These brakes were attached via a single bolt in the fork crown and the rear brake bridge.Ĭentre-pull brakes were the norm in the peloton (more on these later) until the introduction of the legendary Campagnolo Record sidepull brake in the early 1960s, which was both lighter and nearly as powerful as the centre-pull design. With these, both arms rotated around a single, centred pivot, which theoretically allowed the brake to self-centre and track an out-of-true rim more effectively than a dual-pivot brake. In days gone past, single-pivot caliper rim brakes were the norm. Single-pivot caliper brakesĪ retro cycling trend that won’t be coming back into fashion. There’s a wide variety of different caliper brake designs out there, and we’ve explained some of the more common types below. Bikes equipped with rim brakes are also usually significantly cheaper than their disc equivalents, even if they’re hard to come by on the latest releases. That said, a pair of well set-up rim brakes on alloy rims are more than sufficient for nearly all riders.

It’s for those reasons, plus the opportunity to fit wider road bike tyres and to make carbon rims lighter if they’re not used for braking duties, that modern road machines have moved substantially to disc brakes. They’re lightweight and can provide strong braking, although they’re much more susceptible to performance degradation in the wet than disc brakes.īraking performance can be degraded on carbon rims in the wet too, and there’s a risk of overheating with prolonged braking on carbon brake tracks. Side-pull caliper brakes were the primary choice for road bikes for decades. Some riders still favour rim brakes thanks to their simplicity and low weight. However, most mid-to-high-end bikes with disc brakes will have a hydraulic system for good reason. Hydraulic disc brakes vs cable disc brakesĭue to the frictional loss and stretch in the cable, cable-operated disc brakes lose out to hydraulics both in out-and-out braking force and modulation, but the best models are still more efficient than the majority of rim brakes.Ĭable disc brakes are a cheaper option than hydraulic brakes, so are often found on lower-spec bikes, and are easier to fix out in the wilds. The rotor pushes against a static inboard pad. SRAM’s Avid cable-operated disc brakes only move the outboard brake pad. The cable pulls a lever on the caliper, which usually pushes a pad on each side of the caliper into contact with the rotor. In a cable-operated disc brake (sometimes referred to as a mechanical disc brake), the physical connection between the lever and the brake caliper is made with a wire cable.

Still, we’ll give you a full rundown at the end of this article. There are other brake designs out there, but they’re a rarity on mainstream bikes. V-brakes (also known as direct-pull cantilever brakes) are operated via a cable that runs from one side of the brake and across the top, pulling the two halves together. These also work on the rim and are attached to frame bosses on either side of the wheel. On that note, and as we mentioned at the top, mountain bike disc brakes have been commonplace at all levels for years, providing powerful stopping power uninfluenced by trail conditions.ĭisc brakes and caliper rim brakes take the lion’s share of braking duties across most bikes, but you’ll also find V-brakes on some cheaper urban or commuting bikes. There are good reasons for that, mainly related to more efficient and consistent stopping, whatever the weather. Over the past five years, road disc brakes have rapidly taken over from rim brakes, which push brake pads against the wheel’s rim. We’ll go into different types of disc brake below. The majority of new bikes, whether that’s road bikes, mountain bikes or hybrid bikes, now use disc brakes that operate by pushing pads housed in a caliper against a brake rotor attached to the wheels’ hubs. There are three main types of brakes on modern bikes: disc brakes, rim brakes and V-brakes.
V-brakes are still common on commuter and town bikes.
