Product Details

Overview & Technology

Precision OEM replacement for your Lyrik D1 fork. This RockShox lower leg in Gloss Black (Mfr. Part # 11.4018.091.076, SRAM Model ID FS-SPP-A0) is manufactured to the same tolerances and finishes as the originals, designed specifically for 29" Lyrik Ultimate D1+ and Lyrik Flight Attendant forks (2023+). The lower leg is crafted from high-strength forged aluminum with a hard anodized internal finish to resist abrasion and corrosion. The exterior glossy paint resists chips and is supplied with matching foil decals. Built-in PRV (pressure relief valves) locations and boss geometry maintain factory serviceability and damping integrity for consistent on-trail performance.

Key Features

Factory-correct construction and details. These lowers include the correct bossing, internal channels and mounting points for damper hardware, axle standards and brake caliper alignment used on the 2023+ Lyrik D1 platforms. • Material: Forged 6000-series aluminum for strength-to-weight balance. • Finish: Gloss Black paint with foil decals included. • Axle & Wheel: 15x110 Boost spacing, 29" specific arch geometry. • Valves: PRV (pressure relief valve) compatible ports and routing. All machining and hole patterning match OEM specs so service parts like seals, bushings and brake adapters fit without modification.

Fit, Compatibility & Installation

This lower leg is compatible with RockShox Lyrik Ultimate D1+ and Lyrik Flight Attendant forks (model year 2023 and later) built around the D1 chassis. Confirm your fork's SRAM Model ID (FS-SPP-A0) and internal part numbers before ordering. It accepts a 15x110 Boost thru-axle and is optimized for 29" wheel clearance. Installation requires basic fork service skills: removal of the dust wipers and lowers, transfer of seals, bushings and any hardware from the donor leg (or installation of new service kits), and proper torqueing of axle and brake hardware. Use factory service manual torque specs and fresh suspension grease or recommended lubricants during reassembly.

Who It's For

This part is aimed at riders who need a direct OEM replacement after damage, wear, or who want to refresh the look of their fork with a gloss black finish. Enduro and aggressive trail riders who push forks hard will appreciate the factory-fit durability and exact geometry retention. Also ideal for mechanics and shops doing fork builds or refurbishments — the lower leg restores structural integrity and ensures compatibility with stock dampers, air springs and service parts for the D1 Lyrik platform.

Frequently Asked Questions

Will this lower leg fit my Lyrik fork?

This lower leg fits Lyrik Ultimate D1+ and Lyrik Flight Attendant forks from 2023 onward that use the D1 chassis and 29" wheel specification. Verify your fork's SRAM Model ID (FS-SPP-A0) or consult the factory part number 11.4018.091.076 to ensure compatibility.

Are the foil decals included with the lower leg?

Yes — the part ships with the matching foil decals included so you can restore the original factory appearance when installed.

Do I need special tools to install this lower leg?

Basic suspension service tools are needed: a torque wrench, seal drivers, snap ring pliers, and appropriate hex/torx sockets. If you’re not experienced with fork service, we recommend having a qualified shop perform the replacement to ensure correct seal/bushing seating and torque values.

Can I reuse the seals and bushings from my existing lowers?

You can transfer seals and bushings if they are in good condition, but RockShox and most technicians recommend installing new service kit components when replacing lowers to guarantee optimal performance and longevity.

Is this an OEM RockShox part or an aftermarket copy?

This is a genuine RockShox OEM lower leg (Manufacturer Part # 11.4018.091.076) manufactured to factory tolerances and supplied with the correct decals and bossing for professional fitment.

Does this lower leg include axle or brake hardware?

No — this item is the lower leg only. Thru-axle, brake caliper bolts and internal damping hardware are not included and should be transferred from your original parts or purchased separately.

Buying Guide

When replacing fork lowers, prioritize OEM parts that preserve original geometry and mounting points. Choose a lower leg that matches your model year, wheel size and axle standard; mismatched lowers can affect brake alignment and wheel tracking. Consider buying a service kit at the same time to replace seals, bushings and foam rings for a proper rebuild. Check the SRAM Model ID and factory part number before ordering, and decide whether you’ll perform the swap yourself or book a shop service. A professional install paired with fresh consumables ensures the fork returns to its designed performance and reliability.
