Ridea OSPW RD6 E60 EVO ver.2021(for shimano 105)

brand new in box. Ridea OSPW Oversize Pulley Wheel System RD6 E60 EVO ver.2021 for Shimano 105. Ridea In 2020 we introduce a new evolution for our OSPW+ series with the E60 series, where the E stands for EVO. The E60 series is an almost complete redesign from previous C60 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. Now, as an option you can use lower pulleys up to 22t for your TT or triathlon bike for an ever-greater moment of inertia and power saving.
