From afar, Force looks like Red's twin, much in the way Rival used to look like Force's twin. The big change is that the arms that support the brake cable-housing stop look thinner, more graceful. From the side, the cutouts are bigger. They call it a skeletonized design. The differences that separate these Force calipers from Red start with the color. The finish here is a nice grey anodizing, called Zephyr Silver, rather than polished like Red. The brake shoes don't have the cutouts that the Red shoes have, and while you may not be able to see it, Force doesn't have the titanium bolts and such that Red calipers have; instead, they rely on stainless steel parts. Like Red, the Force calipers use cold forged aluminum for the arms.In terms of function, Force is nearly identical to Red. There is a hex-head spring tension adjusting screw on the side to adjust the feel of the squeeze. There is also a hex-head screw atop the calipers for easy centering. The brake shoes come with SwissStop pads manufactured to SRAM's all-weather spec.The SRAM Force Brake Calipers come two to a set. The quick release is indexed for precise opening and closing, and there's a micro-adjusting barrel against the cable housing. The brake pads are replaceable with any Shimano/SRAM-compatible pad. The claimed weight of the SRAM Force brake calipers is 280g per set.
