CeramicSpeed UFO Chains
From $129, Ceramicspeed.com
The draw: Maximize watt savings
“UFO” means “Ultra-Fast Optimized.” CeramicSpeed takes the best chains in the business and bathes them in a proprietary low-friction coating. The initial coating lasts about 200 miles, after which CeramicSpeed’s “Squirt Lube” should be used for maintenance. Independent lab tests showed up to 5 watts of savings, while a well-cleaned Dura-Ace chain running a low-friction lube demonstrated savings closer to 1 watt.
