You might learn a little about rims and tires at this link:

The new big problem is about the airfoil "x" marked rims. For most of
us the TA / Airfoil will be just fine. One way to save tire weight is
to get two tires. Use one to train on and the other for events. When
the first tire gets wore down after a thousand or so miles, change out
the tire and train on the new tire. Save the one wore down for events
only. You may want to sand down the tire tread shoulders as usually
for me the center of the tire wears out fastest.
I have done a one hundred mile day on the UDC 36 with the airfoil rim,
stainless spokes, ta tire, and air seat options. I did not get the
brake (trying to save weight). I have also done 20 plus miles without
stopping or leaning. (After about 20 miles usually nature starts to
call real hard.)
I will some time come up with a break set up but will only mount for
long down hill work. The long down hills end up wrecking my knees.
It rains a lot here and I commute daily all year. To maintain good
contact with wet feet and also to increase efficiency I went to SPD
pedals. Now I feel real uncomfortable when not clipped in. If you try
clipless pedals make sure you get real good at practicing getting out
of them before you start riding. First few days are a little scary.
Hope some of this is helpful.
