Racing roadkill

In this weather I always carry 4 tubes, and a proper patch kit. If you carry a cloth with you, you can usually get the tube dry enough to take a standard patch / rubber solution, then put that tube somewhere to set ( bag / saddle bag / whatever). Hopefully, by the time that tube is the last resort necessity, it will have set adequately. I’ve only had 1 ride in all my time road riding, where I started to use the patched tubes, having used all 4 fresh spares.
