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.

Constructed entirely from CNC machined aluminum and featuring an internal spine for maximum rigidity, the Aero Kolossos excels in both minimizing wind resistance and ensuring precise shifting. In the pursuit of marginal gains, it's crucial to avoid sacrificing your hard-earned watts whenever you change gears or encounter uneven road surfaces.

While the primary application may seem tailored to triathlons and time trials, we intentionally designed the Aero Kolossos for versatility. It performs with equal prowess in road and criterium racing, where the terrain can be demanding, and gear changes occur frequently and aggressively.

The Aero Kolossos for Sram AXS boasts a 14-tooth upper wheel and a 19-tooth lower wheel, further enhancing its performance across various cycling disciplines.
