Seriously light weight disc rotor, but has a few features that set it apart from other lightweight rotors:
- 2.0mm thick;
- no pulsing, although a very open design;
- surprisingly low pad weigh, largely due to chamfered edges on each of the cut-outs;
- 140mm rotor weighs 61g (claimed 62g);
- great value for money at around $23 delivered. Check out KCNC Razor rotors on Amazon.
