Shimano SM-BH90 Connecting Bolt Unit

The Shimano SM-BH90 Connecting Bolt Unit is a key component used in Shimano hydraulic brake systems, specifically designed for connecting the brake hose to the lever. It is typically used with SM-BH90 brake hoses.

Key Features

1. Compatibility: The SM-BH90 connecting bolt is designed to work with Shimano hydraulic hoses like the BH90, which are used in higher-end models due to their narrower diameter and stiffer structure, providing more direct and powerful braking performance.

2. Hose Connection: This connecting bolt unit secures the hydraulic hose to the brake lever. It’s usually paired with an olive and insert (aka barb) to ensure a tight and secure hydraulic connection.

3. Material: Typically made of high-quality steel or other durable materials to withstand the pressure from hydraulic fluid over time, while maintaining a leak-free connection.

Installation Notes:

• Make sure to use the correct olive and insert (barb) for the SM-BH90 hose.
• Properly cutting and preparing the hose end is essential to ensure a tight, leak-free connection.
• Its also recommended to use Shimanos mineral oil for these hydraulic systems, as other brake fluids like DOT fluid are not compatible.
