Great thanks jenks. I have added them.
LaCap is the tech man I will make my name gat if I start dishing out advice but I have done full services including valve clearance adjustment with the basic tools I have.
I've had no breakdowns but have spare cables, tyre levers, patches, a spare 4mm tube, master links etc that I take with me on longer trips together with the duct tape and pratley putty!
