And take the flats you've already had as an indication you may want to watch the road a bit more carefully to avoid the trash that'll puncture your tire and tube.
I want to learn how to repair a flat, but especially for the rear tire it looks involved and something that I might not be able to do. How involved is changed a rear flat?
Also (and perhaps dumb question), if a nail goes through the tire, the tire should still be ok? Just the tube would either need to be patched and/or replaced?
