The Purpose _

The Purpose _

A lightweight, responsive and versatile gravel wheelset designed to meet the needs of the modern gravel rider and racer, made using H_Cyclo recyclable resin and carbon technology. Wide and light 40mm-deep hookless rims offer quick acceleration, aerodynamic efficiency and race-ready durability, optimized for modern wide gravel race tires. Laced with our quick-engaging H_Ratchet 40T DBL hubs, the complete wheelset weighs in just over 1400 grams.



Built to transform how your gravel bike performs on your fast and steep gravel rides or races.

KEY FEATURES_

Tubeless Design

40mm-deep and 30mm-wide external rim profile, featuring an ETRTO-compliant tubeless straight-sidewall rim with 25mm internal width, designed for modern gravel tubeless tire compatibility.

H_Cyclo

Fully recyclable thermoset epoxy resin technology that allows for the separation and re-use of both the carbon fiber material and resin components at end-of-life without creating waste solvents or pollutants. Race-ready rims that will never see the landfill: performance meets purpose.

H_Ratchet 40T DBL Hub

Dual-sided 40-tooth ratchet system offers 9-degree engagement and durability for loaded adventures, with all 40 teeth engaging simultaneously to handle high torque loads.

TECHNOLOGY _

Fully recyclable thermoset carbon technology with no performance compromise. 

H_Cyclo technology enables the recycling of both the carbon fiber materials and the epoxy resin used in the thermoset carbon fiber molding process, which is the most mature carbon fiber manufacturing process available for bicycle rims and components, generally yielding a higher strength-to-weight ratio when compared to other carbon production methods such as thermo-plastic resin systems. This may well change over time as technologies mature, but for now thermoset is the leader in strength-to-weight ratio for bicycle rims and frames.

Using a chemical solution called CleaVER, the carbon fibers and epoxy resin are separated using heat and agitation, so that both components can be re-used to create new (smaller format) carbon components without the by-products of waste solvents or pollutants. Secondary products can be constructed without the addition of virgin carbon fibers, significantly reducing the production emissions required. Originally created to enable the recycling of large format glass fiber wind turbine blades, the recyclable resin has no impact on the structural integrity or strength-to-weight ratio of the carbon layup, making the technology ideal for precision, high-performance rims. HUNT will cover the collection of product at end-of-life, making the process seamless and no-cost for riders, should their wheels become unusable in an accident or crash.

Tires Info
HUNT recommends a 35-50mm tire for best performance, tire widths between 29mm and 60mm are also safe to use.   Note: best performance is usually gained by using tire pressures lower than the maximum, you can see our blog post about this, read here.  Tubeless-ready for lower weight and rolling resistance.  Only use tires marked as compatible with hookless (TSS) rims.  You must not exceed the maximum tire pressure limits set out in the table below or the maximum limit set by your tire manufacturer if this is lower.

HIGH SPECIFICATION COMPONENTS _
H_Cyclo Rims

Fully recyclable and reusable epoxy resin technology, H_Cyclo, allows HUNT to recycle and reuse the carbon fiber from this wheelset. Utilizing this technology, end-of-life carbon composites undergo a process where the resin is separated from the fibers, allowing them to be utilized into new applications.

H_Ratchet 40T DBL Hub

HUNT H_Ratchet DBL, 40T dual sided ratchet system, 9-degree engagement.

HUNT 40 Carbon Gravel Race H_Cyclo Front Hub
Precision Bearings

Double sealed stainless steel cartridge bearings offer smooth, reliable service with low friction.
Freehub Body

Featuring HUNT’s H_Ratchet double-sided system (with two floating ratchet rings), with a 40t ratchet ring resulting in just 9˚ engagement. The freehub benefits from H_Ceramik anti-bite coating to ensure maximum durability. Durability is a theme for HUNT, and so all our freehub bodies have to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.
