Chaser 6-Ultra G2 Center Lock Disc Rotor for Road / Gravel

TiWorks Partner Select: supplied through our cooperation with Chaser, this 6-Ultra G2 Center Lock rotor complements TiWorks titanium brake hardware and premium road / gravel disc-brake builds.

Designed for road and gravel center lock wheelsets, the 6-Ultra G2 rotor uses an optimized 7075-T6 alloy carrier with a heat-treated SUS420 stainless steel braking track. Compared with the previous generation, the supplier notes a larger braking surface, improved torsional strength, and an updated carrier structure using hollow titanium rivets.

- For stronger braking performance, the supplier recommends metallic pads such as Shimano L04C-type pads
- Confirm rotor size, caliper clearance, frame / fork specification, and brake pad compatibility before ordering.
