Product Details

Overview & Technology

SRAM GX DH Pulley Kit (Model RD-SPP-A0, MPN 11.7518.070.000) is the factory replacement pulley set for GX DH 7-speed rear derailleurs. This compact kit contains the upper and lower jockey wheels and the hardware sized specifically for SRAM's GX DH 7-speed cage, restoring the intended chain path and shift feel after wear or damage. Built for gravity — the pulleys are engineered to survive the impacts, mud and continuous high-load shifts typical of downhill and enduro riding. The design focuses on durable materials, precise bearing support and correct tooth profiles to keep chain noise low and shifting consistent under extreme conditions.

Key Features & Real‑World Benefits

Sealed bearing construction reduces contamination from mud and water, prolonging service intervals and keeping shifts crisp when the trails get sloppy. Riders will notice reduced side-to-side play and more positive engagement under load versus worn pulleys. OEM fit and hardware means a direct swap — no modification required. Lightweight pulley wheels and purpose-matched bolts restore factory chainline and reduce drag, translating to quieter coasting and more reliable gear selection on steep, technical descents.

Fit & Compatibility

This kit is specifically compatible with SRAM GX DH 7-speed rear derailleurs. Confirm your derailleur model and speed: the kit matches the GX DH 7-speed cage geometry and sprocket spacing; it is not compatible with SRAM 9/10/11/12-speed or Eagle systems without the matching cage. Manufacturer details: Product Number 271043, Manufacturer Part # 11.7518.070.000, SRAM Model ID RD-SPP-A0. Shipping dimensions: 3.75" x 1" x 5.5", Weight: 0.1 lb. Always check cage length and chainline when ordering replacement pulleys to ensure correct fit.

Who It's For

This pulley kit is aimed at gravity-focused riders — downhill and enduro racers, shuttle riders and trail mechanics who need an OEM replacement that matches original SRAM performance. If you ride aggressively, frequently expose your drivetrain to mud or crash your back wheel, fresh pulleys will recover lost shifting precision. Also great for bike shops and home mechanics who want a straight swap with factory hardware and predictable results. If you run a 7-speed GX DH derailleur, this kit is the most reliable way to return your shifting to factory behavior.

Frequently Asked Questions

Will this pulley kit fit my SRAM GX 7-speed derailleur?

Yes — this kit is designed specifically for the SRAM GX DH 7-speed rear derailleur (Model RD-SPP-A0). Verify your derailleur is the GX DH 7-speed variant; it will not fit 9/10/11/12-speed or Eagle derailleurs that use different cage geometries.

Are the pulleys sealed bearings or bushings?

The GX DH pulley kit uses sealed bearing-style pulley construction to reduce ingress of dirt and water, which helps maintain smooth rotation and extends service life under harsh downhill conditions.

What tools do I need to install the pulleys?

Installation requires basic bike tools: a hex key (typically 2.5–3mm or 4mm depending on bolt) and a torque driver if you want to meet factory torque specs. Clean the cage and apply a small smear of grease to bolt threads if recommended by SRAM.

How often should I replace derailleur pulleys?

Replacement intervals depend on riding conditions and mileage; aggressive downhill riders may replace pulleys every season or after heavy contamination, while lighter riders can go much longer. Replace pulleys if you notice lateral play, rough rotation, increased chain noise, or irregular shifting.

Does the kit include both jockey wheels and bolts?

Yes — the kit provides both upper and lower pulley wheels plus the mounting hardware sized for the GX DH 7-speed cage, so it's a complete direct-swap solution.

Can I use this kit on an e-bike?

This kit is optimized for SRAM GX DH 7-speed derailleurs used in gravity and downhill setups, not specifically for e-bike motors. If your e-bike uses a GX DH 7-speed derailleur and chainring/cassette spacing matches, it may fit, but consider higher-load components designed for e-MTBs where applicable.

Buying Guide

When selecting replacement derailleur pulleys, match the kit to your derailleur model and cassette speed first — pulley tooth count, spacing and cage fit are specific to each SRAM group. Choose OEM kits like this GX DH set to preserve factory shifting geometry and avoid tuning headaches. Evaluate bearing type (sealed cartridge vs. bushings) based on your riding conditions: sealed bearings offer better contamination protection for mud and downhill use, while simpler bushings can be lighter and easier to service. Replace pulleys when you detect lateral play, rough rotation, or degraded shifting performance.
