Product Details

Overview & technology

Zipp 88/188 hub bearings (part no. 11.1915.028.000 / 61803-2RS) are sealed cartridge bearings engineered to the manufacturer's specification to fit Zipp 88 and 188 hub platforms. These bearings measure 17 x 26 x 5 mm and are made from hardened steel for balanced durability and rolling performance. The "2RS" double-seal configuration keeps grease in and contaminants out, providing reliable low-friction rotation in wet and dry conditions. As sealed cartridges they arrive pre-lubricated and are intended as direct-replacement units — no re-greasing or re-build required during installation.

Key features & benefits

These bearings are OEM-grade Zipp components (SRAM model ID: HU-SPP-A0) built to the tolerances expected for high-performance road hubs. The hardened steel races and precision steel balls provide predictable longevity while maintaining smooth rolling characteristics under load. Real-world benefits: • Sealed 2RS design reduces ingress of water and grit, extending hub life. • Pre-lubricated cartridge for quick, mess-free replacement. • Exact 17x26x5mm sizing ensures a precise fit in Zipp 88/188 hub shells. • OEM Zipp grade maintains intended bearing preload and wheel feel.

Fit, installation & compatibility

These bearings are designed specifically for Zipp 88 and 188 hub families and carry the Zipp part number 11.1915.028.000 and SRAM ID HU-SPP-A0 for cross-reference. The cartridge is 17x26x5mm — confirm your hub accepts 61803-size cartridges before purchasing. Installation requires a proper bearing press or suitably sized drift to avoid damaging the seal or race. Replace bearings one at a time to preserve axle & spacer orientation, and always follow Zipp or SRAM hub service instructions for torque and preload settings. If you’re unsure, a professional wheel service will ensure correct fit and alignment.

Who should buy the Zipp 88/188 bearings

These bearings are ideal for road cyclists who own Zipp 88 or 188 wheels and need an OEM replacement to restore hub performance. If your hubs exhibit roughness, play, or increased rolling resistance, swapping to a fresh set of 61803-2RS cartridges is a cost-effective way to refresh wheel performance without replacing the entire hub. Mechanics, racers, and enthusiasts who prefer factory-spec components will appreciate the exact fit and hassle-free installation of these sealed cartridges. Riders who demand the longest service life in wet or gritty conditions will benefit from the sealed 2RS construction and hardened steel materials.

Frequently Asked Questions

Are these bearings compatible with my Zipp 88 or 188 hub?

Yes — the 61803 (17x26x5mm) sealed cartridge is the OEM replacement for Zipp 88 and 188 hubs. Confirm your hub calls for 61803-size cartridges or cross-reference Zipp part number 11.1915.028.000 or SRAM ID HU-SPP-A0 before ordering.

Can I re-grease or rebuild these sealed cartridges?

Sealed cartridge bearings are factory pre-lubricated and intended as non-serviceable units. Attempting to open the seals risks contamination and will void the intended performance; replace the cartridge when lubrication or smoothness degrades.

What tools do I need to install these bearings?

Use a proper bearing press or a correctly sized drift to press the cartridge into the hub shell squarely. Avoid hammering directly on the seal face; that can damage the seals. If you don't have the tools, have a qualified bike shop perform the install.

How do I know when to replace my hub bearings?

Replace bearings when you feel roughness, noise, or lateral play at the hub, or if rolling resistance increases. Also replace them if seals are visibly damaged or contaminated. Routine checks during wheel service will catch issues early.

Are there ceramic alternatives available?

Ceramic-bearing upgrades exist, but OEM Zipp steel cartridges offer a reliable balance of durability, cost, and compatibility. Choose ceramic only if you understand the trade-offs — higher cost and sometimes different preloads or fitment may be required.

What's the shipping size and weight for this item?

This product ships in packaging sized approximately 12.3" x 9.1" x 4.6" and weighs about 1.9 lb (shipping weight). Actual package size may vary with multi-item orders.

Buying Guide

When buying replacement hub bearings, match the exact cartridge size and seal type to your hub — in this case 61803 (17x26x5 mm) with 2RS double seals. Choose OEM-grade bearings for guaranteed fit and predictable preload settings, or upgrade only if you confirm compatibility with axle spacers and endcaps. Plan on replacing bearings in pairs per wheel and have the right press or professional mechanic to avoid seal/race damage. For wet or mixed-weather riding, prioritize sealed cartridges (2RS) to keep contaminants out and extend service intervals.
