Thanks Boog.
Point taken, hence the heads up. Fortunately, on the few occasions it's happened the rear has gripped when it re-established contact with the tarmac, so far....
Did someone mention pink?
CF front std rear. Difficult to tell if it improves acceleration, but the lighter weight and sharper profile of the tyre makes it turn in a lot easier. Beware that the lug on the bottom of the frame, where the mainstand would be if it had one, is the next thing to grind when the pegs fold up, or wear away.
