Frequently Asked Questions (FAQ)
Here are some common questions about mountain bike brake rotors:
Q: What size rotor should I get?
A: It depends on your riding style and the terrain. Bigger rotors provide more stopping power. They are good for downhill. Smaller rotors are lighter and good for cross-country.
Q: What is the difference between six-bolt and Center Lock?
A: Six-bolt rotors attach with six bolts. Center Lock rotors attach with a lockring. Make sure your hub is compatible.
Q: How do I know if my rotor is worn out?
A: Check the rotor’s thickness with a caliper. Most rotors have a minimum thickness marked on them. If it’s below the minimum, replace it.
Q: Can I use different size rotors on the front and rear?
A: Yes, you can. Many riders use a bigger rotor in the front. The front brake does most of the stopping.
