Oversized Derailleur Cages
Ready to experience total drivetrain optimization? Introducing Kolossos, Kogel Bearing's ceramic oversized derailleur cage.
Kolossos was designed to seamlessly fit and install on your Shimano road rear derailleurs. There are many ways to describe Kolossos. Our favorite is "Mind Blown"!
Bigger IS Better
Oversized derailleur pulleys are all the rage nowadays. Big derailleur pulleys cause less deflection in the chain and slower rotations in the bearings.
Both lead to less friction and a more efficient power transfer between legs and wheels.
Kogel’s goal was to build a cage so stiff that it holds the chain like a stock cage, while offering all the benefits of low drag oversized pulleys.
Kolossos is 3x stiffer than the main competitor product and 2x stiffer compared to the original pulley cage on your derailleur.
WHY Upgrade/Replace Your Derailleur Cage
Many oversized pulley systems are plagued with vague shifting due to the lack of stiffness of the components. Plus, your stock derailleur's efficiency is limited by the size of the factory derailleur pulleys.
Kogel Oversized Derailleur Cages are:
- Built to offer low friction while maintaining shifting accuracy.
- Built for road as well as off-road use, we are not here to restrict your adventures
- Engineered with a long-tooth profile on lower pulley for better chain retention.
It's basic physics. You ride slower though sharp turns and faster though wide ones. Well, your chain flows faster around larger pulleys and slower around smaller ones. Bigger really is better...and faster!

INHERENT REAR-DERAILLEUR INEFFICIENCY
No amount of chain lube or coating can eliminate your rear derailleur's inherent design limitations. The path a chain takes during each revolution requires passing through a chicane of derailleur cage pulleys diminishing your return on each pedal stroke. It's a drag on all geared bikes and why your stock rear derailleur will never perform as efficiently as one with an oversized derailleur cage.
Now imagine riding your bike with an oversized derailleur cage, less articulation in the chain means easier spinning: maximized silky-smooth power transfer from each pedal stroke to your rear wheel. Your chain flows through the rear derailleur effortlessly, almost like a single speed, but with gears.
