Product Details

Overview & Technology

RockShox Reverb Hydraulic Fluid is the factory-specified hydraulic oil for SRAM Reverb dropper seatposts. Offered in a 120 ml bottle (part number 11.4315.021.070, product #900948) and a 1L service pack, this fluid is formulated to the SRAM Model ID SS-OIL-RVB-A1 specification for consistent performance. The fluid is a 2.5wt oil engineered to reduce foaming, stabilize damping and protect internal seals and o-rings across a wide temperature range. Using the correct oil helps preserve smooth, predictable post movement, extends component life and avoids seal-swelling or accelerated wear caused by incompatible fluids.

Key Features

Precision formulation: 2.5wt viscosity tuned for Reverb internals — balances lubrication and hydraulic responsiveness for consistent dropper operation. OEM compatibility: Meets SRAM Model ID SS-OIL-RVB-A1, ensuring flushing, bleeding and long-term performance match factory service expectations. Available as a single 120 ml service bottle and a 1L workshop pack for frequent maintenance.

Fit & Compatibility

This fluid is specifically designed for SRAM/RockShox Reverb hydraulic dropper posts. The 120 ml bottle is the OEM-sized refill for most single-post bleeds and basic services; the 1L option is aimed at shops or technicians performing frequent maintenance. Do not mix with other hydraulic fluids or brake fluids. Mixing incompatible fluids can damage seals and void warranties. Always follow SRAM/RockShox service procedures and use clean tools and syringes when bleeding the system.

Who It's For

Home mechanics and trailside tuners who want OEM-level performance for their Reverb dropper post will appreciate this ready-to-use 120 ml bottle. It's compact, easy to store and sized to perform a full bleed on most Reverb models. Bike shops and frequent-service riders should consider the 1L variant to reduce waste and lower per-service cost. Anyone who wants to preserve smooth actuation and extend seatpost life should use the correct RockShox Reverb fluid rather than third-party substitutes.

Frequently Asked Questions

Is this fluid compatible with all Reverb models?

Yes. This RockShox Reverb hydraulic fluid meets SRAM Model ID SS-OIL-RVB-A1 and is intended for use across SRAM/RockShox Reverb dropper posts. Check your post's service manual for specific bleed procedures and recommended volumes.

How much fluid do I need for a full bleed?

The 120 ml bottle is sized for most single-post bleeds and basic services. Some older or heavily contaminated posts may require slightly more fluid — if you perform frequent shop work, opt for the 1L variant to ensure you always have enough.

Can I mix this with other hydraulic oils or brake fluids?

No. Do not mix Reverb hydraulic fluid with other hydraulic oils, DOT brake fluids or mineral oil. Mixing can cause seal swelling, loss of performance and may void your component warranty.

How often should I change or top up the fluid?

Service intervals depend on use and conditions. As a general guideline, inspect and service your Reverb post annually or sooner if you experience spongy action, air in the system or inconsistent movement. Heavy riding, mud and heat can shorten intervals.

Can I bleed the Reverb myself with this bottle?

Yes. The 120 ml bottle supplies OEM fluid for at-home bleeds when used with the correct bleed kit and tools. Follow SRAM/RockShox instructions carefully: maintain cleanliness, use the proper syringes, and purge air thoroughly for reliable results.

Buying Guide

When buying hydraulic fluid for your Reverb seatpost, choose the OEM-specified RockShox Reverb fluid to match viscosity and seal compatibility. For occasional maintenance, the 120 ml bottle is convenient and sized to complete a single service; choose the 1L option if you run a shop or service multiple posts. Always confirm your post model and follow the SRAM/RockShox bleed procedure. Investing in the correct fluid and a proper bleed kit prevents costly damage and keeps your dropper operating smoothly on the trail.
