Disc brakes are a caliper-style brake that is attached to the wheel hub instead of right on the frame. They have been used for years in mountain biking because they offer powerful braking and come with suspension forks for better control over rough terrain.
Now, people are starting to use them in road bikes too! These breaks work much like traditional rim brakes do when you squeeze the levers on your handlebars but offer an extra level of stopping power and will make it easier to stop quickly if needed.
The increased leverage from having both hands near each other at all times provides more confidence as well which can be crucial during high-speed descents or sudden stops while riding downhill. It’s important not just for safety reasons, though; disc brakes make it easier to control your bike when you need to stop due to traffic, rain on the road or an upcoming turn.
