Although tested as the second bike, it quickly became clear: this is one, if not the all-rounder. Despite its compact shape and small 27.5-inch wheels, the frame is quite long, but this is well compensated for by the handlebars that curve back from the stem to the brakes. If you grip the handlebars there, you can sit comfortably for hours; if you go to the brake levers, you'll find yourself in positions like the Riverside, with full control of the bike on the lower handlebars.
With seven fixed points for luggage ready for all tours, the cool mix of parts was given a sporty double crank. The tyres are also a top choice, with the "bald heads" the bike rolls excellently on firm paths despite the weight, the knobs on the sides ensure cornering is safe, of course only on moderate terrain, the thick tyres also provide a lot of comfort, just like the good-natured aluminium frame and the seat post. The quick release there is ingenious! Adjust the seat height for the car, off-road, downhill or in jeans, top. Balanced riding behaviour, only fast acceleration and rough terrain are not mastered by the Koga.
Conclusion on the Koga Colmaro Extreme
A model representative of the gravel bike genre, no island talents, but also no real weaknesses. Four bikes in one for the price is really sensational!
