Kogel Kolossos Oversized Pulley Cage

Greek for a statue larger than the original; “Kolossos” is a fitting name for this oversized pulley cage. Designed to deliver maximum drivetrain performance; the Kolossos Oversized Pulley Cage enables you to go faster with less effort by reducing drivetrain friction; improving shifting accuracy; and enhancing chain retention. The Kolossos pairs an incredibly stiff; aircraft-grade aluminium cage; which combines drivetrain precision and power transfer; with two oversized pulleys-;a large top pulley and an even larger bottom pulley. This design reduces chain articulation due to the larger pulley wheels; decreasing drivetrain friction for a smoother ride and improved energy transfer from the pedal to the tarmac. Additionally; the long tooth profile on the lower pulley improves chain retention where it is most needed; further enhancing the overall performance of your drivetrain.
