Outpowered cycfceceramic derailler for Shimano 12v

1. Aluminum pulleys and carbon plates: The cycfceceramic oversized pulleys are equipped with aluminum pulleys worked with precision, combined with light and resistant carbon plates. This combination of materials guarantees a significant reduction in weight while providing higher resistance, perfectly suitable for road needs. Their elegant and aerodynamic design improves the overall aerodynamics of the transmission, helping you earn speed and efficiency.
2. Ceramic bearings technology: The cycfceceramic oversized pulleys ceramic bearings are specifically designed for Shimano Dura 9250 DI2 DERAGERS and ULTEGRA 8150 DI2. With these high quality bearings, you will benefit from a remarkable reduction in friction during travel changes, with consequent more fluid transmission and significant energy saving. Enjoy a more efficient pedaling experience, optimizing your performance during climbs and sprints.
3. Tested by Frits Facts: The deraillers with Cycfceceramic Pulleys bearings have undergone rigorous tests by Frictions Facts, an independent laboratory specialized in the analysis of friction and the efficiency of the transmission in cycling. The test results have confirmed that cycenceramic ceramic bearings are among the fastest on the market, with a friction measured by alone 0.033W . These exceptional performance guarantee an ultra efficient transmission, allowing you to gain speed and precision during your rides.

Compatibility: The cycfceceramic oversized pulleys are perfectly compatible with the Shimano Dura ACE 9250 DI250 deraillers and Ultegra 8150 of2, providing you with a tailor -made solution to improve the performance of your transmission.
