The RockShox Reverb dropper seatpost utilizes a specific hydraulic hose for its operation. When asking about the "size" of the hose, it generally refers to two key dimensions: its outer diameter and its length.
Understanding Reverb Hose Dimensions
For RockShox Reverb models, the hydraulic hose has a standard outer diameter and is typically supplied in a generous length to accommodate various bicycle frame sizes and routing preferences.
Outer Diameter
The standard outer diameter for a RockShox Reverb hydraulic hose is 5 mm. This specific diameter is crucial for ensuring compatibility with the Reverb's banjo fittings, barb, and olive system, which create a sealed hydraulic connection. Using a hose with an incorrect diameter will prevent a proper seal and lead to system failure.
Standard Length
Replacement hydraulic hose kits for the RockShox Reverb commonly include a hose that is 2000 mm long. This extended length is provided to allow riders and mechanics to cut the hose precisely to the required length for their specific bike frame and internal or external cable routing. It ensures there's ample length for even the largest frames or most complex routing paths, with any excess being trimmed during installation.
Key Specifications Summary
Here’s a quick overview of the RockShox Reverb hydraulic hose specifications:
| Dimension | Specification | Purpose |
|---|---|---|
| Outer Diameter | 5 mm | Ensures compatibility with Reverb fittings and seals. |
| Standard Length | 2000 mm | Allows custom cutting to fit various bike setups. |
Why Specific Hose Type Matters
The RockShox Reverb system operates hydraulically, using a specific 2.5wt Reverb hydraulic fluid. The hose is designed to withstand the internal pressures generated during operation and maintain the integrity of the closed hydraulic system. It's essential to use genuine or high-quality compatible hydraulic hose designed for bicycle braking/dropper systems to ensure reliable performance and safety.
Installation and Maintenance Tips
- Precise Cutting: Always use a sharp, dedicated hose cutter to ensure a clean, perpendicular cut, which is vital for proper barb and olive seating.
- Correct Routing: Route the hose carefully through your bike frame, avoiding sharp bends that could kink the hose or impede fluid flow.
- Bleeding: After cutting and installing a new hose, the Reverb system will require a thorough bleed using the RockShox Reverb bleed kit and fluid to remove any air and ensure proper function.
