Birdy JK11 Road | 11-Speed | Performance Foldable Bike
A special collaboration between Mighty Velo and Joseph Kuosac, the JK11 Road features a carbon wheelset that enhances its acceleration, responsiveness, and overall speed while providing a smooth, comfortable ride. With reduced weight, improved aerodynamics, and top-notch components, the JK11 Road gives you the speed and agility of a road bike in one compact foldable package.
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.
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.
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.
