture into the dirt. 650b wheels offer a distinct advantage by offering a larger-volume tire that provides a comfortable and quick ride on pavement with greater cushion and traction on rough roads and unpaved surfaces. Ideal for loaded touring and harsh conditions, the Doppler frame offers classic road-bike geometry and a high level of functionality.
