Eker Stark Frameset
A swift, strong and elegant cross-country mountain bike.

The bike that started it all

Eker Stark is a cross-country mountain bike that is swift, strong and elegant. The frame is made by hand, all the way from harvesting the tubes to preparing and joining them into unique pieces of art which nevertheless can withstand extremely tough riding in all types of conditions.

Eker Stark Frameset

It has taken us nearly four years to develop Eker Stark. We have finally achieved the best balance between strength and flexibility in our frames, with our own custom made in Sweden dropouts, head tube, bottom bracket shell and seat post insert, in black anodised aluminium. The design, high quality finish and details gives you a bike that is a jewel to your collection.

All Eker Stark sizes are built around the 622 mm wheel size (also known as 29”) to allow you to scale those obstacles faster and safer than with smaller wheels.
