I'll start this off with a double whammy.
Spotted these holes in my rear rim while at work, so had to ride home very gingerly using front brake only.
Big hole:
Small hole:
Then on the way home there was a big bang as I hopped up a kerb and I discovered that I'd cracked the seat clamp, had to ride standing up after that.
The upside is I do want to learn to build wheels so it's a perfect excuse to look for some sunsets to replace the 521s. And the post is USE, so replacement clamps are available.
