Ball Kolossos Derailleur Cage Oversized Dura-Ace 9200 - Gr

Big derailleur wheels are not the last step to free speed.
The Kolossos is now available in an Aero version, so your wheels and chain are protected against the wind, for riders looking for maximum aerodynamics.
The Aero Kolossos is built with Kogel ceramic bearings.
Made entirely from CNC machined aluminum with an internal backbone for maximum stiffness, the Aero Kolossos helps you cut through the wind and maintain shifting accuracy.
When it comes to marginal gains, there's simply no point in gaining a few watts only to give away your advantage every time you change gears or hit rough asphalt.
While the obvious use is for triathlons and time trials, we didn't want to limit the range of use of these cages.
The Aero Kolossos is equally at home in road races and criteriums, where the terrain can be bumpy and frequent and aggressive shifting is required.

- Aerodynamic shape for maximum time savings
