OK, after my 3-flat Christmas Eve extravaganza where I ran out of CO2, I figured it's time to join the ranks of the frame-pumperati so I picked up a Topeak Road Morph G
I think the thing that frustrated me more than having to finish my flat-shortened ride on soft tires was not being able to find the leak the first times! Frame pump should fix that nicely, although I'll still carry CO2 because it's way convenient.
