Ahhh...if we're getting off the "legal" side then also a good puncture kit and a pump plus a few of the usual tools for your bike. And a good map even if you have a SatNav.

I'm never really sure about the legal requirement for HiViz jacket/bib and warning triangle in regards to a bike. I know they're both requirements for a car but I've never seen anywhere that they're not required for a bike. The Hi Viz isn't a real problem as they're easy to carry and lightweight but a warning triangle is a different matter. I take the view that if the bike breaks down I can probably move it off the road so its not a hazard and don't bother to take one.
