Thanks all for your comments.
Never heard of rotor cuff so I'll have to that look up and see what the symptoms are.
Rich, agreed about the pressure gauge and getting the tyre pressures correct, I will be ordering one of those gauges shortly as I've got a cheap Asda thing and could finally do with a decent one.
I've got ACS strings and wondering if the pressures may need a slight adjustment from the door card pressures. May do a some experimenting with this, I can always set them back to what they should be.

Also, I've moved the seat a little closer tonight so I'll see how that goes. Although I don't want to change too many things at once!
