The public launch of the first ‘Linkin Trail’ model will be held at Solothurn’s Bike Days bicycle festival from May 8th to 10th 2015 in Swizerland.

Frame integrated

With its system integrated ‘Internal Suspension Technology’ kinematics, abbreviated as IST, the rear shock has been entirely built into the frame, driven by a set of links. As one of the first companies worldwide the start-up is also early with another concept, as the frame has been built to fit both 29-inch wheels and the new 27.5 Plus size tyres.

Invisible shock damper

With Bold Cycling Ltd. the Swiss bicycle industry spawns a promising newcomer. The invisible shock damper offers a full 130mm (5 inches) of travel built neatly into the seat tube. Not visible from the outside, the shock is driven by a patent-pending set of links. Thanks to IST technology the frame does not just serve as a structural element but also as a tough skin to protect the shock from weather, loose rocks and dirt.

Additional advantages.

Apart from the clean looks and aesthetics, integrating the entire suspension into the frame has some additional advantages. With the frame’s kinematics new links positioning is possible adding both to the stiffness and to a suspension platform that is fully active under drivetrain and braking forces. As the rear shock is not connected to the frame’s top tube either, every frame size can be designed to meet the exact needs. This means that even a small frame fits a full-size water bottle while offering a low-slung top tube and heaps of standover clearance. The low centre of gravity resulting from the compact, stiff linkages of the rear suspension further add to the solid handling characteristics.

DT Swiss stepped in as technology partner

Convinced by the IST kinematics and the related concept, DT Swiss has stepped in as technology partner and has built a shock that has been taylor-made for the needs of Bold with the DT Swiss X313 customized.

Bold Cycles Ltd is based in Lengnau, close to Biel, and has been founded in 2014 by Vincenz Droux and Robert Droux. Vincenz Droux is well known within the bicycle industry as the owner of Flow AG. He has been involved in the development of products and brand images for a number of international and national bicycle manufacturers.
