Engineering and braking benefits
The CNC-machined braking surface is designed for flatness and predictable braking, while the SUS420 track adds wear resistance and the aluminum center reduces rotating weight. The reinforced core is specified to withstand instantaneous torque up to 100Nm; testing reported loads up to 130Nm without deformation. Heat-resistance claims reach 500°C, supporting consistent braking on demanding descents.
For comparison, the source lists Shimano MT900 at 88g (140mm) and 108g (160mm), versus 86g and 104g for this Chaser rotor. The product is presented as lab-tested and validated by professional road cyclists, for riders who prioritize lightweight performance, heat dissipation and dependable stopping power.
Before ordering
Confirm your hub uses a center lock interface and select the correct 140mm or 160mm rotor size. A center lock lockring must be sourced separately.
