" had a flat while riding my 76 Masi yesterday and it took forever, it seemed, to get a rideable pressure in my spare sewup using my silca with campy metal head. Fellow riders were amused and suggested I enter the modern age and use CO2 cartridges. Are they safe for sewups? Any gotchas?
Thanks David Manderscheid"
I only carry CO2 when riding tubulars. Since there's no issues with trapping a tube or not getting a bead seated there's no negatives to using a cartridge.
And it's going to give you 100+ psi depending on the cartridge size, which is imperative for keeping a spare tubular which will not have much glue adheasion on the rim. As well as getting you back on the road in a couple of minutes.
Win, win, and fits in your jersey pocket.
