I took my bike out the other day and got a screw in the rear tire. Ouch ! It had less than 1k on it. I plugged it, fired a can of fix-a-flat into it and got it home. I mount my own tires on a homemaid jig, "So" I thought "why not put a tube in it". It's a 130/90- 16" I'd be grateful to anyone who has info on what size/type of tube to order.
