## Questions & Answers

**Q: Is this one rotor or both rotors for front and rear wheels?**
A: This is only one rotor that can be used for either front or rear

**Q: is this a floating rotor or static>?**
A: It’s static, a threaded lock ring holds it to the hub.

**Q: Is the lockring internal or external teeth? Asking for front fork clearance concerns.**
A: The supplied lock ring has internal teeth that fit the cassette lock ring tool. Some through axle wheels will require a different lock ring with external teeth because the stock tool won’t fit. Either one will work with any disc brake fork.

**Q: will this work with a Shimano 105 caliper?**
A: I believe all rotors work with all calipers, however you have to make sure your frame is set up for 140 mm rotor. If not, you need to buy the proper adapter to fit the caliper on your frame to accept the rotor. Also, you need to make sure your wheel hub is set to accept center lock and not 6 bolt. Again, you can buy adapters for this.
