which spare tubes?
Although we're travelling on tubeless tyres, we want to take some spare tubes along. Storage space is limited though, I don't really want to pack four different tubes, if I can help it.
Our tyre dimensionen are (front, rear):
bike 1: 110/80-18, 150/70-17
bike 2: 110/70-17, 130/70-17
Tubes are flexible and tolerant, they say. A near fit is good enough in case of emergency, right?
If this is correct, which tube dimensions should we take along at least ?
