ZRACE Z2 Center Lock Disc Rotor Design And Heat Management
This floating rotor design absorbs shock and vibration that rigid rotors cannot handle, extending rotor life and reducing pad wear dramatically. The superior heat dissipation system channels thermal energy away from brake fluid and pad contact surfaces, maintaining consistent braking feel through repetitive descents. CNC precision engineering ensures perfect concentricity with your hub, eliminating brake rub and drag that waste energy on climbs. The center lock mounting interface works seamlessly with both mountain and road disc brake systems across all major groupsets. Stainless steel construction resists corrosion in wet conditions while delivering braking performance that matches premium-tier components at a fraction of the cost.

Absolutely poor workmanship with uneven height and side slippage. Cannot be used without causing wear in the Shimano Ultegra brake caliper.
Unfortunately, I can’t upload a video here.
The manufacturer/dealer ZRACE refuses exchanges and replacements and has extremely poor customer service…never again! !

Hopefully, these ones this time are without the height and side slants like my green ones. That was really a disappointment.
AliExpress Shopper –
Hopefully better than the same ones in green. Those had high-side and low-side crashes and were therefore completely unusable.

Good and affordable. I used them as a replacement for Ultegra brake discs. But I already had some with high deflection and side deflection. Final inspection?

A bit thicker than the Z1 but with more braking surface and a wear indicator. I also really like their appearance and have 7 pairs of them.
