Product Details

Overview & Technology

SRAM's XX SL T-Type Pulley Kit is built as a precision replacement and upgrade for the top-tier XX SL T-Type rear derailleur used on Eagle AXS drivetrains. The kit includes a 14-tooth upper pulley and a 16-tooth lower pulley mounted on a silver metal spider, plus two anodized T25 aluminum pulley bolts — everything you need to restore shifting crispness and reduce drivetrain noise. This kit mirrors SRAM's high-end construction philosophy: low weight without sacrificing stiffness or durability. The metal spider design improves lateral stability under load for consistent chain tracking, while the anodized aluminum hardware reduces mass versus steel bolts and resists corrosion for long-term reliability on trail rides and races.

Key Features & Benefits

High-precision tooth counts: the 14T upper and 16T lower combination maintains the intended chain wrap and actuation ratio of the XX SL T-Type system, preserving crisp, accurate shifts across the cassette. Riders who expect race-level performance will notice reduced chain lash and smoother transitions under power. Metal spider construction and aluminum bolts: the silver metal spider offers extra stiffness and wear resistance compared to plastic carriers, while the included T25 aluminum bolts cut weight and look at home on premium builds. Together they increase pulley life and keep your derailleur performing like new.

Fit, Compatibility & Installation

This pulley kit is specifically compatible with SRAM XX SL T-Type rear derailleurs and is intended for use with SRAM Eagle AXS electronic drivetrains. Manufacturer Model ID RD-SPP-A0 and Part # 11.7518.104.006 correspond to this exact replacement; confirm your derailleur is the XX SL T-Type before purchasing. Installation is straightforward: remove the old pulleys, install the 14T upper and 16T lower pulleys onto the metal spider, and secure with the supplied T25 aluminum bolts using a T25 driver. The kit ships light — 0.1 lb — in compact packaging (4.2" x 3" x 0.75"). If in doubt, have a mechanic torque bolts to SRAM's recommended spec or consult a shop for a quick swap and tune.

Who This Is For

This pulley kit is aimed at mountain riders who own a SRAM XX SL T-Type Eagle AXS derailleur and demand top-level drivetrain performance. It's ideal for racers, lightweight-focused builders, and riders replacing worn pulleys with a like-for-like or slightly upgraded metal-spider option. If you run a mixed-brand or older SRAM derailleur (non T-Type), or if your drivetrain uses different tooth counts, this kit is not compatible — check model references before purchase. For trail riders who value low noise, precise shifting, and reduced drivetrain wear, this kit is a high-value service item.

Frequently Asked Questions

Is this pulley kit compatible with all SRAM derailleurs?

No. This kit is specifically designed for the SRAM XX SL T-Type rear derailleur used on Eagle AXS systems. It will not fit non-T-Type derailleurs or older SRAM models. Always confirm your derailleur model before ordering.

What tools do I need to install the pulleys?

Installation requires a T25 driver to remove and install the included aluminum bolts. Basic bike maintenance tools and a clean workspace are recommended. If you're unsure about torque or alignment, a professional tune at a shop is recommended.

Do the pulleys come pre-greased or sealed?

SRAM supplies these pulleys ready to install; they typically have factory lubrication applied to the bearing areas. After installation, check for smooth rotation and periodically inspect and clean the pulleys as part of routine drivetrain maintenance.

Will these pulleys change my cassette range or drivetrain performance?

No — the 14T/16T combination preserves the intended chain wrap and actuation of the XX SL T-Type system. Performance improvements are in shifting smoothness, reduced noise, and longer pulley life compared to worn or degraded stock pulleys.

Are the bolts durable enough for off-road use?

Yes. The kit includes anodized aluminum T25 bolts that are lightweight yet corrosion-resistant. They’re suitable for normal off-road use; inspect bolts during routine checks and replace if damaged after impacts.

What is the official SRAM part number for this kit?

The manufacturer part number is 11.7518.104.006 and the SRAM Model ID is RD-SPP-A0. Forest Bikes product number for ordering is 270976.

Buying Guide

When buying pulley kits, match the kit to your exact derailleur model — tooth counts, mounting style, and carrier design vary across SRAM families. For high-performance MTB drivetrains, metal-spider pulleys offer better stiffness and wear resistance than plastic carriers, making them a smart choice if you prioritize longevity and precise shifting. Also consider whether you want OEM-spec replacements or aftermarket options with ceramic bearings or different tooth counts. For most XX SL T-Type owners, this OEM SRAM kit is the most straightforward way to restore factory performance with minimal fuss.
