Why It Is so Important to Find the Right SRAM Disc Brake Rotors
The German development department in Schweinfurt also knows that the brake rotor must be an exact match for the area of use, the system weight and the brake system on your bike. After all, you can only achieve optimum braking performance if the shape and diameter, mounting standard and material are matched. Specifically, you have the following advantages with the right SRAM rotor:
- Better heat dissipation: For consistent braking performance and less fading
- Weight saving: High-quality rotors from SRAM save valuable grams of rotating mass thanks to the aluminium spider
Adaptation to rider weight and area of use: Larger rotors provide better braking power and heat dissipation. Smaller rotors save weight and can be adjusted more precisely.
These SRAM Brake Rotors Are Available
SRAM offers a well-thought-out selection of brake rotors that are perfectly matched to different disciplines and requirements – from lightweight road bikes to robust gravity bikes. The Centerline and Centerline X models form the solid basis for cross-country, trail and endurance road bikes. They are characterized by low weight and consistent braking performance – ideal for riders who rely on proven function.
The Paceline and Centerline XR rotors are even lighter and optimized for maximum smoothness. Thanks to their two-piece construction with aluminium carriers, they effectively reduce vibrations and are suitable for particularly high-quality road bikes and gravel bikes with Rival, Force and Red AXS components.
Those who need maximum strength, on the other hand, should opt for the HS2 – SRAM's brake rotor for aggressive MTB use and electric bikes. With a reinforced design, a thickness of 2.0 mm and special milling for heat dissipation, it provides noticeably more braking power and thermal stability on long descents.
These Technical Details Are Decisive for Your Decision
The technical differences lie in the details: The choice of diameters ranges from 140 mm to 220 mm – larger rotors provide more braking power, but also require compatible frames, forks and corresponding SRAM brake adapters. Disc thickness also plays a role: While standard models work with 1.85 mm, the 2.00 mm thick HS2 requires a suitable brake caliper. With the exception of the HS2 , you can choose between one-piece versions for minimum weight and two-piece X and XR models with aluminum spider for better cooling and higher torsional rigidity. Safety is also taken into account: Some models are equipped with rounded edges (“Round Edges”) in accordance with UCI specifications – this makes handling easier and increases safety in a competitive environment. For mounting, you should pay close attention to the hub standard of your bike: SRAM offers both 6-hole and Center Lock versions. If necessary, you can use suitable adapters to ensure maximum compatibility.
Things to Consider Before Buying SRAM Brake Discs
If you want to buy new rotors for your SRAM disc brakes or disc brakes from another manufacturer, we have the following tips for you:
- Diameter: You must always make sure that the diameter matches the brake system. If you want to fit a larger or smaller disc, you need to fit an appropriate adapter to attach the brake body – and make sure you check which diameters are approved for your bike and fork.
- Thickness : The disc thickness must be compatible with the brake caliper.
- Brake pads: If you want to change the performance and heat resistance, you must always think about the brake pads. Organic pads work more quietly, but offer slightly less power and wear out more quickly. Sintered pads offer greater braking power and longer durability – especially in wet conditions.
- Fastening: 6-hole SRAM brake rotors are supplied with Torx fastening screws. For Centerlock SRAM rotors, you must order a lockring separately.
Tip: You will need the right special tool to mount your brake rotor – a Torx T25 wrench for 6-bolt rotors and a cassette puller or BSA wrench for Center Lock rotors.
Select SRAM Rotors to Suit Your Brakes and Application
If you want to buy a SRAM drivetrain or disc brake for your bike set-up, you must select the SRAM rotors separately in the appropriate diameter.
