Take any challenge with the Koga Colmaro Extreme gravel bike! With a robust AI-optimised frame and top quality Shimano GRX components as well as a suspension fork, it is perfect for long cycling adventures and challenging terrain. The Colmaro Extreme offers maximum comfort and grip, and with clearance to accommodate wide tyres and with several luggage options, it is an ideal bike for explorers keen to brave the unknown.
An excellent choice for rugged gravel riding
While most gravel bikes have a rigid front fork, the Koga Colmaro Extreme distinguishes itself with a suspension fork with 40 mm travel. As this gives you more cushioning when riding off-road, this Koga gravel bike positions itself perfectly between a road bike and a mountain bike (which start with 100 mm suspension travel), and is perfectly suitable for both single tracks and gravel. Are you hesitating between buying an MTB and a gravel bike? Then this Koga Colmaro Extreme is the answer to all your questions!

Frame
The aluminium frame of the Koga Colmaro Extreme has been optimised using AI to ensure a perfect balance between strength, comfort and performance. The geometry is designed with a focus on stability and control on rough terrain, and the suspension fork absorbs vibrations for extra comfort. With clearance for tyre widths up to 50 mm, this gravel bike offers versatility and traction.
Groupset
With the Shimano GRX 2x12 groupset, the Colmaro Extreme gravel bike delivers precise gear shifting and a wide gear range. The hydraulic disc brakes perform superbly in all weather conditions, giving you confidence in your stopping power at all times. This makes the bike suitable not only for challenging gravel routes but also for long bikepacking trips and very light MTB routes.
Finish
The Schwalbe G-One Bite 50 mm tyres provide an excellent balance between grip and rolling resistance, ideal for all surfaces. The Colmaro Extreme gravel bike distinguishes itself with the Suntour GVX32 suspension fork with 40 mm travel, which gives you extra comfort on bumpy trails and, therefore, the courage to tackle more adventurous routes than you would on a regular gravel bike. For even more comfort, the seat tube is designed to have some flex; ideal for bumpy terrain. In addition, the frame features luggage attachment points, perfect for adventurous bikepacking trips, and is even dropper post ready.

Didn't see the point but a suspension fork is still a nice addition.
- Christ 3 May 2025
What a fine bike and great for taking on a rougher stretch. Sturdy enough to pull a trolley, attach a carrier, take along a tent and enjoy.
