   Usually, when I'm posting in the "How-To" section it is with some advice. Today though, I'm looking for advice.

   For the second time in as many weeks I've been caught unprepared for a flat. The first time was on my way home and required waiting for a bus in the rain.

   Today, it happened just in front of my office, and leaves me having to TTC Bus it home since the subway is out of bounds during rush hour with a bike.

   I have a large pump at home, and all of the tools, I just didn't bring them with me...

   However, I'm looking at mini-pumps, can anyone recommend a brand of smaller pump that they are using?

   And, what kind of repair on the go kits do any of you carry?

   Thanks!

   I'm terribly unprepared, really. But sometimes I remember the small pump (that is still packed somewhere - just a Cdn Tire special - works great, though). The folding bike makes *sure* I have a pump as there's actually a pump integrated into the seat post. Haven't had to use it but it's good to have nonetheless. Apropos of nothing, I wish that bike didn't have presta valves...

   I googled Presta valves because I am no valve expert, and this is what I found, so I thought I'd share. :)

     The Presta valve (also called Sclaverand valve[1] or French valve) is a valve commonly found in high pressure road style and many mountain bicycle inner tubes. It is also now used on all tubeless bicycle rims[citation needed]. It comprises an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.

     Unlike Schrader cores, the inner parts of the valve, the valve core, in most cases cannot be removed from the stem. Some Presta products allow core removal but they are still quite rare. This has consequences for those who intend to add puncture repair fluids to the inner-tube; the usual way is to remove the valve core before pouring in the substance. Such users are reduced to buying ready-filled tubes or temporarily holing tubes for the filling process.
