The CeramicSpeed UFO Factory Optimized KMC 11-speed chain delivers outstanding drivetrain efficiency and performance. Engineered through a meticulous multi-step optimisation process in Denmark, this chain saves between 2–5 watts over 650 km (400 miles), offering racers and serious cyclists a true performance advantage.

Designed specifically for KMC 11-speed compatibility, the chain goes through precision polishing, deep cleaning, and double-layer waxing to ensure ultra-low friction. While ideal for dry conditions, it requires maintenance care in wet environments to preserve its peak optimisation.

After the initial 650 km of peak performance, CeramicSpeed recommends reapplying UFO Drip Chain Coating to maintain enhanced efficiency throughout the life of the chain. Note that while the watts saved will gradually decrease after this point, the chain continues to outperform untreated chains due to residual optimisation effects.
