  1. Is it OK to use a 32mm tube in a 25mm tyre? It cannot be very neat
    inside there.
    This is for an old 27" wheel, and I'd like to keep using schrader
    valves (for perverse reasons best not argued here.) Tubes smaller
    than 1¼" are hard to find. I know a 700C is close enough.

    If you wind up with a fold your tube will have a very short life. But then,
    tubes are undersize to start with, so get one and try it. If it looks like
    it will have a foldover in it, give it up.

    32mm in a 25? It may work... in throes of desperation I tried a 35 in
    23 - forget it, it doesn't fit. I had to make (another) trip to the
    shop...

    Bummer. Thats what I was afraid of.

    Its hard to get the tyre on at all. Very hard over the big tube without
    pinching a hole in it. Tyre levers essential, if only to shove all
    those rubber folds out of the way :-)

    Anyway, my order from the US finally arrived, including nice
    Japanese kevlar-belted 27" touring tyres. Am happy.

    Pasela Tourguards? They have an excellent reputation. I very nearly
    imported some myself but in the end went for slicks. My Fasgrips arrived
    from America today, so I'm happy too.

    Yes, thats the one. They have the usual fine tread, which I think is
    purely cosmetic. Completely useless, but doesn't do any harm either?
    Except maybe provides some thinner spots for the thorns to get through?
    I hope the aramid (kevlar) does its job.
    Only US$17 from aebike.com .
