Based on research and development that went into the Fast Bird mountain bike tire with the help of Thomas Frischknecht, the Small Bird features a dual compound tread designed with low and firm knobs in the center and softer higher knobs on the sides for railing corners. Since it was introduced, it has become a favorite for American courses. JP says: Grip it and rip it with this tire. It will do things you did not think possible!
Also offered in a 36 mm size for Gravel applications.
Offered in two (2) casing options: traditional Cotton Casing for the smoothest and most supple ride, and Flying Doctor Casing, which is slightly stiffer, more durable, and about 10 grams lighter. Flying Doctor allows lower pressure without having the feeling that the tire will roll or collapse in the corners.
Both casing options include the Dugast Neoprene sidewall treatment, which means you don't have to seal the sidewalls with Aquasure.
