The ultimate in premium components for the most discerning cyclists
A special collaboration between Mighty Velo and Joseph Kuosac, the JK11 Ace features a carbon wheelset that enhances its acceleration, responsiveness, and overall speed. It also makes use of the highest quality components available, such as the advanced Shimano Dura-Ace derailleur, Ergon SMC Gel Saddle, and Ergon GP2-L grips. These components allow it to attain the pinnacle of performance and comfort, with top-of-the-line gear shifting and braking, while not sacrificing portability.
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 Dura-Ace Groupset
The Shimano Dura-Ace is the pinnacle of road cycling performance. Renowned for its precision, efficiency, and reliability, this top-tier groupset delivers unrivaled shifting and braking performance, even under heavy load or in challenging conditions. With advanced technologies, lightweight construction, and exceptional durability, the Dura-Ace is the choice of professional riders seeking the ultimate cycling experience.
Juin-Tech Cable Actuated Hydraulic Disc Brake
The Juin-Tech hydraulic disc brakes provide smooth and responsive braking thanks to non-corrosive and high-stability mineral oil within. They are also easy to adjust to the right state, resulting in more durable rotor and disc pads. Enjoy the greatest braking power on the road.
