Bit out of the way but the Albany in Twickenham, used by a local bike shop and cycling club, plenty of benches out the front in the walled garden and no problem stacking bikes 10 deep here there and everywhere!
My favourite; New York mini, Normal New York and the big f*** off New York chain. Yes it makes me look like a Kryptonite salesman however it stops my bike becoming a thieving little oiks toy until he can get £30 for it.
Does bum fluff count as a Movember entry? I try every year and end up looking like I've got special needs!
