Kogel Kolossos SRAM eTap AXS Road Seal Oversized Pulley Cage
This Kogel Kolossus oversized pulley cage is an upgrade for SRAM eTap AXS 12-speed road bike rear derailleurs and features durable ceramic bearings with minimal contact "Road" seals to dramatically improve drivetrain efficiency. Easy to install straight out of the box, it features 14-tooth upper and 19-tooth lower pulley wheels that lower watt-sapping friction by reducing chain articulation.
The pulleys are held within a super-stiff cage that enhances the smoothness and accuracy of rear gear shifts. The cage features an inbuilt chain catcher, and this combines with the long tooth profile of the lower pulley to stabilise the chain and prevent it from jamming.
