I really like 26x1 3/8. It's one of the sizes that's hard to find here. My options seem to be have them shipped from Asia, buy wheelchair tires (making sure they have the tread centered, most the performance tires have the tread offset), or get them from Walmart (not kidding, most convenient source). For wheels I can pay for custom build or find an old bike that has them (invariably chromed steel rims).
If it wasn't for the cost of shipping I would love to trade parts readily available here for parts readily available there.
