OSPW OVERSIZED PULLEY WHEEL RIDEA EVO NEW SERIES SHIMANO R80XX / R90XX

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.   CHARACTERISTICS: Model name: Ridea OSPW+ RD6E60 Compatibility: SHIMANO Dura-Ace R9100-9150 amp; Ultegra R8000-8050 Cage: High resistance Forged Carbon composite with integrated bearing shields Upper pulley: 16t; X-ODON Technology; High resistance Forged Carbon composite; Ridea’s full ceramic #699 bearings Lower pulley: 20t; X-ODON Technology; High resistance Forged Carbon composite; Ridea’s full ceramic #699 bearings.
