Sistema de polea de gran tamaño CeramicSpeed ​​con revestimiento aerodinámico - Shimano Dura-Ace 9100/Ultegra 8000 Info

El sistema de polea de gran tamaño CeramicSpeed ​​es el secreto para aumentar la eficiencia de su desviador mediante la reducción de la fricción. Esta versión está optimizada para sistemas Shimano Dura-Ace o Ultegra de 11 velocidades. Esta versión cuenta con cojinetes recubiertos, lo que genera una eficiencia excepcional y una vida útil muy prolongada de rendimiento como nuevo. Este recubrimiento los hace un 75 por ciento más duros que el acero. Se ha agregado una jaula de carbono aerodinámica para ayudar a los corredores a mantener su ventaja aerodinámica y moverse más rápido que nunca. Esta versión cubierta del OSPW es perfecta para triatletas y ciclistas de contrarreloj. Ha visto acción en las principales carreras del World Tour y Ironman. La polea superior tiene 13 dientes, mientras que la inferior tiene 19. El sistema de polea de gran tamaño CeramicSpeed ​​Aero lo ayuda a aprovechar al máximo su grupo de carretera Shimano de 11 velocidades.

The RA Perspective

We appreciate that CeramicSpeed actually puts a number on this one — 2.4 watts of savings as a starting point, according to their own testing. That's more transparency than most drivetrain "efficiency" products offer, even though it's still the manufacturer's number and not an independent lab result.

The aero carbon cage is the real differentiator here versus a standard OSPW system. If you're running a TT or triathlon bike where every watt of drag matters, that cage shape is doing something a standard cage isn't. On a road bike where aero isn't the priority, you're mostly paying for the friction-reduction case and the coated bearings' long-term durability.

Coated bearings are the tradeoff worth knowing about: they're not full ceramic hybrid bearings, so if you're comparing this to CeramicSpeed's ceramic-bearing options, this is the more accessible tier, built for durability and value rather than the absolute lowest friction CeramicSpeed makes.

We'd point this at time trial and triathlon riders on 9100 or 8000-series Shimano who want the aero and efficiency case in one part, rather than casual road riders looking for a marginal upgrade.
