The structure of the knee is a bloody good argument against intelligent design. Stupid things, they don't respond well to abuse and once you've tweaked one the only solution seems to take it easy. I'm guessing TT is turbo trainer. GWS

And yes re TT - the old Holdsworth 531
Designed by the sort of people who believe in Intelligent Design.
