And about that spare tire. You probably don't really need one if riding near civilization where bike shops with full and varied inventory proliferate and no pandemic-related supply problems occur. Sure, they might not have exactly what you prefer to put on your bike but they'll have something that fits, right? They don't always. Touring in France in '74 it never occurred to me that small town bike shops would not stock 27" tires. I needed one and there were none. 700C, 650B, sewups; no problem. Had to take a train to an actual city to find a 27". Who'd a thunk?
