In 2020 we introduce a new evolution for our OSPW+ series with the E48 series, where the “E” stands for EVO. The E48 series is an almost complete redesign from previous C48 series. Both cages are completely new and made of Forged Carbon composite. We have increased the thickness in critical areas for better resistance while yet reducing the average weight by 10 grams. New cages now integrate the pulley bearing shields to save weight and to increase clearance between the pulley and the cogs.
