Any bike on a road is a road bike, but this roundup will focus on light and swift drop bar, pavement oriented (but not pavement specific), bikes. They might be classified as road racing bikes or endurance bikes, but they’re intended for the traditional road riding experience: smoother roads and higher speeds with a premium put on low weight, high stiffness, and vertical compliance. This style of bike usually forgoes versatility-enhancing details like rack and fender mounts, but will often have the latest performance oriented-features and technologies like aerodynamic tube shaping to cut through the wind, and integrated bar, stem, and seatpost for weight, stiffness, aerodynamics, and aesthetics. One of the most recent trends to hit this category is disc brakes, which not only has made stopping more confidence inspiring in all conditions, it has also improved tire clearance on most models so riders can enjoy the benefits–more comfort, more traction, and in many situations, improved rolling efficiency–of wider, lower pressure tires. Disc BrakesWhat began with a trickle about four years ago is now a full-on flood: disc brakes. More and more we’re seeing race-oriented road bikes laun...
