Best brake pads for road and gravel bikes reviewed 2025: our guide to the best replacements and upgrades

Riding fast is no longer just about who gets to the top first. Riders like Tom Pidcock and Matej Mohoric have taken big wins on the world stage in recent years thanks to their abilities to descend. So, It might sound counterintuitive but braking efficiently and slowing down could make you faster.

Of course, the whole brake system is vitally important alongside actually practising good descending techniques, but a relatively cheap highly effective way to find speed is to upgrade your road bike and gravel bike disc brake pads.

Different compounds and types of brake pads can offer different attributes, think about what feedback your brakes give you on a decent. Are they 'fading' or losing power as they heat up? Thats where pads like the SwissStop Exotherm 2 or Shimano L05A-RF with their cooling fins could be beneficial. Extending the pads reach out of the caliper and allowing the wind to aid in cooling the pad material.

Maybe your pads are wearing too fast or not offering enough modulation? Then consider the SwissStop Disc RS or BBB DiscStop HP pads both feature a high-quality finish that we found to be superior to the others on the test.

Brake pads come in a wide range of shapes and sizes which are specific to each model of disc brake and manufacturer. If you're unsure which pads will fit your brakes, get a shop to help or replace them for you. Your brakes need to work!

The Quick List

Best disc brake pads for road and gravel bikes

Best Overall

The thing that I noticed straight away is how quiet the pads are – even when brand new, in the dry, the pads seem lass raspy than many of the competitors, whilst delivering a similar amount of bite. They felt like they were already bedded in.

Other brakes almost feel slightly gritty to begin with or worse still, slightly glazed over, until you bed them in. Modulation to begin with is very good, but there is a very slight drop in performance when you really overwork the brake – I’m being critical here, because in all but very hot alpine conditions you probably won’t notice this.

I tested all the pads on the same Shimano Ultegra Callipers – having used the Disc RS pads before I knew they’d offer me something more than the standard Shimano L03A (now replaced by the L05A-RF), but I was pleasantly surprised to find that they had even more power than I remembered.

The pads do wear ever so slightly quicker in the wet but they remain quiet. Pad life in general isn’t really a big problem as the reduced 1.6mm backing plate makes space for more pad material and this improves the service life of the pad – at the very least it gives you an extra margin for issues should the weather turn bad during a long ride when you’re away from home.

I’d favour the Disc RS in most instances in comparison to the brand's Exotherm 2 pads reviewed below – the exception to this is when heat control is a factor. They're a good gravel bike upgrade.

Best Value Performance

The Organic pads that BBB produce are great aftermarket alternatives, especially when supply issues restrict the use of the standard OE options. Similar to Aztec, BBB makes a simple range of alternative pads for many of the well known brands. The compound too is similar to what OE brands offer.

I found the initial bite is good, if slightly raspy, and the modulation is almost on par with Shimano and SRAM’s standard options. One nice feature is that the BBB pads come “pre-sanded”, which actually does affect the initial break-in period in a positive way as the pads feel powerful and are quiet straight away.

Most pads are released from a mold and the process, which commonly involves heat leaves a slightly glazed top layer on the pads. Taking this layer off is effectively what we're talking about when we mention "breaking-in" periods on new brake pads - BBB has sped up the process by making the pad slightly thicker and then skimming off the surface to produce a perfectly flat pad that doesn't require bedding in!

BBB also produces a sintered pad. A great option for wet weather training, but probably not to be considered an upgrade.

Best Budget

Whilst not known as a premium brand the Aztec pads punch well above their weight in my opinion. If you’re a rider on a budget or you just want a simple set of pads for winter riding the Aztec Organic option is easily on par with many of the factory (OE specification) brake pads.

These pads are quiet from day one and take very little time to bed in – they are very slightly raspy compared to the Shimano pads. The backing material deals with the heat of braking well and the black coating applied to the steel seems to function in some way as a system for radiating the heat.

This won’t be as effective as fins but it still works well. These pads lack the ultimate power and modulation of the Swissstop options but considering the price, they’re a brilliant no-fuss option for your winter bike or your 2nd bike.

