CeramicSpeed OSPW RS Alpha rear derailleur hanger for Shimano Ultegra 8150 / Dura-Ace 9250 12-speed

This CeramicSpeed OSPW RS Alpha pulley body and its oversized pulleys are designed to fit Shimano 12-speed Dura-Ace 9250 and Ultegra 8150 derailleurs. This model is one of the brand’s latest releases and therefore features the most advanced technologies. For its latest creation, CeramicSpeed has chosen to incorporate Alpha pulleys with a modern design. By replacing the pulley spokes with a solid aluminium disc, the assembly is stiffer, quieter and allows you to ride with peace of mind, knowing that nothing can get stuck inside.

With this in mind, the bearing is fully integrated and protected by a dust cover, making it virtually impossible for debris to enter the bearing. The carbon cage has also been updated, both in terms of design and construction. Indeed, its modern design will blend perfectly with today’s bikes, whilst its reinforced carbon construction makes it more durable, thereby extending its lifespan.
