El nuevo OSPW tiene mayor resistencia y durabilidad, con un diseño de jaula reforzada que garantiza un rendimiento óptimo incluso en las condiciones más exigentes. Esta versión es compatible con su grupo electrónico Shimano Dura-Ace Di2 o Ultegra Di2, lo que le ayuda a seguir siendo eficiente y funcionar lo más silencioso posible. También cuenta con los innovadores discos Alpha que son completamente macizos para proteger los rodamientos. CeramicSpeed ​​OSPW siempre está evolucionando para hacer que su viaje sea más suave.

The RA Perspective

Of the CeramicSpeed pulley systems we carry for the current Shimano Di2 groupsets, this is the one we point most riders toward first. It's not chasing the aero gains or gram-counting of the pricier options — it's a durability upgrade with a real, sensible mechanism behind it.

The ADR bearing protection is the feature that actually matters day to day. Standard pulley wheels leave the bearing exposed at the spoke gaps, and that's usually where grit and water work their way in over a wet winter of riding. The sealed, self-clearing design here is a genuine improvement, not just a marketing bullet point.

The tradeoff compared to the aero or titanium versions is straightforward: no aerodynamic shroud, and aluminum construction instead of titanium, so it's a bit heavier than the top-tier options. For most road riders that difference is irrelevant. The lifetime warranty also takes some of the sting out of the price for anyone hesitant about spending this much on pulley wheels in the first place.

We'd recommend this to a rider who wants a meaningful upgrade over stock Shimano pulleys and values durability over squeezing out the last watt of aero savings.
