Product Details

Overview & Technology

SRAM GX Eagle Pulley Kit (Model ID: RD-SPP-A0, MPN 11.7518.089.000) is the factory replacement set engineered for GX Eagle rear derailleurs. These pulleys are manufactured to OEM tolerances to preserve shifting precision, minimize drivetrain noise, and maintain the intended geometry of your Eagle drivetrain. The kit uses high-strength, glass-filled polymer pulley wheels paired with low-friction sealed cartridge bearings. That combination keeps rotating mass low while delivering long service life and consistent performance across muddy, dusty, and wet conditions common on mountain trails.

Key Features

Purpose-built for GX Eagle: Exact fit and tooth profile designed to match SRAM's GX Eagle cage spacing, chainline, and derailleur geometry for crisp, accurate shifts. • OEM fit & finish — manufacturer part 11.7518.089.000 / RD-SPP-A0. • Durable materials — glass-filled polymer pulley wheels resist wear and impact while keeping weight down. • Sealed cartridge bearings — reduce friction, repel contamination, and extend service intervals. • Lightweight packaging — shipping dims 3.622" x 2.5984" x 0.5512", weight 0.1 lb.

Fit & Compatibility

This pulley kit is compatible specifically with SRAM GX Eagle rear derailleurs. It’s intended as a direct OEM replacement so no cage or derailleur modification is necessary. Confirm your derailleur model and take note of the SRAM Model ID (RD-SPP-A0) and manufacturer part number (11.7518.089.000) when ordering to ensure correct compatibility. If you run a different Eagle level (NX, X1, X01, XX1) or a third-party long-cage conversion, double-check tooth counts and cage spacing — some non-GX variants use different pulley sizes or profiles. When in doubt, consult product docs or contact our tech team for fit confirmation.

Who It's For

This pulley kit is for mountain riders who want a reliable, OEM-quality replacement for worn or noisy GX Eagle jockey wheels. Ideal for riders maintaining their drivetrain after high-mileage seasons, heavy trail use, or contamination from mud and grit. Also a good choice for mechanics and home wrenchers who prefer factory-spec components for guaranteed shift performance and simple bolt-on replacement without shimming or additional parts.

Frequently Asked Questions

Will this pulley kit fit my SRAM GX Eagle derailleur?

Yes — this is the OEM replacement pulley kit specifically for SRAM GX Eagle derailleurs (Model ID RD-SPP-A0, MPN 11.7518.089.000). Verify your derailleur model before ordering; if you run a non-GX Eagle derailleur or aftermarket long-cage conversion, double-check compatibility.

Do these pulleys come with bearings installed?

Yes. The pulleys use sealed cartridge bearings installed in the polymer wheels. The sealed design reduces maintenance and keeps rotation smooth in muddy or wet conditions.

How difficult is installation and what tools do I need?

Installation is straightforward for anyone comfortable with routine drivetrain work. You’ll typically need a T25 Torx or the relevant wrench for your derailleur’s pulley bolts, threadlocker if recommended by SRAM, and a clean rag. Follow torque specs from SRAM for reassembly.

When should I replace my derailleur pulleys?

Replace pulleys when you notice rough or noisy rotation, visible tooth wear, excess side-play in the wheel, or degraded shifting performance. Many riders replace pulleys every 2,000–5,000 miles depending on conditions and maintenance habits.

Are these pulleys an upgrade over stock?

These are OEM-spec replacement pulleys — designed to restore stock performance rather than upgrade it. For performance upgrades, some riders opt for aftermarket lightweight or ceramic-bearing pulleys, but OEM parts deliver predictable durability and compatibility.

What’s included in the kit?

The kit includes the upper and lower pulley wheels compatible with GX Eagle derailleurs and sealed bearings pre-installed. Small fasteners may be included depending on SRAM’s packaging; check pack contents on delivery and retain the manufacturer part number for reference.

Buying Guide

When buying a pulley kit, prioritize compatibility and bearing type. OEM kits like this SRAM GX Eagle set guarantee the correct tooth profile and cage spacing for your derailleur, ensuring shift quality without adjustments. Check model IDs and part numbers — RD-SPP-A0 and 11.7518.089.000 — to avoid mismatches. Consider your riding conditions when choosing between OEM and aftermarket pulleys. Sealed cartridge bearings in OEM kits strike a balance of low maintenance and durability for most trail riders. If you seek marginal weight savings or ultra-low friction, aftermarket ceramic-bearing options exist, but they may require more frequent servicing and cost more.
