Brake Rotors

Maximise Your Stopping Power with Mountain Bike Brake Rotors

Brake rotors play a crucial role in your mountain bike's braking system, providing the stopping power and control needed to navigate challenging trails. At Cranxs, we connect you with a wide range of sellers across the UK offering new and used brake rotors. Whether you’re upgrading for better performance or replacing worn-out parts, our marketplace has the ideal rotors to enhance your ride.

Types of Mountain Bike Brake Rotors

Standard Rotors

• Versatility and Performance: Standard rotors offer reliable performance and are suitable for most riding styles. Available in various sizes, they provide a balance of stopping power and weight.
• Common Sizes: Standard rotor sizes include 160mm, 180mm, and 203mm, allowing you to choose the best fit for your riding needs.

Floating Rotors

• Heat Dissipation: Floating rotors feature a two-piece design with a steel braking surface and an aluminium carrier, which helps dissipate heat more effectively. This design reduces the risk of brake fade during long descents.
• Enhanced Durability: The floating design also allows for slight movement between the braking surface and carrier, reducing the risk of warping.

Benefits of Upgrading Your Brake Rotors

Improved Braking Performance

Upgrading to high-quality brake rotors can significantly enhance your bike's stopping power and modulation, allowing for precise control on technical trails and steep descents.

Better Heat Management

Advanced rotors, such as floating designs, offer superior heat dissipation, reducing the risk of brake fade and ensuring consistent performance during long rides.

Increased Durability

Durable rotors made from high-quality materials last longer and withstand the rigours of aggressive riding, providing reliable braking power over time.

Choosing the Right Brake Rotors

Match Your Riding Style

• Cross-Country Riders: Opt for lighter, smaller rotors (160mm) that offer sufficient stopping power without adding unnecessary weight.
• Trail and Enduro Riders: Choose larger rotors (180mm or 203mm) that provide greater stopping power and better heat management for aggressive riding.

Check Compatibility

Ensure the rotors you choose are compatible with your bike's braking system and mounting type. Verify the rotor size and bolt pattern to avoid fitment issues.

Maintenance Tips for Brake Rotors

Regular Inspection

Inspect your brake rotors regularly for signs of wear, such as scoring, warping, or thinning. Replace rotors that show significant wear to maintain optimal braking performance.

Proper Cleaning

Keep your rotors clean from dirt and grime to ensure consistent braking power. Use a suitable brake cleaner and a clean cloth to wipe down the rotors after rides.

Check for True

Ensure your rotors are true and free from warping. A warped rotor can cause uneven braking and reduce performance. Use a rotor truing tool to correct minor warps or replace severely warped rotors.

FAQs About Mountain Bike Brake Rotors

How often should I replace my brake rotors?

The frequency of replacement depends on your riding style and conditions. Generally, replace your rotors if they become significantly worn, warped, or if the braking surface is less than 1.5mm thick.

Can I upgrade to larger rotors?

Yes, upgrading to larger rotors can enhance stopping power and heat dissipation. Ensure your bike's frame and fork can accommodate the larger size, and you may need adapters for proper fitment.

What are the advantages of floating rotors?

Floating rotors offer better heat dissipation and reduced risk of warping, making them ideal for aggressive riding and long descents. They provide consistent braking performance under demanding conditions.
