cyccomte has a good point. Get a decent pump or you will be cursing yourself when you get a flat. The really small pumps are a PITA to use, IMO. Like imi, I carry a spare tube, patch kit (both traditional and scabs), pump, tire levers and a pair of vinyl gloves.

I suggest a practice run or two, especially on the rear wheel, so you get used to dealing with the RD an chain.

Thanks, folks, for the suggestions on the Rema Tiptop patch kit. I'll have to look into this - are these found at my LBS or auto parts store?
