Drivetrain & Brakes

Used this for a new gravel bike build. I had never installed a bottom bracket before and this was very simple and straightforward. Came greased and ready to install. Because of the factory grease, it doesn't spin extremely free to start, but it's loosening as it breaks in.

In 2022 my goal was to climb 1,000,000 feet (accomplished). So, while climbing about 3,000 feet per day I broke three of these chains in four months (and was fastidious about checking their stretch). Switched to a Red 22 chain and had no problems thereafter. I love this KMC chain, but the minimally constructed links just don�t work, for me, with considerable daily climbing. In a normal year, say 500,000 feet of climbing they perform flawlessly. Also, my experience is that they stretch a bit more quickly that a Red 22 or SRAM PC11 chain, but given its lightweight and minimal design this isn�t a surprise. All that said, it is still my preferred chain (unless on a long term climbing mission).


Bought this to use with Campy EPS (11s) and non-Campy freehub wheel. Cassette range also outside Campy spec (11-28)...but it all works like a charm! Excellent, fast, no stumble shifting, only minor rear derailleur adjustment, 2 minutes, ready to ride. Durability with waxed chain TBD.
