CERAMICSPEED pulley wheels Aluminum Coated | 12 teeth for SRAM Road AXS 12-speed | black
The derailleur wheels from the Danish company CeramicSpeed represent the absolute high-end solution for all drivers who want to get the most out of themselves and their material in the race and for whom every watt saved is more important than anything else. Derailleur rollers and especially their bearings have to compensate for a lot of friction. Depending on the translation, these rotate 4-5 times faster than the crank and thus benefit in particular from low-friction and durable bearing . The CeramicSpeed SpeedBalls balls are 15% harder than the competition and can absorb significantly more forces. They also have an incredibly smooth surface, which reduces rolling resistance to a minimum. All of these improvements have allowed the service life to be increased by 6 times.
Compared to the already high-quality standard bearings from CeramicSpeed, the "coated" version has a wafer-thin protective layer applied to the bearing rings. As a result, the latter become even harder, have a life cycle that is 60% longer and have even lower rolling resistance.
CeramicSpeed only uses the best materials and the latest technologies in production in order to always achieve the highest possible quality. All products are handmade in Denmark. Manual assembly eliminates manufacturing tolerances and always guarantees a 100% fit. So that you really only use the best on your bike.
The oil included in the scope of delivery is used for maintenance and has been specially designed for these bearings. Lubricants from other manufacturers are not recommended for this.
