III-PRO A2 Center Lock disc brake

The III-PRO A2 is a versatile Center Lock brake disc that performs as well on a road or gravel bike as it does on a mountain bike or an e-bike. Its SUS410 stainless steel rotor resists wear and corrosion, and its aluminium alloy lockring keeps the weight down. The laser-cut edges and the hollow structure dissipate heat: braking stays stable after repeated hard braking.

Key Points

SUS410 stainless steel: the rotor resists wear and corrosion, braking stays consistent in the rain and in muddy conditions.

Center Lock mounting: the disc sits on the hub and tightens with the splined lockring, the tool is the same as for a cassette.

Laser-cut hollow structure: heat dissipates faster, performance holds up on long descents.

117 g per disc: less weight on the wheel, steering and accelerations feel more direct.

Compatibility

Center Lock standard: the disc mounts on every Center Lock hub on the market (Shimano, DT Swiss, Hope, Industry Nine, Novatec). 160 mm for road, gravel and XC mountain biking; 180 mm for mountain biking and e-bikes, for more braking power.

Check that your hub is Center Lock and the diameter your caliper or adapter accepts before ordering. A question about compatibility? Write to us.
