Zipp Parts for Zipp 30 & 60

Genuine Zipp service part—the 11.1918.025.000 seal and spacer kit is engineered for Zipp 30 and 60 hub freehub bodies. It pairs with SRAM Model ID HU-SPP-A0 drivers and is supplied as the OEM replacement to maintain factory fit and finish.

The kit uses a precision-molded rubber seal combined with a CNC-machined alloy spacer finished for corrosion resistance. Together they protect bearings from contamination, preserve engagement geometry, and maintain the correct cassette spacing that keeps shifting crisp and drivetrain wear even.

Sealing and protection: The replacement seal re-establishes a reliable barrier against water, grit and road grime—critical for long-term bearing life and smooth hub operation. Proper sealing reduces service frequency and helps bearings run cooler and smoother.

Correct spacing and alignment: The spacer restores the freehub body's intended cassette offset so your derailleur hanger, cassette stack, and wheel dish remain correct. That prevents rubbing, uneven wear, and poor shifting performance on road rides and racers alike.

This part is specifically for Zipp 30 and Zipp 60 hub freehub bodies and is listed as Zipp part number 11.1918.025.000 (Manufacturer part # 11.1918.025.000) and matches SRAM ID HU-SPP-A0. The kit is made up of a precision-molded rubber seal and a CNC-machined alloy spacer with a corrosion-resistant finish to withstand road conditions.

Axle type: QR. Shipping dimensions: 13.8" x 9.1" x 4.6", weight 2.55 lb. Always confirm your hub model and axle standard before ordering; this kit is for Zipp 30/60 hubs that use the specified SRAM-compatible freehub interface.

This is an essential service part for riders who own Zipp 30 or 60 wheels and want to maintain OEM performance — from club racers to endurance road riders. If you’re servicing hubs, replacing a damaged seal, or rebuilding a freehub body, this kit ensures your wheels return to Zipp’s original specifications.

Mechanically inclined cyclists can install the seal and spacer at home with basic hub tools; shops will use it for routine overhauls. If you’re unsure about fit, bring your wheel to a qualified mechanic to confirm compatibility before installation.

When buying freehub seals and spacers, confirm the exact wheel and hub model. Seals vary by freehub interface and axle standard; ordering the correct OEM part number avoids fitment issues and drivetrain problems. Check your hub’s service documentation or the part markings (SRAM model ID HU-SPP-A0) to be sure this kit matches your wheels.

Plan service intervals around seasonal riding and exposure—wet, salty or muddy conditions require more frequent inspection. If you’re unsure about installation, a trained mechanic can replace the seal and spacer while assessing bearing health and re-lubricating the hub for optimal performance.
