Indicating and arm signals

Also signalling to pot holes etc for cyclists behind you (unless it's a nodder hanging off my wheel) is a good pratice and not just a 'roadie' thing.

I like those people.

There is some godamn awful hole in Haringey. It's on the side of the ride so the only way to avoid it is by going in to the lane more.

Haven't been there in a while though, hope they've sorted it. It's a really scary hole.
