So, what are the odds of getting two flats in one ride? What would you do if you got a flat 10 km from home but only 20 min into the ride?
First, you are riding well, 30km/h for the first 20 min is good going... The odds, I don't really know but I would hate to have to turn around and head home for another tube or keep going for another hour without a spare tube.
What if you spot someone stuck on the side of the road and in need of a tube?
For this reason, I do think carrying two tubes is the way to go. As well as carrying a couple of sleeves (cuts of an old tube) in case something puts a hole on your tyre. Hey, they got me home once or twice...
