When the rest of the build is top shelf, the derailleur cage tends to get a little more attention too.
The new CeramicSpeed Shimano OSPW RS System uses an injection-molded carbon-fiber-reinforced PA cage with customizable spring tension for dialing in the setup.
Shops can choose between alloy 5-spoke pulleys with handbuilt CeramicSpeed bearings or ALPHA disc pulleys featuring ADR bearing protection, with a Team Edition ALPHA option available for an even more distinctive finish. Warranty coverage is four years for the 5-spoke version and lifetime for ALPHA.
Plenty of options for putting the finishing touch on a premium Shimano build.
