Kogel Kolossos Oversized Derailleur Cage For Shimano R7100

The Kogel Kolossos Oversized Derailleur Cage is designed to enhance drivetrain performance by significantly reducing friction. Tailored specifically for Shimano R7100 series derailleurs, this upgrade brings elite-level efficiency to competitive road and gravel riders.

Engineered With Ceramic Precision: Kolossos pulleys are built with ceramic balls and hardened steel races, ensuring ultra-low rolling resistance and long-term durability. The oversized design allows for reduced chain articulation, resulting in smoother, quieter pedaling and improved power transfer.

Superior Shift Performance: CNC-machined alloy cage arms deliver uncompromising stiffness to maintain precise shifting under load. The increased rigidity reduces flex and ensures consistent shifting even during aggressive sprints or climbs, providing a reliable edge in all conditions.

Optimized Chain Control: The long-tooth profile of the lower pulley enhances chain retention, keeping the drivetrain secure over rough surfaces. A built-in chain catcher prevents derailments and jams, giving riders added confidence on both tarmac and trails.

From the high-speed demands of road racing to the unpredictable terrain of gravel riding, the Kolossos derailleur cage is built to handle it all. With no restrictions on where you ride, this is the ultimate performance upgrade for riders seeking every possible advantage.
