Chapter2 KOKO Aero Frameset
The Chapter2 KOKO aero frameset is CHAPTER2’s top-tier aero road chassis: Kamm-Tail tube profiles, fully integrated cabling, and a serviceable T47 (86.5) BB create a fast, stiff platform that still rides smooth. Adjustable compliance via a dual-position seatclamp, up to 32 mm tire clearance, and vibration-damping stays/post deliver real-world speed on imperfect roads. Mechanical and electronic compatible, UCI-approved.
