CERAMICSPEED rear derailleur wheels aluminum 12 teeth for Shimano 11-speed
The rear 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 who are concerned about every saved watt. Rear derailleur rollers and especially their bearings have to compensate for a lot of friction. Depending on the gear ratio, these turn 4 - 5 times faster than the crank and thus benefit particularly from low-friction and durable bearing . The CeramicSpeed-SpeedBalls balls are 15% harder than those of the competition and can absorb significantly more forces. They also have an incredibly smooth surface, thereby reducing rolling resistance to a minimum. With all these improvements, the lifespan could be increased 6 times.
The oil and grease included in the scope of delivery are used for maintenance and have been specially designed for these bearings. Lubricants from other manufacturers are not recommended for this.
CeramicSpeed uses only the best material and the latest technologies in its manufacture in order to always achieve the highest possible quality. All products are handmade in Denmark. Manual assembly eliminates manufacturing tolerances and guarantees a 100% fit. So that you really only install the best on your bike.
