27,2 MM SEAT POST
Seat post with a diameter of 27.2 mm with excellent shock absorption.
The cables run through the frame tubes and are therefore better protected from the influences of the weather. Moreover, the bike is easier to keep clean and has an improved, leaner appearance.
Many KOGA models are equipped with disc brakes. Disc brakes provide a stable braking performance in all weather conditions.
TAPERED HEAD TUBE
Tapered ball head tube. The lower ball head tube has a larger diameter than the upper one. The larger diameter enables the possibility of a more rigid construction without adding weight, resulting in greater steering stability.
