74g 88g Super Lightweight Centerlock Disc Brake Rotor | 140mm & 160mm

Super lightweight Centerlock Rotors designed for road disc brakes.

- Upgraded material 7075-T651 Aluminium, a heat-treated alloy with additional stress-relief stretching for improved material stability. This significantly reduces internal stresses, helping prevent warping or distortion during and after machining, especially in thin, lightweight, and heavily machined designs. 

The result is better flatness, tighter tolerances, and more consistent rotor runout, delivering smoother braking performance and long-term reliability compared to standard T6 material.

- Fully CNC bracket to shave every possible bit of weight while maintaining the strength needed for braking

- SUS420 steel disc and rivets to ensure heat management for long and consistent braking

Important note:
HOPE caliper may have smaller clearance for this 160mm rotor.
A flat M5 washer between caliper and flat mount adapter will solve rubbing issue.

Disclaimer

Bicycle and other components in the pictures are not included.

While the rotor braking surface is made of stainless steel, brown spots on the cut-out slot walls may appear due to the high-temperature laser cutting process, which may deposit iron ions. These can be brushed away, are largely cosmetic and don't contact the brake pads.

Rotors are true out of the factory, but in the event they get slightly warped during shipping, here's a guide by Park Tool on How to True a Rotor.
