100% Guarantee CERAMICSPEED Pulley Wheels Aluminum | 11 Teeth for Shimano Road 12-speed

CERAMICSPEED pulley wheels aluminum | 11 teeth for Shimano Road 12-speed

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 a smooth-running and durable bearing . CeramicSpeed SpeedBalls balls are 15% harder than the competition and can absorb significantly more force. They also have an incredibly smooth surface, which reduces rolling resistance to a minimum. Thanks to all these improvements, the service life could also be increased by a factor of 6.

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.
