Inertia Extreme Pulley Wheel (IEPW) evo series is the new evolution step in our big pulley line. The E48 series is an almost complete redesign from previous C48 series.
Both cages and pulleys are made of Forged Carbon composite. This material can be shaped into complex forms, allowing us to increase the thickness in critical areas for a better resistance cage, while yet reducing the average weight by 10 grams from previous generation. Evo cages also integrate the pulley bearing shields to save weight and to increase clearance between the pulley and the cogs.
All the pulleys in the E48 series include X-ODON narrow-wide teeth design.
