Got some 26x1.5 slicks for my bike, so got them on today. I somehow managed to puncture one of the tubes, and as Murphy says, I had no spares or workable patch kit. It would be no good to have a patch kit, though, because I can't for the life of me work out where the tube is leaking, though it does leak and fast, I suspect the valve, but can't see any bubbling from anywhere under water. In any case, got some new tubes from
Halfords (I have a spare now) and got the new tires sorted. The ride feels nice, and a lot quieter than with the knoblies, but haven't noticed a lot of difference in speed, will see. Also cleaned and greased the pedal bearings, which were starting to be a bit sticky.
