WHEELS Mfg Cable Housing Ferrule

Yes, these are designed to fit most standard brake cable housings. With an inside diameter of 5mm, they are specifically sized for the thicker housing typically used in braking systems, rather than the 4mm housing used for shifting.

Brass is significantly more durable and resistant to the high-tension forces applied during braking. Unlike plastic, which can crack or deform under pressure, these precision-machined brass ferrules maintain their shape to ensure consistent cable performance.

The flat internal bottom acts as a stop for the cable housing, preventing it from pushing through the ferrule and into the brake lever or caliper mechanism. This creates a secure, reliable connection that helps maintain responsive braking feel.

No, these are not suitable for derailleur cables. Derailleur housing typically requires a 4mm ferrule, and these are sized at 5mm for brake housing. Using the wrong size will result in a loose, sloppy fit that compromises your shifting accuracy.

This 50-count bulk pack is ideal for both. It provides a cost-effective solution for professional shops managing high-volume repairs, while also serving as a lifetime supply for a dedicated home mechanic who maintains multiple bikes.
