If the TPS-1 has the double sided head that is on
my TPS-2, then it's certainly better in that respect.
The issues I have with the head are:
-- On schraeder valves, you must attach it very firmly
and make sure the valve stem is as deep in the head
as you can, or you won't get an accurate pressure
reading from the gauge on the pump
-- The head has a piece that you twist to engage it, and
it's somewhat difficult to twist/untwist; and you
can lose air while engaging/disengaging
-- I fear breaking presta valves while engaging/disengaging
the head with that twistage
-- I feel that I lose too much air while removing the head
Well, I think I ought to retract my earlier reccomendation
of the TPS-2. Obviously, I don't like the head; and I'm not
confident that the shaft won't break, either, so the only
thing I like is that I can, in fact, get 125 pounds quickly
into a road tire, and 65 pounds easily into a MTB tire.
