Product Details

Overview & Technology

SRAM BB30 Wave Washer and BB Shield (Part #11.6415.007.020) is an OEM replacement assembly designed to restore bearing preload and keep contaminants out of BB30 press-fit bearings. The kit includes a precision-formed wave washer and a corrosion-resistant shield engineered to work with SRAM BB30 bearings and compatible frames. The wave washer is a heat-treated spring steel component that supplies consistent axial preload to eliminate play without overloading the bearing, while the shield features a treated stainless-steel face and integrated polymer lip to block water, grit and grime. Together they extend service intervals and preserve smooth bearing rotation under real-world riding conditions.

Key Features & Benefits

Purpose-built components: The assembly addresses two common wear points in BB30 systems — preload hardware and the protective sealing surface — restoring factory performance with OEM parts. Replacing worn wave washers prevents side-to-side play and improves pedaling efficiency. • Corrosion-resistant shield — stainless-steel face with protective finish for durability in wet conditions. • Heat-treated spring steel wave washer — maintains consistent preload and returns to shape after repeated loads. • Integrated polymer lip — improves dust and splash protection for longer bearing life.

Fit, Compatibility & Installation

This assembly is specified for BB30 press-fit systems and is an OEM SRAM replacement (SRAM Model ID: BB-SPP-A0, Manufacturer Part #: 11.6415.007.020). It's intended for use with SRAM BB30 bearings and compatible frames that use the BB30 standard. Verify your frame uses BB30 (46mm bore) and consult your bike or bearing manufacturer's compatibility notes before installing. Installation is straightforward for a mechanic familiar with press-fit bottom brackets: remove the cranks and bearings, clean the shell, install bearings per manufacturer torque/press-fit instructions, then fit the shield and wave washer to achieve the correct preload. If you're unsure, have a qualified bike tech press the bearings to avoid damaging the shell or seals.

Who This Is For

This kit is ideal for road riders, mechanics and home wrenchers who own a BB30-equipped bike and want an OEM-quality replacement to restore bearing preload and improve contamination protection. It's especially useful when troubleshooting creaks, lateral play, or premature bearing wear in BB30 systems. If you maintain your own bikes or run performance road setups where smooth, reliable bottom bracket rotation matters, this small, economical part provides measurable gains in feel and longevity without replacing the entire bearing assembly.

Frequently Asked Questions

What does the wave washer do and why replace it?

The wave washer is a spring element that provides axial preload to the BB30 bearing stack. Over time it can fatigue or lose resilience, causing play or uneven bearing load. Replacing it restores correct preload and reduces premature bearing wear.

Is this compatible with all BB30 bottom bracket bearings?

This assembly is designed for SRAM BB30 systems and compatible BB30 press-fit bearings. While many BB30 bearings share the standard dimensions, always confirm compatibility with your bearing or frame manufacturer before installation.

Can I install this myself at home?

If you have experience with press-fit bottom brackets and the right tools (bearing press, torque tools), you can install it yourself. If you're unsure, we recommend a professional bike mechanic to avoid damaging bearings or the frame shell.

How does the shield improve bearing life?

The shield blocks contaminants like water, grit and road spray from reaching the bearing contact surfaces. With a corrosion-resistant face and polymer sealing lip, it reduces ingress and helps maintain lubrication, extending service intervals.

What are the exact part numbers for ordering?

This product is SRAM Part #11.6415.007.020, Product Number 380461 and SRAM Model ID BB-SPP-A0. Use these identifiers to ensure you receive the correct OEM assembly.

How long will replacing this assembly extend my bearing life?

Service life depends on riding conditions and maintenance, but replacing a worn shield and wave washer can significantly reduce contaminant ingress and incorrect preload — commonly translating to months or years of improved bearing life under normal road use.

Buying Guide

When replacing BB30 preload hardware and seals, choose OEM or OEM-equivalent parts to preserve intended clearances and sealing geometry. Look for assemblies that match your bearing supplier and verify the model/part number — in this case SRAM Model ID BB-SPP-A0, Part #11.6415.007.020. If you're rebuilding a BB30 bottom bracket, consider replacing seals and preload hardware together and inspect bearings for pitting or roughness. Replacing worn components in pairs (both sides) and using a proper bearing press will give the best long-term results.
