🛡️ Core Benefits

Maximum Protection

Bearing longevity. Safeguards expensive hub internals against grit ingress.
Grease containment. Stops essential lubricant throwing onto your tyre rims.
Marine ready. Zinc coat defends against rust caused by road salt and moisture.

Seamless Installation

Precise engineering. Designed for a clean, tight press-fit directly into the hub bore.
Universal utility. Standard dimension matching trusted brands like AL-KO, Manutec, and Trojan.

⚠️ Installation Pointer

To confirm this is the exact size you need, use a digital caliper to measure the internal diameter of your hub’s front hole. A proper 45.2mm hub cap should require a gentle tap with a soft-faced mallet or block of wood to nest securely.
