Product Details

Overview & Technology

Zipp Disc Conversion Kit 11Sp → Track (Product No. 090808, MPN 11.1918.026.000) lets you convert a Zipp 11-speed disc wheel hub to a dedicated track axle standard. Designed and supplied by Zipp with SRAM Model ID HU-SPP-A0, this conversion kit is built to the tolerances and finish quality you expect from a premium wheel brand. The kit uses precision-machined alloy end caps and hardened steel interface hardware to deliver a rigid, reliable axle fit for high-cadence, fixed-gear track riding. Surfaces are anodized and chamfered for repeatable seating and corrosion resistance, while the compact package retains the low weight and stiffness advantages of your original Zipp hub.

Key Features

Purpose-built conversion: Converts Zipp 11-speed disc hubs to a track axle configuration compatible with velodrome setups and fixed-gear track frames. Core benefits include: • SRAM Model ID HU-SPP-A0: Official Zipp/SRAM part ID for reliable compatibility. • Precision-machined alloy caps: Lightweight, anodized aluminum for accurate seating and durability. • Hardened steel interface sleeve: Abrasion-resistant contact surfaces for long service life under track loads. • Compact, low-weight design: Keeps rotating mass minimal and preserves wheel stiffness. • Complete hardware included: Everything needed to switch your hub standard (check your hub manual for specific fit steps).

Fit & Compatibility

This conversion kit is specifically designed for Zipp disc wheels that originally accept an 11-speed cassette and are compatible with Zipp's conversion system. Confirm your wheel's model and hub spec before ordering — the kit lists compatible units via SRAM Model ID HU-SPP-A0 and Zipp MPN 11.1918.026.000. Physical shipping dimensions are 12.4" x 9.1" x 4.6" and the kit weight is approximately 1.4 lb. Installation typically requires basic shop tools and a torque wrench; refer to your wheel/hub manual for torque values and step-by-step instructions. If in doubt, have a wheel technician fit the kit to ensure correct bearing preload and axle alignment.

Who it's for

This kit is aimed at riders who want to move a Zipp disc wheel from road or training use to the velodrome — coaches, track teams, and serious fixed-gear competitors who need a fast, manufacturer-approved conversion. It's also useful for bike shops and mechanics who service athletes and maintain flexible wheel fleets. If you own a Zipp disc wheel and need a track axle option without buying a separate wheelset, this kit saves money and storage while delivering the fit quality required for high-speed, fixed-gear track work.

Frequently Asked Questions

Will this kit fit any Zipp disc wheel?

This kit is designed for Zipp disc wheels that use the Zipp 11-speed hub standard and are listed compatible with SRAM Model ID HU-SPP-A0. Always verify your wheel's model and hub spec before purchasing; consult your Zipp wheel manual or contact Forest Bikes support for help confirming fit.

What tools are required for installation?

Basic shop tools plus a torque wrench are typically required for installation. You may need hex keys, cone wrenches or axle-specific tools depending on your hub. Follow Zipp's service manual for the correct torque settings and installation steps; a professional mechanic can also fit the kit to ensure correct bearing preload.

Does the kit include axle bearings or replace bearings?

The conversion kit provides end caps and interface hardware to convert the hub standard; it does not typically include new hub bearings. Inspect bearing condition during installation and replace bearings if worn or contaminated to maintain safe and precise performance.

Is it legal/safe to use a converted wheel on the road?

Track axle conversions are intended for fixed-gear, velodrome use where track standards and safety practices apply. If you plan to ride on the road, ensure the conversion meets local regulations and that the axle/lockring setup is appropriate for on-road conditions. Consult a mechanic to confirm safety.

What is the warranty or return policy for this kit?

Warranty coverage follows Zipp's manufacturer terms and Forest Bikes' returns policy. Inspect parts on arrival and contact Forest Bikes within the return window if there are defects or fitment issues. Retain packaging and documentation (Product No. 090808, MPN 11.1918.026.000) for any warranty claim.

Can I install this myself at home?

If you have intermediate mechanical skills and the correct tools, you can install the kit yourself by following Zipp's guidance. However, for track-critical fitment — bearing preload, axle alignment and torque — we recommend professional installation at a bike shop to ensure optimal and safe performance.

Buying Guide

When buying a disc-to-track conversion kit, prioritize manufacturer-matched parts like Zipp's HU-SPP-A0 to ensure exact fit and reliable performance under high track loads. Check compatibility with your wheel model, inspect bearings and hub condition, and budget for professional installation if you don't have experience with axle preload and torque procedures. Also consider whether a conversion suits your long-term needs — conversions are great for teams and racers who toggle wheels between road and track use, but if you regularly race on the track a dedicated track wheelset may be a better long-term investment.
