Rima patches: F0 size on box in back. Box of 100 ~$17 or so. I no longer batch these, after realizing about 10 yrs ago
that the # to fix had risen to 17 tubes. The conundrum of tubes with 'no holes' on under water leak test is always
frustrating. In the past I would re-install on an old wheel, pump up to 100# and set it to incubate. If it went down it
was tossed, if not it would be used as potential on-bike spare. Now I just toss them. I always carry two after ~15 yrs ago having a double
flat after side-swiping a curb when a car at a stop sign started to pull out when I was making a L turn. Pulled the
tubes out of the under seat bag and both had holes rubbed in them by loose tools. Tools since then always double
bagged in zip bags and tubes in their zip bags.
