MTB Bike Shifter Cable Housing Inner Hose Material PE POM PTFE

Bike shift housing, also known as gear cable housing or shifter cable housing, is a type of outer casing used specifically for the shifting or gear control cables on bicycles. It encloses and protects the inner shift cables, allowing for smooth and precise shifting of gears.

Here are some key aspects of bike shift housing:

1. Material: Bike shift housing is typically made from reinforced plastic or polymer materials. These materials provide durability, flexibility, and resistance to the elements.

2. Diameter: The diameter of bike shift housing can vary depending on the specific bike and the type of shifting system being used. Common sizes range from 4mm to 5mm, although larger or smaller diameters may be used for certain applications.

3. Construction: Bike shift housing is often constructed with multiple layers for added strength and protection. The innermost layer may have a low-friction lining, such as Teflon or a similar material, to reduce friction and ensure smooth cable movement. The outer layers provide structural support and resistance to moisture, dirt, and abrasion.

4. Compressionless Design: Bike shift housing is typically designed as compressionless housing to ensure precise and immediate shifting response. Compressionless housing maintains its shape when compressed, allowing for consistent and reliable shifting performance.

5. End Fittings: Bike shift housing is equipped with end fittings or terminations designed to securely attach to the shifters and derailleurs. These fittings ensure proper connection, prevent fraying or unraveling of the housing, and allow for easy installation and adjustment.

Proper installation and maintenance of bike shift housing are important for optimal shifting performance. This includes securely attaching and routing the housing, inspecting for signs of wear or damage, and lubricating the shift cables as needed.

It's important to note that specific requirements and specifications for bike shift housing can vary depending on the bicycle manufacturer, the type of shifting system being used (e.g., mechanical or electronic), and the specific model of the bike. Therefore, it is recommended to consult the bicycle manufacturer's guidelines or seek advice from a professional in bike maintenance for accurate information regarding the appropriate shift housing for your specific bike.
