Choosing 700C-Brakes for Road Bike
Are there any recommendations on calipers to select for a road bike's 700C wheels. Things to consider would be quick release function, whether they should be side-pull calipers, and whether they can accommodate 25mm-28mm tires?
For example, my touring bike's side-pull calipers are made by Tektro (model R556) ... to accommodate both wide tires and fenders. Are side-pull calipers recommended for road bikes with 25mm-28mm tires?
What factors should I look for (i.e., should they be side-pull?), when selecting brake calipers for a road bike? Here is one factor, when addressing the OP, of which brake calipers to choose for a road bike:
* Quick Release function ... ease of taking front wheel off and on (bike to be transported in trunk of car).

Almost any short-reach sidepull road brake will accommodate 28mm tires and, of course, smaller. They are the standard for braking sets on almost all road bikes that aren't designed to accommodate larger tires and fenders.
The frame design will determine whether you "have" to use sidepulls or not. Centerpulls and cantis require pivots, usually brazed-on, and cable guides that center the cable over the midline at the rear, and in front. If there are no such accommodations on the frame and you want to still accommodate bigger tires and fenders (assuming enough clearance, of course), then long-reach sidepulls is an option.
There is a horseshoe-shaped device for converting a center-brace-mount bike to centerpull-fitting brake. It is a kludgy workaround if you are determined to have centerpulls on a sidepull brake frame.

On the q/r - if you don't have the release in the lever then make sure your calipers have a release, ie. don't buy Campy calipers to go with Shimano levers.
Dual pivot brakes (in general) have more stopping power than single pivots.

I have had trouble clearing regular "short reach" brakes with 700x28 Armadillos on 2 bikes. The first was a1990 Diamondback with 105 brakes and the second was a 2004 or 05 Trek 1500 with some other brand (stock) brakes. The D-back was so close I swear a grain of sand would rub and the Trek was hard on small pebbles.
