UFO Racing Chain Shimano 11s

This ultrafast chain has been optimised for Shimano compatibility, to boost the efficiency of your entire drivetrain.
 
CeramicSpeed UFO Racing Chains can save you between 2–5 watts on a distance of 600 km/370 miles. After this, you can apply the CeramicSpeed UFO Drip to reboost your racing chain. After the 600 km, you are still left with a highly performant chain, superior to a standard chain. When added to the full CeramicSpeed component upgrade (the OSPW System, Bottom Bracket and Wheel Kit), chain optimisation can take the total saving to between 10-16 watts.
When you need the extra advantage to make a real difference at the finish line, the CeramicSpeed UFO Racing Chain is the way to go.
