OSPW+ C26 series has been designed to meet the special requirements of Birdy bikes due to their shorter chainstays and RC angle. Furthermore, to increase chain stability and smoother gear shifting, even with 32T cassettes, C26 series include our narrow-wide teeth technology X-ODON in both pulleys, now available also in alloy with matching colors with the rest of Ridea parts for Birdy bikes.
Available options: bearings can be upgraded to Ridea’s full ceramic #689 bearings. Pulleys can be chosen in 7075 alloy in red, gold and silver colors (more custom colors are also available upon special request)
Available accessories: RDH L28 (rear derailleur bracket axle extender recommendable with some gears and frame combinations); RD W15 (rear derailleur hanger washer; increases changing performance on the smaller cogs with certain gears and frame combinations)
