Drivetrain & Brakes
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.
I bought these when the Shimano composite pads were unavailable and I�m glad I did. The braking performance is dramatically better. More modulation and power. They don�t squeal much in dry conditions but, wow, they howl in wet, grimy weather. I can live with it for the far superior braking. They are brakes, after all.
