Wheel selection

From what I've read Alex rims are basically a beginners wheel,

to acceleration and climbing?


Nope... I agree with Vee. You won't see a significant performance
benefit. If you want "fast" wheels you need to focus on aerodynamics,
but unless you are racing it is silly to worry about that, too. The
wheels you have should be fine, with the likely exceptions of:
a) too little grease in the hub, and
b) no stress relieving, and
c) too little tension in the rear wheel.

That doesn't mean that the wheels are "bad" at all... it's just normal
for inexpensive machine-built wheels. In my experience, dirt and water
will get in the hubs after a couple of rains because of "a", and spokes
on the non-drive side of the rear wheel will start popping after 2,000
miles or so because of "b" and "c".

Unfortunately, the wheels you get from Performance would probably have
the same problems, and you wouldn't have a local shop to take them to
(unless there is a Performance nearby). You should have at least a one
year warranty from Trek, and if it is a good shop they will take care
of any issues.

BTW, you can easily "tune" the wheels yourself with a little education
and a few tools... and then they should give you fine service.
