Kogel Kolossos Oversized Deraileur Cages

Kolossos is the Greek word for a statue, much larger than the original subject. Sounds appropriate for replacing your 12 tooth pulleys with a 19 tooth bottom and a 14 tooth top pulley, built on the stiffest cage on the market.

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.

This model also fits  all 12 speed Red and Force wireless derailleurs for 2x setups, including the latest Sram Red groupset (2024).
