CeramicSpeed ​​OSPW RS 3D Titanio 20.º aniversario Shimano 9250/8150

We don't see many of these — CeramicSpeed only made 200 of the 20th Anniversary OSPW RS worldwide, and most of that run went straight to select dealers rather than sitting on a shelf. If you're the kind of rider who already runs CeramicSpeed bearings everywhere else on the bike, this is the version that makes sense to chase down.

The 3D-printed titanium construction is the real story here, not just the anniversary branding. Hollow titanium pulleys are a genuinely different manufacturing approach than the machined aluminum CeramicSpeed uses on its standard OSPW RS, and the numbered cage plate means the one you get is yours specifically, not one of an anonymous batch.

We'd be straightforward about who this is for: at just under $3,000, it's not a marginal-gains purchase in the traditional sense. The friction reduction comes from the same coated ceramic bearings CeramicSpeed uses across its lineup, so a standard OSPW RS gets you most of the functional benefit for a fraction of the price. What you're paying the premium for is the titanium build, the limited numbering, and owning a piece of the brand's 20-year history rather than just its current catalog.

If that's the appeal, this is exactly the piece to build a drivetrain around. If you're chasing pure watts-per-dollar, we'd point you toward the standard OSPW RS instead.
