I love new tyres. I’m a bit scared of them, thanks to the dire warning stamped in red on my bill about taking it easy for the first 200 miles. This is only my third set of new tyres ever, the bike came on Michelins which wore out and were replaced with Metzelers in 2004. Now we are on Avon RoadRiders (why couldn’t they have been roadrunners, would have been much more fun trying to ride out past cliff edges and paint my own tunnels on the side of mountains). 350 quid worse off, thanks to an unexpected bill for trucking the stricken beast back up the M1 to Flitwick – my cunning plan to use a temporary repair kit was foiled by the presence on an inner tube – but for at least a little while (until I square them off) I am revelling in the joy of truly 3D movement.
