K-Tech 40 spokes 21" inox mini drum hub

Mini front drum brake for custom bikes. Features an 80mm wide chrome plated cast iron drum. The cooling fins on the drum help to dissipate heat and yield a nostalgic look. Drum has an internal diameter of 130 mm, whereas the side covers are made from aluminum with a polished finish. Comes with bearings for use on 3/4" wheel axles installed. Special spokes for use with 40-hole 21" rims, and anchor brackets are separately available.
Note: Due to its small size the braking power will only be sufficient for lightweight and stripped bikes.
