Road Bike Rim Brake Or Disc Brake
It s easy to understand why most people think discs are better for road bikes.
Road bike rim brake or disc brake. A rim brake bike applied braking force directly to the rim or sides of the wheel. Disc brakes by their position on the bike and the fact they are self contained are generally protected from wet conditions so wet weather performance is largely unaffected. I am about to buy a new road bike and there seems to be a host new road bikes with disc brakes i ve had a mountain bike with disc and it s fine just wondering what the pros and cons of having a road bike with discs apart from the looks should i stick with the traditional proven rim brake or have a more in depth look at disc brakes as the industry seems to be inclining towards discs. The italian brand already has the oltre aero road bikes in its range and has only recently launched the oltre xr3 but the aria represents a trickle down of aquila time trial triathlon design in a much more affordable and broader application.
It seems every company now offers disc brake road bikes. With a disc brake you don t get that slight delay in braking which is caused on a rim brake as it first has to displace water from the rim before biting on the surface. Here we set disc brakes vs rim brakes according to the most important criteria. Disc brake compatible bike frames also cost more than frames that are designed for rim brakes.
Bianchi offers both rim brake and disc brake versions of its aria aero road bike. Placed at the center of the wheel disc brakes earn their name from the disc rotor that is attached to the hub of the bicycle wheel. The propel advanced pro 0 2020 4 699 is a race ready bike with ultegra and slr deep section carbon wheels and an aero handlebar and stem. On the flip side a rotor that sits separately in the centre of the wheel handles the stopping power on a disc brake bike.
The brake pads cost a lot more than rim brake pads and while they would likely last about as on a road bike they require replacing quite often on a mountain bike due mainly to its heavier weight. More engineering is required to design and build the frame. So many marketing dollars focus on selling discs for every type of riding. Better is a broad word that covers a lot of ground just as road bike is a broad term.
Whereas a road bike rim brake traditionally attaches to a hole in the frame or fork and then uses the wheels circumference as its braking surface disc brakes are a little more complicated. The rotor is typically mounted directly to the hub much like a motorcycle or the car in your or your neighbours driveway. Its defy endurance bike might be disc only but there are five models of the propel aero bike with rim brakes and seven of the tcr advanced giant s lightweight all round road bike.
