Product Details

Overview & Technology

Zipp 11 Speed Conversion Kit (188v7 to 188v8)—manufacturer part number 11.1918.009.000—is a factory replacement/upgrade kit designed to convert Zipp 188v7 hub bodies to the later 188v8 spec so they accept modern SRAM 11-speed road cassettes. The kit is identified by SRAM Model ID HU-SPP-A0 and is the correct OEM solution for maintaining hub performance and cassette fitment. Components are precision-machined from lightweight alloys with hardened engagement surfaces for durability. The conversion retains Zipp's tight tolerances and engagement geometry so the hub's feel, reliability, and weight balance remain true to factory intent while adding 11-speed compatibility.

Key Features

What this kit gives you: a direct-fit conversion path from 188v7 to 188v8 freehub specifications, engineered by Zipp to factory tolerances. Expect a clean cassette fit, consistent shifting, and preserved hub engagement performance. • OEM part: Zipp part 11.1918.009.000, SRAM ID HU-SPP-A0. • Materials: precision-machined alloy bodies with hardened steel engagement points for wear resistance. • Lightweight: minimal added mass—kit ships at 0.25 lb with compact packing. • Serviceable: designed for straightforward installation and maintenance using standard hub tools.

Fit & Compatibility

This conversion kit is specifically for Zipp 188v7 hubs to update them to the 188v8 freehub specification. It is intended for road wheelsets using SRAM 11-speed cassettes. Before purchase, verify your hub model and serial stamp. This kit will not make non-Zipp hubs compatible and is not a universal 11-speed adapter. Installation may require the removal of axle endcaps and standard hub service tools. Some hub axle/endcap combinations (thru-axle vs quick-release) require retaining or swapping specific endcaps—refer to Zipp's service manual for torque specs and step-by-step instructions. If you use Shimano 11-speed or other variants, double-check spline compatibility; this kit is engineered around SRAM 11-speed fitment.

Who It's For

Ideal for road cyclists who own Zipp hubs/wheels built on the 188v7 platform and want to run SRAM 11-speed drivetrains without replacing the entire wheelset. Mechanics and home wrenchers who prefer OEM parts to maintain factory tolerances will value the direct-fit nature of this conversion kit. If you're upgrading your drivetrain to 11-speed or maintaining older Zipp wheels, this kit extends the life and relevance of your hubs while preserving ride quality and engagement characteristics that riders expect from Zipp components.

Frequently Asked Questions

Will this kit work on any Zipp hub?

No. This kit specifically converts Zipp 188v7 hubs to the 188v8 specification. It will not fit other Zipp hub families or non-Zipp hubs. Check your hub's model stamp or serial to confirm it's a 188v7 before ordering.

Is the kit compatible with both SRAM and Shimano 11-speed cassettes?

The kit is engineered for SRAM 11-speed cassette fitment (SRAM Model ID: HU-SPP-A0). While many Shimano and SRAM 11-speed cassettes share spline dimensions, compatibility can vary—verify spline compatibility for your specific cassette brand before installation.

What tools are needed to install the conversion kit?

Basic hub service tools are required: appropriate hex/torx for axle removal, cone wrenches or endcap tools as applicable, and a torque wrench for reassembly. Refer to Zipp's service manual for exact tool sizes and torque specs to avoid damage.

Does the kit include bearings or just the freehub body components?

This kit primarily contains the conversion/freehub components required to change 188v7 to 188v8. Bearings are typically not included—inspect your hub bearings during service and replace if worn. Check the product contents list or consult us if you need replacement bearings.

Can I install this myself or should I use a bike shop?

Experienced home mechanics comfortable with hub service can install the kit with the right tools and Zipp's instructions. If you're unsure about axle/endcap configurations or torque settings, we recommend having a qualified shop perform the swap to ensure proper assembly and safety.

What should I check after installation?

After installation, confirm cassette seating, freehub rotation, bearing preload, and that axle/endcaps are torqued to spec. Test shifting under load in a safe area to verify smooth engagement and no unusual play or noise.

Buying Guide

If you own Zipp wheels built on the 188v7 platform and are upgrading to an 11-speed SRAM drivetrain, this OEM conversion kit is the most cost-effective path to compatibility. It preserves your existing rimset and hub shell while updating the freehub interface to accept modern cassettes. Before purchasing, confirm your hub model and inspect internal parts for wear. If bearings or seals are old, consider replacing them during the conversion for a complete service. For peace of mind, professional installation at a local bike shop ensures correct torque and endcap fitment.
