CeramicSpeed refers to their Oversized Pulley Wheel System as the fastest on the planet. The 13-tooth upper pulley wheel and 19-tooth lower pulley wheel optimize the performance of your Shimano Dura-Ace rear derailleur. According to CeramicSpeed, this system saves 2.4 watts over the standard system. Accumulating tons of energy conservation over a long period of time makes this system a top choice of some of the cycling teams and triathletes in the world. This coated version gives it a guaranteed lifespan of six years thanks to a metallic layer that is 75 percent harder than steel and resistant to corrosion. This upgrade is worth it for a fast and long-lasting system.
The best way to install your OSPW system is to go through a professional mechanic. During travel, it is very important to remove the entire rear derailleur with an Allen key to avoid damage or to even fit in travel bags. It is also important to lubricate the bearings in your system to increase the longevity of and make the most out of your system. Adding oil to the lubrication points on the back of the cage plate lets the oil penetrate the bearings for proper lubrication. With proper care and installation, your CeramicSpeed OSPW will be a great addition to your fastest bike.
