Product Details

Overview & Technology

SRAM's XX T-Type Pulley Kit (Model RD-SPP-A0, MPN 11.7518.104.007, Product #270977) replaces the stock pulley set on XX T-Type Eagle AXS rear derailleurs. The kit includes a 14-tooth upper and 16-tooth lower metal spider pulley, plus two anodized aluminum pulley screws — a lightweight, durable combination engineered for modern 12-speed Eagle drivetrains. The metal spider construction maximizes stiffness and wear resistance compared to plastic cages, while precisely machined tooth profiles preserve chain line and engagement with Eagle chains. The result is consistent, low-friction rotation under load and improved longevity for riders who demand top-level drivetrain performance on the trail.

Key Features & Benefits

Durable metal spider pulleys: Both pulleys are metal-spider designs to resist deformation and wear, giving more consistent shifting and longer service life when compared to standard plastic pulley wheels. Precision hardware: The included aluminum pulley screws are lightweight, corrosion-resistant, and sized specifically for XX T-Type assemblies. Together the components reduce parasitic flex and help maintain tight chain control on technical terrain.

Fit, Compatibility & Specifications

This kit is specifically compatible with SRAM XX T-Type rear derailleurs and is intended for use on Eagle AXS wireless 12-speed drivetrains. Confirm your derailleur is an XX T-Type model before purchase; the pulleys and screw length/profile are tailored to that assembly and may not fit other SRAM models or third‑party derailleurs. Shipping dimensions: 4" x 0.5" x 2.5". Weight: 0.1 lb. SRAM Model ID RD-SPP-A0. Manufacturer Part #: 11.7518.104.007. Follow SRAM's installation and torque recommendations and use a light smear of grease on screw threads to prevent corrosion and ensure smooth assembly.

Who This Is For

Riders running SRAM's top-tier XX T-Type Eagle AXS drivetrain who want a direct, performance-oriented pulley upgrade will benefit most. It's ideal for mountain bikers who chase long days in the hills, racers who demand consistent shifting under load, and anyone seeking longer-lasting, stiffer pulley wheels that keep the chain under control on rough trails. If you prioritize weight savings and optimized drivetrain performance on technical terrain — without a full derailleur replacement — this pulley kit is a high-value, straightforward upgrade.

Frequently Asked Questions

Will these pulleys fit my non-XX T-Type SRAM derailleur?

No — this kit is engineered specifically for SRAM XX T-Type rear derailleurs. Screw length, spider geometry and tooth profiles are tuned to the XX T-Type cage. They may not seat correctly or could cause shifting issues on other SRAM models or third-party derailleurs.

Are bearings included or serviceable?

The kit supplies the metal spider pulley wheels and aluminum screws as sold by SRAM. Internal bearing or bushing details depend on the pulley assembly design; follow SRAM service documentation for bearing servicing or replacement intervals. If you need sealed cartridge replacements, check SRAM's parts list or contact Forest Bikes for compatible options.

How difficult is installation?

Installation is straightforward for anyone comfortable with basic drivetrain work. Remove the old pulleys, clean the cage, then install the metal spider pulleys with the supplied screws. Use a light smear of grease on threads and tighten to SRAM's recommended torque. If unsure, have a shop tech fit them to avoid misalignment.

Will these change my gearing or chain length requirements?

No major gearing change is expected from the 14T/16T combo versus typical stock pulley sizes, but always check chain wrap and tension after installation. If you switch to significantly larger pulley sizes outside SRAM specifications, chain length and B-screw adjustment could be affected.

How do these pulleys affect shifting performance?

The metal spider design improves stiffness and resists wear, which helps maintain precise chain path and reduces lateral play in the cage. That leads to crisper, more consistent shifts — especially under long-term use and demanding trail conditions.

Buying Guide

When choosing replacement rear derailleur pulleys, prioritize compatibility, material, and bearing type. Match the kit to your derailleur model (here: XX T-Type) to ensure correct screw length, spider geometry, and tooth profile. Metal spider pulleys trade slightly higher weight for superior stiffness and durability compared with plastic options — a good choice for riders who want long-term performance under heavy use. Consider maintenance and serviceability: sealed bearing pulleys can roll more freely and require less attention, while simple bushing designs can be lighter and easier to swap. Finally, weigh the benefits of improved shifting consistency and longevity against cost and intended use; upgrades like the SRAM XX T-Type Pulley Kit are especially worthwhile for aggressive trail riders and racers running Eagle AXS systems.
