Product Details

Overview & Technology

RockShox Reverb B1 200hr Kit v2 (Mfg Part # 11.6818.051.007, SRAM ID SP-SVC-T-A1) is the OEM service kit designed to refresh the internal seals and foam components of your Reverb B1 or Reverb Stealth B1 (2017–2019). This compact kit targets the wear items that degrade after regular use and time — the foam ring, inner sealhead bushing and a set of precision O‑rings — restoring the post's hydraulic integrity and smooth stroke action. The components are made to RockShox's material and dimension specs for a direct fit, using resilient elastomers and machined bushings that resist compression set and fluid attack. Replacing these parts on the recommended 200‑hour / 1‑year interval keeps travel damped correctly and helps prevent shaft wear and slow return or external leaks.

Key Features & Benefits

What’s included: foam ring, inner sealhead bushing and replacement O‑rings — the core consumables that commonly fail first in hydraulic dropper posts. These parts are engineered to meet the tight tolerances of the Reverb B1 family for consistent sealing and long life. Real-world benefits: swapping these components eliminates play and spongy feel, prevents oil seepage onto your post and saddle, and restores crisp remote actuation. Using OEM parts avoids fitment issues and ensures compatibility with factory service procedures.

Fit, Compatibility & What’s Included

This kit fits RockShox Reverb B1 and Reverb Stealth B1 models from 2017 to 2019. Manufacturer part number 11.6818.051.007 corresponds to SRAM service ID SP-SVC-T-A1. It’s specifically intended for the B1 series internals — it is not a universal dropper kit and should not be used for older or newer Reverb A/Gen2/Gen3 variants without confirming compatibility. The kit ships as a small pack (10" x 5" x 1", 0.325 lb) containing the foam ring, sealhead bushing and O‑rings only. It does not include hydraulic fluid, remote parts, or tools. Follow RockShox/SRAM service instructions for proper installation, lubrication and any required bleeding procedures.

Who It’s For

This service kit is for mountain bikers and mechanics who want to maintain peak performance from a Reverb B1 dropper post without replacing the entire unit. It’s ideal for home wrenchers who perform routine maintenance and shops that run scheduled service intervals. If you ride regularly in wet or muddy conditions, bikepack long tours, or put heavy hours on the trail each week, replacing these wear items every 200 hours or annually will extend the life of your post and keep your saddle height reliable on technical descents and climbs.

Frequently Asked Questions

How often should I service my Reverb B1 with this kit?

RockShox recommends a 200‑hour or 1‑year interval for replacing foam rings and seals on the Reverb B1. If you ride in very muddy or wet conditions, check the post more frequently and service sooner if you notice sluggish action or leaks.

Can I install the 200hr kit at home or do I need a shop?

A competent home mechanic can fit these parts if they have basic tools and follow RockShox/SRAM service instructions. However, because the post interfaces with hydraulic systems, shops or experienced techs are recommended if you’re uncomfortable with disassembly or any bleed/pressure steps.

Does this kit include hydraulic fluid or remote parts?

No — the 200hr kit includes only the foam ring, inner sealhead bushing and O‑rings. It does not include hydraulic fluid, remote levers, or external components. If a full bleed or remote service is required, order the appropriate bleed kit and fluid per SRAM/RockShox recommendations.

Will this kit fit other Reverb models?

This kit is intended for Reverb B1 and Reverb Stealth B1 models from 2017–2019. It is not guaranteed to fit other Reverb generations (A, Gen2, Gen3) — always confirm compatibility with your post’s model year and service manual before purchasing.

What tools should I have on hand to install the kit?

You’ll typically need basic hex wrenches, a torque wrench for clamp hardware, a clean shop rag, isopropyl alcohol for cleaning seal surfaces, and small picks for seal removal. If any hydraulic lines are disturbed, have the correct bleed kit and SRAM‑approved fluid ready and follow the official bleed procedure.

How can I tell if my dropper needs these replacement parts?

Common signs include slow or inconsistent post return, oil seepage around the stanchion, increased friction or lateral play, and a squishy remote feel. If you observe these symptoms, a 200hr service kit replacement is a logical first step before more invasive repairs.

Buying Guide

When buying a dropper post service kit, match the part number and model year — OEM kits like this Reverb B1 200hr Kit v2 are sized and formulated to the original tolerances. Check your post’s serial/model markings or consult your bike shop to be certain you have the correct variant before ordering. Consider whether you’ll perform the work yourself or hand it to a mechanic: if you’re not comfortable with hydraulic systems or remote bleeds, budget for shop labor. Also buy a bleed kit and SRAM‑approved fluid if you anticipate opening the hydraulic circuit during service.
