Product Description

Greek for a statue that is 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 will enable you to go faster with less effort. It does so by introducing lower drivetrain friction, for improved shifting accuracy and better chain retention. That's because it 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. The chain articulation is reduced due to the larger pulley wheels decreasing drivetrain friction, for a smoother ride and improved energy transfer from the pedal to the tarmac. The engineering of the pulley wheels doesn't stop there, since the long tooth profile on the lower pulley gives better chain retention where you need it. Designed for World Cup use, the Kolossos Oversized Pulley Cage is available in a wide range of colours, allowing you to customise each individual component and make your bike look as individual as those ridden by the pros. Features A custom, oversized derailleur cage for your derailleurs. With premium ceramic pulley wheel bearings. Reduced chain articulation reduces drivetrain friction for improved energy transfer. Aircraft grade aluminium cage for shifting precision. Lower pulley wheel designed with a long tooth profile for improved chain retention. Pulley wheels, assembly screws, stop pin, front and back cages and pulley covers available in a choice of colours. Derailleur not included. Installation typically requires replacing your chain to accommodate larger pulleys. Also requires disassembly of the stock cage. | Merlin Cycles are one of the longest running online bike stores in the UK.
