Overview & Technology: Precise hardware for 52T Eagle derailleurs

SRAM's XX1/X01 Eagle 52T B-Bolt/Limit Screw Kit (SRAM model ID: RD-SPP-A0, MPN 11.7518.098.005) provides the exact fasteners you need when fitting Eagle derailleurs to a 52T compatible cassette cage. The kit includes the B-bolt and washer, the B-screw and the pair of high/low limit screws so you have the complete mounting and adjustment set in one pack. Engineered for repeatable adjustment and durability, the hardware is manufactured to SRAM's tolerances so you restore correct B-tension and limit stop settings after service or part replacement. The compact kit ships in a small, lightweight package (4.15" x 2.5" x 1", 0.1 lb), making it convenient to keep as a spares item in your toolbox or on long rides.

Key Features & Construction

The kit contains the specific fasteners required for the 52T Eagle upper pulley cage: a correctly-length B-bolt with washer, the B-screw that sets B-tension, and both high and low limit screws for precise end-stop adjustment. These components are made from high-strength, heat-treated steel with a corrosion-resistant finish for long life under muddy, wet, and salty conditions. Using OEM-spec screws and washers ensures consistent thread engagement, accurate torque behavior and the correct spacing needed to maintain chain wrap and shifting performance with large 52T cassettes. Replacing worn or incorrect hardware eliminates play, prevents chain-suck and reduces skipping across the cassette under load.

Fit & Compatibility

This kit is specifically designed for SRAM XX1 and X01 Eagle rear derailleurs when fitted with the 52T Eagle cage — part number referenced by SRAM as RD-SPP-A0. It restores correct B-tension geometry for Eagle 52T setups and is the recommended replacement when original bolts are lost, corroded or damaged during service. While intended for XX1/X01 Eagle models, the fasteners may also fit other SRAM Eagle derailleurs that use the same bolt lengths and threads. Always confirm thread type and length against your derailleur and consult SRAM installation torque specs before tightening. This kit is not intended for Shimano derailleurs or non-Eagle-specific cages.

Who This Kit Is For

Trail and enduro riders running SRAM 12-speed Eagle drivetrains with the 52T compatible cage will want this kit as an essential spare. It's ideal for mechanics, racers and riders who perform regular drivetrain service, replace damaged hardware after crashes, or are upgrading to a 52T Eagle upper-pulley cage. If you value precise shifting under heavy load — climbing steep, technical lines or sprinting out of corners — using OEM-spec bolts and limit screws keeps your derailleur geometry and performance dialed. Keep a kit in your shop or riding pack to avoid being stranded by a lost or stripped fastener.

Frequently Asked Questions

What exactly is included in this kit?

The kit contains the B-bolt with its washer, the B-screw that sets B-tension, and the pair of high and low limit screws required to set end stops. It's packaged as a complete hardware set for the XX1/X01 Eagle 52T cage.

Is this kit compatible with other SRAM derailleurs?

The kit is designed for XX1 and X01 Eagle derailleurs with the 52T compatible cage (SRAM RD-SPP-A0). It may fit other SRAM Eagle derailleurs that use the same bolt lengths and thread types, but always verify thread size and length before installation.

Do I need special tools to install these screws?

No special tools are required beyond common workshop tools: hex/Allen keys and a screwdriver to hold and adjust the screws. Always follow SRAM's torque specifications and use a torque wrench when possible for precise tightening.

Can I replace only one screw if the others are fine?

Yes. The kit is sold as a set, but you can install only the components you need. Replacing all related fasteners at once is recommended if any are corroded or damaged to ensure consistent thread engagement and correct adjustment behavior.

Is there any corrosion protection on these bolts?

The fasteners are made from heat-treated steel with a corrosion-resistant finish to withstand exposure to weather and trail conditions. For maximum longevity, keep threads clean and use light anti-seize or thread lubricant as advised by SRAM.

Where can I find torque specs for installation?

Refer to SRAM's official service documentation for torque values and installation guidance. If unsure, tighten to a snug setting and then finalize using a torque wrench to the manufacturer's recommended setting to avoid stripping threads or overloading fasteners.

Buying Guide

When replacing derailleur mounting hardware, choose OEM-spec kits matched to your derailleur and cage size. For 52T Eagle setups, this SRAM kit ensures the correct bolt lengths and spacing needed to maintain B-tension and shifting performance. Keep a spare kit on hand if you wrench frequently, race, or ride in harsh conditions. Replacing corroded or damaged screws is a low-cost way to prevent drivetrain problems and keep shifts precise under load.
