Description
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.
