Product Details

Overview & Technology: Fast, Tubeless-Ready Aero Performance

The Zipp 404 Firecrest Tubeless Disc B1 blends aerodynamic depth with a modern wide rim profile to deliver stable, efficient rolling for road riders. The 58mm Firecrest rim uses a hookless tubeless-ready design with a 23mm internal width and 28mm external width to create a larger, more stable tire contact patch — faster on smooth roads and more composed on rough surfaces. Construction is high-modulus carbon with a double-wall layup optimized for weight, stiffness and impact resistance. The rim bed is intentionally engineered for easy tire installation and reliable bead seating, and the finished wheelset ships with a center-lock rotor lockring included for instant disc compatibility.

Key Features & Build Details

Precision hubs and premium spokes: The ZR1 DB hub is engineered in Germany with improved seals for durability and a 66-point engagement mechanism for crisp power transfer and quick responsiveness. Sapim CX-Ray spokes deliver an ideal balance of aerodynamics, strength and durability at each junction. The rim is a double-wall carbon layup with a tubeless, hookless profile, drilled for 24 spokes and delivered in a 700C / 622 diameter. Valve is Presta, freehub options include Shimano HG 11 (and SRAM XD-R on select rear variants). Total weight is listed at 1470g for the wheelset and the rims carry Zipp's Lifetime Warranty.

Fit, Compatibility & Installation Notes

This family offers both front and rear variants: 12mm thru-axle front (100mm spacing) and 12mm rear options (142mm spacing) with center-lock disc interface. The product ships with 12mm front and rear end caps where applicable, and the lockring for center-lock rotors is included. Rim internal width range is 22–27.9mm and the wheel is tubeless-ready and hookless — that means you can run modern wider road tires (best results with 25–32mm tires) and lower pressures for improved comfort and rolling resistance. Verify freehub compatibility (Shimano HG 11 or SRAM XD-R on select rears) and ensure your frame and fork accept a 58mm deep/12mm TA disc wheelpair before ordering.

Who This Wheel Is For

The 404 Firecrest Tubeless Disc B1 is targeted at performance-driven road cyclists who want aero efficiency without sacrificing comfort on real-world roads. If you race criteriums, time trials, or sportives — or you prioritize long-day speed and stable handling on rough tarmac — these wheels deliver a clear performance advantage. They also appeal to riders upgrading from narrower rims who want better tyre support, improved cornering stability and modern tubeless convenience while retaining a deep, aero profile for sustained speed.

Frequently Asked Questions

Is this wheel tubeless-ready and can I use inner tubes?

Yes — the 404 Firecrest B1 rims are tubeless-ready with a hookless profile. You can run traditional inner tubes if you prefer, but they’re optimized for tubeless setups which provide lower rolling resistance, puncture protection with sealant, and the ability to run lower pressures for improved comfort.

What tire widths work best with a 23mm internal rim?

Zipp's 23mm internal width pairs best with modern road tire widths in the 25–32mm range for the best balance of aerodynamics, comfort and safety. Wider tires increase volume and ride quality; always follow the tire manufacturer's pressure recommendations for hookless rims.

Which freehub bodies are compatible with the rear wheel?

Rear variants are available with a Shimano HG 11 freehub body and, on a separate SKU, an SRAM XD-R option for SRAM 12-speed drivers. Confirm the rear variant you select matches your drivetrain before purchase.

What axle standards and spacings are supported?

Front wheels use a 12mm thru-axle with 100mm spacing; rear wheels use 12mm thru-axles with 142mm spacing depending on the variant. These wheels use a center-lock rotor interface and ship with the lockring included.

How durable are the hubs and what maintenance do they need?

ZR1 DB hubs are engineered in Germany with improved seal design for enhanced durability and contamination resistance. They feature 66 points of engagement for quick pickup. Routine maintenance involves periodic cleaning, regreasing bearings and seal inspection; follow Zipp’s service intervals or have a qualified mechanic service them for peak life.

Does the wheelset come with skewers or rotors?

Skewers are not included. The wheels include a center-lock lockring for rotors, but brake rotors are not supplied. You’ll need to source rotors and thru-axles or adapters to match your bike if they are not already fitted.

Buying Guide

When choosing an aero disc wheel like the Zipp 404 Firecrest, consider your primary riding conditions: deeper rims (58mm) reward sustained speed and time-trial efforts but can be more affected by crosswinds than shallower options. The modern wide 23mm internal rim makes this wheelset a versatile choice for road riders who want aero gains plus improved comfort and real-world handling. Check fitment — axle type, freehub body and rotor standard — and pick the rear freehub option that matches your drivetrain. If you plan to run tubeless, budget for sealant and a reliable floor pump or tubeless inflator. Finally, pair these rims with tires in the 25–32mm range for best performance and safety on hookless tubeless rims.
