KOGEL KOLOSSOS Oversized Pulley Cage SRAM eTap AXS Red & Force

Upgrade your drivetrains performance with the Kogel Kolossos Oversized Derailleur Cage, engineered specifically for use with SRAM Red and Force eTap AXS 12-speed rear derailleurs. This high-precision pulley system replaces the stock 12-tooth pulleys with a 14-tooth upper and a 19-tooth lower pulley, delivering reduced chain friction, greater drivetrain efficiency and remarkably smooth shifting.

Key Features:

• Fully compatible with SRAM Red & Force eTap AXS 12-speed road derailleurs (including the A2 version of 11-speed Red eTap).

• Oversized pulley configuration (14T upper / 19T lower) offers smoother chain path and less deflection for increased power transfer.

• CNC-machined aluminium cage for high stiffness (claimed 3 main competitor & 2 stock) and optimal shifting accuracy.

• Improved chain retention via long-tooth lower pulley and integrated chain catcherdesigned for road and mixed-terrain performance.

• Available with durable stainless-steel bearings (Kolossos ST version) or premium ceramic bearings for ultra-low friction upgrades.

Why Youll Appreciate It:
When you invest in a high-end drivetrain, every watt counts. The Kolossos cage helps ensure that more of your power makes it to the wheel with fewer losses, smoother transitions and improved stability over shifting. Its a smart upgrade for riders chasing performance margins, refined feel and drivetrain longevity.

Fit & Installation Tips:

• Compatible only with SRAM Red and Force eTap AXS 12-speed rear derailleurs (not Rival)verify your setup before ordering.

• Because of the larger pulley sizes, you may need to install a slightly longer chain and re-check your B-screw, limit screws and derailleur hanger alignment.

• Use Loctite 242 (provided) on mounting bolts and periodically inspect cage alignmentskewed fit can reduce shifting precision.

Fit Note:
Ensure your frames rear derailleur clearance accommodates the slightly longer cage length. While designed for road and some gravel use, check ground and tyre clearance especially if using compact frames or big tyre setups.
