I got my first puncture on the Triban because of an enormous pothole. I was following a 50 bus into town and it basically popped out from under the bus. There are also quite a few roads where it seems like there aren't potholes, just a sub-par surface - I see trenches running along the entire width of the road pretty often. They're almost always thin, but not thin enough to not be worth slowing right down for, and there's also often a tiny rise in the road surface on either side of them. Almost as if the tarmac is composed of stickers, and they're peeling at the edges.
