Miles Racing Disc Brake Pads - Shimano GRX, Ultegra, Dura-Ace, 105 - Semi-Metallic
Pad Type: Semi-Metallic
Give your Shimano XTR, Tiagra, 105, Ultegra, Dura-Ace, or GRX system a refresh with new brake pads. Available in a semi-metallic compound, these brake pads offer a blend of durability and strong braking power so whether you’re in the heat of a cyclocross race or out for a weekend group ride, you’ll be able to count on your brakes when you need them.
These brake pads are a direct replacement for a number of flat mount Shimano systems, including:
- Shimano Deore XT M8100 Series
- Shimano SLX M7100 Series
- Shimano Dura-Ace R9150 Series
- Shimano Ultegra R8050 Series
- Shimano 105 R7000 Series
- Shimano Tiagra 4700 Series
- Shimano Metrea U5000 Series
- Shimano GRX 11-speed
- Shimano GRX 10-speed
Each set includes pads and a spring to replace the brake pads on one caliper.
Different Types of Disc Brake Pad Compounds
Typically you'll find that there are three types of compounds to choose from when buying new brake pads for your disc brake equipped bike. They are:
Each of these brake pad compounds will provide a different feel during braking. You'll also find that one compound may last longer compared than another depending on the type of rider you are and the amount to which you use your brakes.
What compound should I choose?
Choosing a compound ultimately depends on the type of riding you are doing. In most cases a semi-metallic pad will exceed the needs of most riders because it combines the durability of sintered with the feel of organic compounds. To make sure you're getting the best pad for your riding style, review the benefits of each below.
Organic Brake Pads
Organic disc brake pads are made completely of resin and are a much softer compound than a semi-metallic or sintered pad. This softer material means they have a much stronger initial bite and can be easily modulated depending on how much power you need. However, the softer material also means they heat up much faster than a pad with metallic compounds added, so they can fade on steeper or longer descents where a lot of braking is required.
Besides how they feel, another benefit to organic pads is that they break in quickly. Once installing them into the caliper, it only takes a few moments to have the pads feeling strong and ready to go. Semi-metallic, and especially sintered, take much longer to bed in.
|ORGANIC PAD PROS||ORGANIC PAD CONS|
|- Strong initial bite||- Faster wearing|
|- Easy to modulate||- Prone to fade under intense braking|
|- Quietest||- Not ideal for adverse conditions (wet, mud, etc.)|
Semi-Metallic Brake Pads
Semi-metallic brake pads are an all-round solution for most common conditions, where brakes are not getting extremely hot. They work best for dirt jumping, cross country and lighter enduro rides with shorter downhill segments. They'll even be more than capable for downhill riders who aren't standing on the brakes all the way down, or for lighter riders.
With a high percentage of iron and copper added to the resin in the compound, semi-metallic pads offer a longer life and more heat resistance compared to organic disc brake pads. The metal compounds add longevity and the resin allows for the pad to have high friction against the brake rotor right away.
Because of this, you'll notice semi-metallic brake pads have a stronger initial bite when you begin to pull the brake lever. If you prefer your brakes to grab and feel strong from the start, semi-metallic pads should be your first choice.
|SEMI-METALLIC PAD PROS||SEMI-METALLIC PAD CONS|
|- Great initial bite||- Wears faster than sintered|
|- Easy to break-in||- Not ideal for adverse conditions (wet, mud, etc.)|
Sintered Brake Pads
Sintered pads, also known as metal or metallics, are brake pads that are completely made up of hardened metal, bonded together with high heat and pressure. There are no resins present in sintered brake pads making them much more durable than a semi-metallic or organic pad.
Sintered disc brake pads are perfect for larger riders, braking on steeper descents, or riders who have had to deal with brake fade issues. While the initial bite of sintered brake pads are not as strong as semi-metallic or organic compounds, they can handle way more heat.
Sintered brake pads also provide a more consistent feel and can be easily modulated, giving your brakes a progressive feel at the lever, rather than only being on or off.
Sintered pads also shine across a wider range of conditions. They are less likely to be effected by dust, mud, or water than other pad types.
|SINTERED PAD PROS||SINTERED PAD CONS|
|- Longer lifespan||- Longer break-in period|
|- Work better in all conditions||- Lower initial bite|
|- Fade at higher temperatures|
