Avoid Serfas products!!
After having discarded a K-2 size mountain of malfunctioning gear, my choices are:
lights - Trek, Mars or Blackburn. within these three price directly reflects quality. Keep the receipts, not all lights fit all frames and handlebars.
pump - blackburn airstick, the one that's rated to 160 psi.
saddle bag - any old thing will do, just make sure it is expandable. Have 2 - I repeat - 2 spare tubes and patch kit on top of it.
Leatherman-type tool to pull burrs out the tire. Sears has pretty decent thing for about 10 bucks - blue plastic-covered handles.
