Product Details

Overview & Technology

SRAM X5 Pulley Set (Manufacturer Part #: 11.7518.019.000, Product #: 270365, SRAM Model ID: RD-SPP-A0) is the OEM replacement pulley kit for SRAM X5 rear derailleurs. These pulley wheels are engineered to return your drivetrain to quiet, accurate shifting after wear or damage and are sized to match the factory geometry of X5 derailleurs. The pulleys are molded from long-life composite material and run on low-friction internals designed for consistent rotation and minimal drag. The compact shipping footprint (5.6" x 3.7" x 0.7") and light weight (0.1 lb) reflect the simple, service-oriented nature of this part — small, precise, and built to fit.

Key Features

Durable construction: Precision-molded composite wheels resist impact and wear for long service intervals. The design balances stiffness and noise reduction so the drivetrain stays smooth under load. Factory fitment: Manufactured to SRAM's OEM tolerances so the pulley spacing and tooth profile match X5 derailleur geometry for accurate chain tracking. Ideal for replacing worn jockey wheels without needing derailleur adjustment beyond routine indexing.

Fit & Compatibility

This pulley set is a direct replacement for the SRAM X5 rear derailleur family. Use the Manufacturer Part # 11.7518.019.000 and Product # 270365 to confirm exact fit for your bike. It is specifically specified for the SRAM X5 model (SRAM Model ID: RD-SPP-A0). Note: pulley mounting hardware can vary by model year and derailleur version. These wheels are intended to drop into the factory cage using the original bolts; confirm whether your kit includes bolts or if you should reuse existing fasteners. If your SRAM derailleur is a different series (e.g., GX, NX, or higher/lower), check tooth count and spacing before purchase.

Who It's For

This pulley set is aimed at mountain bikers and mechanics who run SRAM X5 derailleurs and want a reliable, OEM-quality replacement. Whether you service your own bike, run a fleet of commuter bikes, or need a quick repair part for weekend trail riding, these pulleys restore crisp shifting without expensive upgrades. Recommended for riders who prioritize dependable shifting and low maintenance cost over high-end ceramic bearings. A great budget-conscious maintenance part for recreational, trail, or entry-level mountain bike use.

Frequently Asked Questions

Will these pulleys fit my SRAM X5 derailleur?

Yes — this set is specified as the direct replacement for SRAM X5 rear derailleurs (SRAM Model ID: RD-SPP-A0). Use the manufacturer part number 11.7518.019.000 or product number 270365 to confirm compatibility with your bike's model year.

Do the pulleys come with mounting bolts?

Mounting hardware can vary by batch and model year. While many pulley kits include bolts, some riders reuse the original mounting bolts. Check the product listing or with Forest Bikes if included bolts are required for your installation.

Are these pulley bearings sealed or bushings?

These pulleys use low-friction internals designed for long life in OEM SRAM X5 spec. Routine inspection and light lubrication during service will maximize life. For specific bearing type (sealed cartridge vs. bushing) verify with the product part sheet or contact our tech team.

How often should I replace derailleur pulleys?

Replacement intervals depend on conditions and mileage — heavy muddy or sand exposure speeds wear. Inspect pulleys every 1,000–2,000 km: look for tooth wear, excessive play, or rough rotation. Replace both upper and lower pulleys if either shows significant wear to maintain shifting accuracy.

Can I use these pulleys with other SRAM derailleur models?

They are designed for SRAM X5 geometry and may not perfectly fit other series due to tooth profile and spacing differences. Cross-compatibility is possible with some models, but we recommend matching part numbers or consulting our tech team for non-X5 derailleurs.

How do I install the pulley wheels?

Installation requires removing the derailleur cage, swapping out the pulley wheels, and reinstalling the cage bolts. Use correct torque for the mounting bolts (refer to SRAM torque specs), ensure pulleys spin freely, and re-index the derailleur if necessary. If unsure, have a shop perform the swap.

Buying Guide

When replacing derailleur pulleys, match the OEM part number to ensure tooth profile and spacing are identical to the factory specification. For SRAM X5 derailleurs, choose the X5 pulley set (11.7518.019.000) to avoid chain rub or indexing problems. Consider replacing both pulleys at once and inspecting the chain and cassette — worn chainrings or cassettes accelerate pulley wear. For frequent off-road riders, select pulley sets with sealed bearings or higher-end materials if you want longer service intervals. For routine trail and commuter use, the SRAM X5 pulley set offers an excellent balance of durability, cost, and factory fit.
