I could have done with this a few years ago when I did the London to Brighton. Why has no one thought of this before hand??
I was just looking at it and thought "those cups go" I'd get matching one to what I have in the bus for it. In fact I have them. I bought 6 today. 4 for the bus and 2 for Erm, owwww, oh yes, the bike.
I want to see someone fit one of these to a board of death I like the idea though but imagine how much more you could fit in if you had a tandem
