Product Details

Overview & Technology

Zipp Oval Nipple Washers are precision-formed washers engineered specifically for Zipp Firecrest rim beds. Supplied in a convenient bag of 50 (part #11.1915.026.020 / SRAM WH-SPP-A0), these washers feature an oval profile that matches the Firecrest rim geometry to give a larger, centered contact area between the nipple and the rim. Manufactured from corrosion-resistant, precision-stamped metal, the washers are thin enough to avoid changing spoke tension or stack height while still protecting the rim from nipple abrasion and helping distribute load across the spoke hole. The result: cleaner builds, longer rim life, and more consistent wheel tension over time.

Key Features & Benefits

Designed for reliable wheel builds. The oval shape seats into the Firecrest bed to prevent nipple migration and reduce stress concentrations around the spoke hole. That gives more predictable tension and fewer spoke / rim problems during routine service or hard efforts. Real-world benefits include: • Improved nipple-to-rim contact area to reduce wear and elongation of the spoke hole. • Corrosion-resistant finish for durability in wet and salty conditions. • Thin, precision stamping preserves spoke length and rim tape fit while adding protection.

Fit, Compatibility & Specifications

These washers are OEM-specified for Zipp Firecrest wheels and are identified by Zipp part number 11.1915.026.020 and SRAM Model ID WH-SPP-A0. Each bag contains 50 washers — enough for full wheel builds on most road wheelsets plus spares for future service. While optimized for Firecrest rims, the shallow, oval profile can work with other rims that have similar counterbore geometry. Always test fit on one spoke before building a full wheel. Shipping dimensions: 11" x 6" x 1.5", weight: 0.5 lb.

Who These Washers Are For

These washers are a must-have for mechanics and riders who own or service Zipp Firecrest wheels — from club racers and triathletes to workshop technicians. If you routinely rebuild or true wheels, or want to protect expensive carbon rims from nipple wear, these are a straightforward, low-cost upgrade. They’re also useful for shops stocking OEM replacement parts: the 50-piece bag provides parts for multiple builds or repairs and keeps wheelsets road-ready with correct Zipp-specified hardware.

Frequently Asked Questions

How many washers do I need per wheel?

Most road wheels use one washer per spoke nipple. For a 24-spoke wheel you’ll need 24 washers, so a 50-piece bag covers both wheels on most road and tri wheelsets plus a couple of spares.

Are these washers compatible with all Zipp wheels?

They’re specifically made for Zipp Firecrest rims and are recommended for wheelsets with that rim bed profile. They may fit other rims with a similar counterbore, but you should test a single washer before committing to a full build.

What material are the washers made from and will they corrode?

These are precision-stamped, corrosion-resistant metal washers designed for longevity in road conditions. While not impervious to extreme environments, their finish helps resist rust and prolongs service life compared with untreated metal.

Do I need washers if I use brass nipples or alloy nipples?

Washers help protect the rim regardless of nipple material. With deeper-set nipple heads or softer rim materials (like many carbon rims), the washer prevents direct metal-on-carbon contact and reduces wear, so they’re recommended with either brass or alloy nipples on Firecrest rims.

Can I install these with tubeless rim tape?

Yes. Install the washer under the nipple head before you fit rim tape or when mounting the nipple from the spoke side during a wheel build. Ensure the tape and washer stack won’t prevent proper sealing of your tubeless setup; most thin rim tapes remain compatible.

How often should I replace the washers?

Replace washers whenever you disassemble the wheel or notice visible wear, corrosion, or deformation. They’re inexpensive and a good preventive part during every full rebuild or after heavy impacts.

Buying Guide

When buying nipple washers, match the washer profile to your rim's counterbore — Zipp's oval washers are designed for Firecrest beds and should be used when assembling or servicing those wheels. Choose OEM parts where possible to maintain intended fit and performance. Consider pack size (50 is convenient for multiple builds or shop use), material/resistance to corrosion, and whether the washer alters nipple length or rim tape fit. Always test-fit and inspect before final tensioning to ensure even seating and consistent spoke tension.
