WHEELS Mfg Cable Housing Ferrule

No, these are specifically designed for 4mm shifting cable housing. Brake housing typically requires a larger 5mm diameter ferrule, so these will not fit correctly.

The flat internal bottom provides a solid stop for the cable housing. This prevents the housing from pushing through the ferrule and into the shifter or derailleur, which helps maintain consistent, crisp shifting performance.

These ferrules are designed to fit standard 4mm shifting housing used by most major manufacturers like Shimano and SRAM. As long as your housing measures 4mm, these should provide a secure, precision fit.

Aluminum ferrules offer superior durability and resistance to deformation under tension compared to plastic alternatives. They provide a more secure connection that won't crack or compress over time, ensuring your cable system stays reliable.

With 50 pieces included, this pack is ideal for professional shops or home mechanics who perform frequent maintenance. It is a cost-effective way to keep a steady supply of high-quality ferrules on hand for multiple bike builds or regular cable replacements.
