The K2 Mod 4.0 is known for its lightweight design and composite build. It features hybrid construction combining an aluminum frame with carbon fiber components to balance stiffness and ride quality. A joy to ride, this is a fast and comfortable bike, ideal for a casual enthusiast between 5'11" and 6'3". Excellent condition, a few normal-course scratches, well maintained, never laid over.

Main Triangle (Aluminum)

Provides the frame with excellent stiffness for efficient power transfer and acceleration.

Fork & Seat Stays (Carbon Fiber)

Carbon in these areas to dampen road vibrations and save weight, smoothing out the harshness sometimes found in pure aluminum frames.

Premium upgraded cockpit featuring Cinelli stem, 3ttt Forma SL Due bars ($70-$100 on eBay), Cane Creek carbon headset