They also offer sintered options for most major brands, but be aware that these cannot be used with all rotors – some of the Shimano rotors for example specify “Resin Pads Only” so do check with the manufacturer before fitting any sintered pad. Aztec make sintered compatible rotors if you need them.

Best for SRAM

Whilst not an upgrade for any other systems, I’ve included the SRAM sintered pads because they’re actually very good and they do offer an upgrade on the standard 'Quiet' organic pads when you use them in the correct conditions. They only produce pads for their own brake systems, but SRAM’s sister company, Avid, has helped make some really good quality pads.

The 'heavy duty' option lasts longer than the standard OE pads and offers more power and bite in wet conditions. This was the only pad on the test which wasn’t tested on my Shimano Ultegra Callipers since it's SRAM-specific, so therefore you could argue that any comparison in performance cannot be verified. But it’s still a relevant real-world test as conditions will have a similar effect on the pads regardless of the brake itself. The SRAM pads definitely didn’t mind a bit of rain, in fact, I’d argue that they seemed to get stronger in wet conditions.

I was surprised to find that the heavy-duty option can suffer a little with glazing over if the brake system gets too hot and this was a bit of an issue in the dry. This left the brake with less modulation and less initial bite – not to a dangerous level but it was definitely noticeable.

I removed the pads and used some sandpaper on the top surface of the braking material and they behaved as new again, which was a simple fix but one that most people may be loath to do. That was the only flaw however and in general, I’d say that they are nearly as good as the Exotherm 2 pads.

SRAM’s organic/'quiet' pad doesn’t seem to suffer from glazing and in most cases is a great pad and a brilliant option for most riders. It does however wear quickly and can suffer from brake fade with heavier riders on long descents.

Best for Shimano

As mentioned above I tested all the pads on the same Shimano Ultegra Callipers which are supplied with the standard Shimano L03A (now replaced by the L05A-RF) pads. To double check my comparisons I tested both the L03A and the newer L05A-RF pads. Could I tell the difference? No, the pad is more of an evolution than an upgraded product, but that’s not necessarily a problem as it was already a very good fit and forget option.

I have found that these pads suffer more than others with contamination. I’m not sure if I’ve just been unlucky but I‘ve binned a few sets over the years which just refused to stop making that terrible squeal! The pad material itself seems very soft which is one of the reasons that they wear quite quickly but also one of the reasons why the initial bite and the modulation are so good.

They do seem to suffer slightly with heat control which is odd given the huge radiators. The new design doesn’t seem to have changed much in real life and as a plain replacement they’re good, but all the other options here provide significant gains in performance or savings on the price, in the case of the Uberbike options both!

Best E-Bike Upgrade

Less well known than many others here but Uberbike is a brand that I first knew about from mountain bike racing – I wasn’t sure what the quality would be like but after a few years of use on various bikes I’ve been really impressed.

Uberbike offers five compounds including one that’s e-bike specific. The sintered and organic offerings are similar to what other brands produce. The Race Matrix version that I tested here uses a medium density pad material to give the best mix of power, bite and service life.

Sounds too good to be true? I was surprised too, but Uberbike really nailed it here. Initially when I set the pads up it was cold and wet, which aren’t ideal conditions to bed the pads in so I did get a little bit of noise initially on that first ride. But very quickly the noise disappeared.

Once they were bedded in the initial bite is fantastic and it just gets better and better. The modulation is very good and only really suffers when you get some serious heat into the brake – probably more to do with the brake rather than the pads.

With this specific compound I’ve experienced a lot less wear than I’ve had with the organic compound that I tested before and also less than the other organic options on this test. I’d say in general that these pads are on par with the Swissstop Disc RS pads which is pretty impressive given the price.

Like the Disc RS these pads feature a slimmed down backing plate which makes space for more pad material and therefore a longer service life. The pads are also safe to use on all rotors unlike some fully sintered pads.

I also tested the all new Kevlar option from Uberbike. I’ve only used these for a month but I’ve been really impressed. They are basically similar to the Organic compound in terms of bite and feel, but they last far longer like the Race Matrix. Interestingly I’ve never had any issues with noise from the Kevlar pads – they work really well in the cold and when riding in the rain! This is definitely an upgrade brand to consider.

