TBH, this is my first bicycle flats in years, EXCEPT for having two valves separate from the tube this year... one ended up causing a blowout
(I wrote about this a while back here at BF).
I do like your idea on putting o-rings on either side of the rim... how do I go about getting some?
(this bike has Schraeder valves, while my tourer has Presta).
