Specially customised for riding long and fast on the road

A special collaboration between Mighty Velo and Joseph Kuosac, the JK11 Dropbar not only features a carbon wheelset that enhances its acceleration, responsiveness, and overall speed, but also a dropbar which allows cyclists to maintain high speed over long distances thanks to the multiple hand positions and more aerodynamic riding posture it offers. Every aspect of the JK11 Dropbar is designed to achieve the optimal combination of performance, weight, and quality.

Joseph Kuosac C38C Wheelset

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. Whether you’re out the saddle on a climb, attacking a descent or sprinting for the line, carbon road wheels give a sharp, responsive feel.

Shimano Ultegra Groupset

Stress-free operation is an essential trait for road bike components. The Ultegra R8000 series delivers in this regard, with 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.

PRO LT Compact Dropbar

The faster and longer you cycle, the more aerodynamics come into play. Dropbars allow you to assume riding postures that reduce drag and increase speed and efficiency. The PRO LT Compact Handlebar aids your comfort and control by boasting drops with a compact bend. You can easily shift from the top or hoods to the drops, or vice versa. The brake and shifter levers are also easier to reach as a result.
