Kolossos ST Oversized Derailleur Cage - SRAM XPLR eTap AXS

Upgrade your SRAM XPLR gravel drivetrain with Kogel's oversized derailleur cage. Designed specifically for the XPLR groupset—bridging the gap between road and mountain cassettes—the Kolossos ST features our shortest cage ever with an offset upper pulley to optimize gear range without the extreme offset of our Eagle version.

Equipped with high-quality stainless steel bearings, the Kolossos ST delivers excellent durability and smooth performance at a more accessible price point. Built stiffer than stock and made of aluminum so you can bend it back into shape after rock strikes.

Ships with low-friction road seals for maximum efficiency. Bearings can easily be rebuilt with cross seals for wet, muddy conditions. Built for shifting accuracy, gravel-worthiness, and chain retention.

Fitment: Compatible with SRAM Red XPLR eTap AXS, Force XPLR eTap AXS, and Rival XPLR eTap AXS rear derailleurs.
