Flip a few more pages in Bicycle Retailer and discover that Clay Mankin, of City Cycle in San Francisco, died of natural causes on a road ride November 13.
Toss Clay's name into Google and you'll get a ton of information about his life, so I won't add a link to any single item here.
Oddly enough, I became acquainted with Clay and City Cycle in 2001 when I was searching the web for a source of slotted cleats. He responded to my email, sold me his last half-dozen sets of Sidi slotted cleats for $20 (shipping included) and threw in a coffee mug I still use on mornings I need inspiration to ride.
In that brief exchange I definitely got the impression Clay and his shop represented good things about cycling. The tributes in print would seem to bear this out.
