Meet any challenge with the Koga Colmaro Extreme! This gravel bike combines a robust AI-optimised frame with top quality Shimano GRX components and a suspension fork. Perfect for long adventures and challenging terrain, it offers maximum comfort and traction.

The bike for rugged gravel work
While most gravel bikes have a rigid front fork, the Koga Colmaro Extreme is distinguished by a front fork with 40mm travel. This gives you just a bit more cushioning on the dirt. That puts this Koga gravel bike perfectly positioned between a road bike and a mountain bike, which start with 100mm suspension travel, and perfectly compatible with 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 Koga Colmaro Extreme's aluminium frame has been optimised using AI which ensures a perfect balance between strength, comfort and performance. The geometry is designed for stability and control on rough terrain, while the suspension fork absorbs vibrations for extra comfort. With room for tyres up to 50 mm wide, this bike offers versatility and traction.
Groupset
With the Shimano GRX 2x12 groupset, the Colmaro Extreme delivers precise shifting and a wide 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 compatible not only with challenging gravel routes but also with long bikepacking trips and very light mountain bike routes.
Finish
The Schwalbe G-One Bite 50 mm tyres provide an excellent balance between traction and rolling resistance ideal for all surfaces. This gravel bike is distinguished by the Suntour GVX32 suspension fork with 40 mm travel. This offers extra comfort on bumpy trails, allowing you to tackle just a bit more adventurous paths compared to 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 attachment points for extra luggage, perfect for adventurous bikepacking trips. The Colmaro Extreme even gives you the option of mounting a dropper post.

Didn't see the point but a suspension fork is still a nice addition.

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.
