The ultimate long-distance road bike where comfort and speed are paramount.
— What is it?

Designed and tested in Europe’s toughest ultra-race.

We know a thing or two about making a good Endurance bike, hell, we even road tested the Durmitor in the Transcontinental - Europe’s greatest ultra-endurance race! With the race under our belt we came back and dialed the design up to eleven.

Endurance and speed take the front seat here, mixing fast handling with a stable wheelbase for a lively ride. Disc equipped for reliable braking in all conditions, with wide clearances for those sweet-rolling larger tyres, the Durmitor, like you, will go far.

We built this bike to go far, fast.
— why we made it?

Built to match your Endurance

Careful attention has been spent in every aspect of the design to make the ultimate long-distance road bike. Compact geometry increases seatpost compliance soaking up more road buzz. At the same time the shortened frame tubes maintain stiffness in the drivetrain. Skinny seat-stays ensure that the frame’s rear end is a little softer while the ability to fit 32c tyres brings all the benefits of larger tyre volumes.

From ultra-racers to all-day mile munchers, this bike is built to match your endurance.

Endurance Race Geometry

Using our extensive fitting experience based on repeated analysis and observation of rider positions we developed the Endurance Race geometry to enhance rider comfort and increase stable handling while maintaining classic race credentials. Stack height is kept suitably low for a balanced position without sacrificing the ability to ride all day long.
