Ready to experience total drivetrain optimization? Introducing Kolossos, Kogel Bearing's ceramic oversized derailleur cage.Â
Kolossos was designed to seamlessly fit and install on your SRAM and Shimano road rear derailleurs. There are many ways to describe Kolossos. Our favorite is "Mind Blown"!
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.
Kolossal Performance
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.Â
Kolossos is 3x stiffer than the main competitor product and 2x stiffer compared to the original pulley cage on your derailleur.
Make It Uniquely Yours
Take your bike's personalization to the next level with a custom-configured Kolossos. Choose anodized color combinations that best match your riding style. There's no reason to limit your imagination so go big!
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!
I’m very satisfied with Kogel products. There is less friction because of it and that’s making me faster and always aiming to the top places at the races. Since I’m using Kogel products I can feel the difference, especially at the beginning whenI compare other products to Kogel one’s. I’m pleased I have the best products at my sport!

The combination of the Kogel Bottom Brackets, oversized derailleur and wheels bearings have made a huge difference to my ride time in all weather conditions from short XC races, to long endurance races ...no matter what the weather I never feel that drag in my pedals and my shifting stays super smooth!

Now to talk about the all mighty Kolossos. Last year we enjoyed experimenting with the Kolossos on the dirt which proved how strong it is. Getting slammed by giant rocks at 11,000ft in the middle of the mountains, you have the trust and faith that your adventure won’t end because of a weak pulley.
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.
DRIVETRAIN BLISS
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.
