Specially customised for adventurous riders

A special collaboration between Mighty Velo and Joseph Kuosac, the JK11 Gravel features a 18” carbon wheelset with inherent damping properties to absorb bumps and vibrations, providing a smoother and more comfortable ride. Its Brooks C17 carved, waterproof saddle and Brooks cambium rubber grips are made for comfort under all conditions, while its Shimano Ultegra 11-speed derailleur allows the bike to overcome uneven surfaces and climb smoothly. The JK11 Gravel is a versatile bike designed to tackle adventures over almost any terrain.

Joseph Kuosac Wheelset with Billy Bonkers Tyres

The Joseph Kuosac C38C carbon wheelset uses far lighter material than aluminium, with increased lateral and radial stiffness and improved aerodynamics. This results in a noticeable improvement in responsiveness and acceleration. For the JK11 Gravel, this wheelset has been paired up with Billy Bonkers tyres with closely positioned blocks for grip on dusty and sandy ground, equipping it for uneven terrains and leisurely rides over gravel.

Shimano Ultegra Groupset

The Ultegra R8000 series features a low profile and single tension construction. It does not hit the chainstay even in rough riding conditions, providing smooth and silent performance. The shifter offers clear contact with balanced rigidity, weight, and stopping power, while stabilizers between axles reduce deformation and improve braking efficiency.

Juin-Tech Cable Actuated Hydraulic Disc Brake

The R1 brake system mimics the powerful performance of traditional hydraulic brakes, but its cable-actuated design makes it a more versatile choice for those who prefer a variety of control options.
