The Direct Curve 3 utilizes a sculpted design of cold forged aluminum to yield excellent strength. A more svelte design than that of the Direct Curve 2, it is the lightest model in the Direct Curve line. As with all of the Direct Curve brakes, the curved arms administer reliable stopping power without drag from noodles or linkages. Construction: Aluminum arms, cartridge brake pads. Spring tension and pad position are adjustable, but unlike the top of the line Direct Curve 5, the pad brackets and arms are not reversible.
