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

This CeramicSpeed OSPW RS Alpha cage with oversized rollers is designed to fit Shimano 12-speed Dura Ace 9250 and Ultegra 8150 derailleurs. This model is one of the brand's latest additions and therefore features the most advanced technologies. For its latest creation, CeramicSpeed has chosen to incorporate Alpha rollers with a modern design. By replacing the rollers' spokes with a solid aluminium disc, the assembly is more rigid, quieter and allows you to ride with peace of mind, knowing that no objects can get stuck inside.With this in mind, the bearing is fully integrated and protected by a dust cover to make it virtually impossible for debris to enter the bearing. The carbon cap has also been updated in terms of both design and construction. Its modern design will blend in perfectly with today's bikes, while its reinforced carbon construction makes it more resistant, thus increasing its lifespan.
