I've been an infrequent commuter lately. Back on the bike today, heavily loaded rear panniers and a moments inattention in the dark and I hit a big hole in the pavement. My handle bars rotated down a bit and I was listening for a couple of snakebite flats. No flats (Schwalbe marathon plus) but I now have a flat spot on my rear rim. There is also a small crack at the spoke hole. I built it myself with Dyad rim, double butted spokes and Phil hub. I have a spare rim hanging in the garage but I hate to have ruined my first built rim. I've been riding it for about eight years. Lotsa miles.
Just wanted to share with a hopefully sympathetic audience.
