Continuous Lightweight Design & Premium Finish
The Chaser Sports adapter features a refined, independent structural profile carved entirely from premium 7075-T6 aluminium. Chosen for its exceptional strength-to-weight ratio, this high-grade alloy enables aggressive material pocketing without sacrificing braking rigidity. To ensure a stunning aesthetic that complements high-end groupsets, each piece undergoes a dedicated CNC polishing process after oxidation colouring, resulting in a brilliant, highly reflective surface finish.
