Had these for a while now and they're great. Just come back from a long trip round France and wore them every day (managed to wash them occasionally in baths and sinks!) and my bum was absolutely fine! Did end up with some very sharp tan lines... but that was my fault.
Just been on a 400 mile ride round france with some hefty panniers and this did the job beautifully. Couldn't work out the pump fitting bit but didn't need it so don't base you're purchase too much on that.
Got this for a cycle trip down the west coast of France. On the whole it did the job pretty well and I loved not having to fiddle with loads of wires when fitting it. The main thing that let it down is it can't handle super fast speeds! Anything over 35mph (which to be fair you don't often hit unless you've got some good hills) and it just shows 0. Bit annoying.
Otherwise all the settings are pretty good and I think accuracy was bang on.
Found this book really enjoyable to read, which I wasn't really expecting from a book on trading shares. Everything in it is put in a way that makes absolute sense which makes it so much easier to remember. Im sure there are other books which go deeper into different trading strategies but personally I think everything you really need to know about trading is in this book.
