Big pulley wheels were not the final step to free speed. Kolossos now comes in Aero, shielding your wheels and chain from the wind for those riders looking for maximum output. Aero Kolossos is built with Kogel ceramic bearings and road seals.
Crafted entirely from CNC machined aluminium with an integrated internal spine, the Aero Kolossos is designed to offer both superior aerodynamics and unwavering shifting precision. In the pursuit of marginal gains, it's essential to ensure that the hard-earned watts you save aren't lost every time you change gears or encounter rough road surfaces.
Although the primary application may seem tailored for triathlons and time trials, we intentionally designed the Aero Kolossos to be versatile. It thrives just as effectively in the dynamic world of road and criterium racing, where uneven terrain and rapid, aggressive shifts are par for the course.
The Aero Kolossos for Shimano features a 12-tooth upper wheel and a 19-tooth lower wheel, enhancing its performance across various cycling disciplines.