Best for Long Descents

The new “Exotherm 2” pads are designed to deal with heat better than the RS pads due to the fins which radiate more heat away from the brake. This isn’t a problem for most short rides, but for those that travel with their bikes to more mountainous places it would definitely be a concern and it’s worth remembering that Shimano’s standard pad is finned for the same reason.

Therefore, for heavier riders or long descents (especially both) where heat control is an issue it makes good sense to consider the Exotherm 2 pad.

In terms of feel, the power and the general modulation is very similar to the RS version. After the initial bedding-in period this got even better. In part this is down to a slightly different pad material - Swissstop are being slightly cagey about precisely what it is, but it’s similar to what many brands would refer to as Sintered (I’ve also heard it called a “hybrid” material).

Interestingly they developed their original pads with the help of the Swiss Railways Engineering department, so I would hazard a guess that the material has been developed with materials from outside the bike industry.

Initial bite improves over time, but the power and the modulation are where you really notice the difference – there’s very little “brake fade”, where the brake’s performance decreases as things heat up. You’ll notice this most towards the end of long descents or if you’re a particularly heavy or aggressive rider.

Everything you need to know about disc brake pads

Brake pads commonly come in various compounds which have both pros and cons based on the weather conditions, bite, overall power and modulation. Even with the standard options available from the groupset manufacturer there is very often an upgrade path available whilst staying on brand.

Most brands produce both “sintered” and “organic” pads. Sintered (sometimes referred to as steel or metal) pads contain small amounts of metal in the pad material itself which are designed to maximise longevity in bad conditions – for this reason the rest of the pad material can be made to create more friction and therefore more stopping power. Organic pads are much quieter and often offer more modulation – they’re excellent for use on the Summer bike.

Pads also are commonly offered in three different backing materials. Steel is the cheapest but it can be heavy – it deals with heat very well. Aluminium is much lighter but it is possible to warp the backing material on very long alpine descents which often causes unwanted noise longterm.

Therefore many brands offer a third option which is an aluminium backer with a built in heatsink – these look a bit like a radiator sitting at the top of the pad and works in the same fashion, radiating heat away from the brake. Don’t confuse backing material with whether a pad is sintered or not as it’s not always obvious.

How We Test

We are riders first and foremost here at Cycling Weekly and we test a very wide range of bikes and components, including many of the best road bikes and best gravel bikes. Most bikes come with disc brakes, so there's ample opportunity to get the feel for different braking systems.

Swapping in new brake pads is a fairly simple process once you understand what you're doing, so it's relatively easy to test a range of different pads as part of our riding.

When we test brake pads, we will focus on three main areas specifically when considering our overall score and verdict. The first of which is always the fitting and initial brake feel through the bedding-in period, this is important as your first impression of a product will inevitably influence your overall view. As the pads bed-in our testers will start to consider overall performance and test the pad's ability to perform in different scenarios. Finally, our parting thoughts will move to the longevity of the pads and if that has any effect on performance as they wear down.

Glossary

• Sintered - often referred to as metal or steel pads, Sintered pads are pads made of a hard material usually metal which allows an increased lifespan. The trade-off is most commonly less performance and a noisier brake.
• Organic - this a much softer brake pad material which most commonly offers much higher braking performance at the cost of decreased longevity and poor heat management.
• Resin - most commonly found in Shimano systems. Shimano combines the benefits of organic pads with harder non-metallic material similar to a sintered pad to increase pad life without increasing noise and heat.
• Semi-metallic - similar to Shimano resin pads, semi-metallic pads include harder materials usually metals to increase pad life while trying to minimise any effects on pad performance.
• Bedding-in - for a brake pad to achieve its optimal performance a number of heating and cooling cycles need to be performed. This process which should be completed before pushing the pad to its limits is called 'bedding-in'.
• Fade - brake fade is common in any brake be it a car or bicycle. It refers to a reduction in the performance of a brake as heat builds up during use. To many, this will feel like when increased pressure at the lever results in no further increase in braking power.
• Modulation - is the ability to control the amount of clamping force on a disc with a given pull of your brake lever. It's useful for scrubbing speed, controlling your bike through turns and keeping your tyres from skidding.
• Bite - to many this will be the feeling of power a brake offers. It's that initial jerk reaction and how hard you need to pull the leave to lock the wheels.
