Hunt 54_58 Aerodynamicist Carbon XD-R Wheelset

Description:

Built for aerodynamic advantage, the Hunt 54_58 wheelset features CFD-optimized rim profiles—wider front, deeper rear—proven in wind tunnel testing to enhance speed and stability without sacrificing weight. Aero wing spokes cut through air resistance while remaining serviceable. The H_Ratchet 40T DBL hub engages at 9° with minimal material, paired with Enduro™ ABEC 5 chromium steel bearings for sustained rolling efficiency. Precision engineering focused on racing performance.

Key Features:

No Compromise Rim Profiles

Wind tunnel tests prove these are the fastest wheels in the 50-59mm category. The 54.5mm front and 58mm rear depths, shaped through CFD analysis, cut through air while maintaining control. Wide external dimensions (31.7mm front, 30mm rear) improve aerodynamics without adding weight. The 22mm internal hooked rim works with all tubeless and clincher tyres from 25-50mm.

Reliable, Rapid H_Ratchet Hub System

H_Ratchet 40T DBL, is a dual-sided ratchet system with 40-tooth drive rings offers rapid and reliable 9˚ engagement for quick response to pedal inputs. 6066 aluminium alloy hub shell with extra strong 7075-T6 alloy axle and freehub body for durability. H_Ceramik reinforced coating to protect against gouging.

Recyclable H_Cyclo Technology

Fully recyclable thermoset epoxy resin technology allows for the separation and re-use of both the carbon fibre material and resin components at end-of-life without creating waste solvents or pollutants. 

Low Friction, High Durability Bearings

High performance chromium steel Enduro™ ABEC 5 bearings are specifically designed for cycling applications to provide excellent longevity and low rolling resistance, no matter the weather.

Aerodynamic Wing Spokes

Built for strength and aero efficiency, the Pillar Wing spokes feature an aerofoil profile to reduce drag, with reinforced butting near the spoke head for added durability in high-stress areas. Cold-drawn from premium stainless steel, these spokes offer excellent strength and direct power transfer, while the sleek black stainless finish adds a durable touch.

Specifications:

• 54.5mm deep front profile with a 31.7mm external width provides low aerodynamic drag with wider 28mm tyres.
• 58mm deep rear profile with a 30mm external width to reduce weight in turbulent air.
• Lightweight rim layup strategy using T800 unidirectional carbon fibre with 3K weave reinforced spoke holes for ultimate wheelset performance.
• Manufactured from H_CYCLO rim technology to allow the rims to be ready to be recycled at the end of their life.
• Designed by HUNT’s in-house Engineering Team using Computational Fluid Dynamics (CFD) and then validated using wind tunnel testing.
• Aerodynamically optimised for a 28c tyre.
• The wide 22mm internal width is provides good tyre support and volume for excellent grip and low rolling resistance.
• Hooked 22mm internal profile allows a wide range of tyres from 25mm-50mm to be fitted including tubeless or clincher tyres in-line with ETRTO guidelines.
• H-Lock bead-seat up-kick for secure tyre fitment.
• 20 front | 24 rear (2 cross both sides).
• Pillar Wing 20 with aerofoil profile to reduce aero drag | triple butted 2.2/0.95-2.0mm to increase strength.
