Shimano's 6800 series chain is for use with 11 speed drivetrains. It has their proprietary SIL-TEC PTFE coating, increasing its life and shifting efficiency while helping decrease chain noise. While not as light as Dura Ace it is lighter than the previous Ultegra offering. So if you need a Shimano 11 speed chain but Dura Ace is a little to rich for your blood, Ultegra 6800 has you covered.
Still rockin' 10 speed? Me too. Take a look at our selection of 10 speed chains here.
Great value, quality construction, the only thing i could ask for is that Shimano would supply a master link with their chains instead of the one-time 'pin'. Other than that the chain is light yet durable and runs on both my Shimano and Sram cassettes without issues.
