Hunt has in the present day unveiled a trio of latest wheelsets amid a wider announcement surrounding its plans for environmental sustainability.
In quick, which means that alongside a company-wide dedication to fulfill sure sustainability targets, three of its hottest wheelsets have undergone a redesign that makes use of recycled supplies, much less resource-intensive manufacturing processes, sustainability-focused specification decisions and shorter transportation distances to cut back the environmental affect.
The trio of merchandise will kind the beginnings of the model’s Sustain vary, which is able to develop as extra wheelsets bear the identical course of.
The transfer sees Hunt use a framework set out by the Science Based Targets Initiative (SBTi), the collaborative group between the Carbon Disclosure Project, the United Nations Global Compact, World Resources Institute and the World Wide Fund for Nature. SBTi was based in 2015, and is about as much as present corporations with a clearly-defined path to cut back greenhouse fuel emissions in step with the Paris Agreement targets.
The three wheelsets that make up the Sustain assortment up to now embody the 42 Carbon Disc Ti, the Four Season All-Road Disc, and the Trail Wide 29.
42 Carbon Disc Ti
The 42 Carbon Disc Ti is a flexible all-rounder that may deal with on-road and off-road terrain. It boasts a 42mm depth, and its inner width of 22mm means it’s optimised for tyres between 25 and 35mm.
It is the one carbon fibre wheel to land within the new assortment up to now, and the brand new model can be made utilizing 10% recycled carbon fibre.

Interestingly, to fabricate the edges, Hunt will use a wax mould, reasonably than the same old throwaway EPS or silicone moulds or inflatable bladders. Rather than reduce out, the wax may be melted, then re-moulded and reused greater than 20 instances. The building can even use a novel resin switch moulding technique, reasonably than ‘pre-preg’ carbon fibre. This means the sheets may be saved at room temperature, saving power prices. It additionally means offcuts of carbon aren’t already impregnated with resin, which implies much less resin is used total, and the offcuts may be recycled.
The final touch to those wheels is a one-piece titanium freehub physique, which has the outboard half of the star ratchet moulded immediately into place. This makes it lighter, whereas additional lowering waste materials.
Four Season All-Road Disc & Trail Wide 29
A by-product of the unique Hunt wheel, the Four Season is an reasonably priced alloy wheel that sits 25mm deep, 22mm extensive internally, and can be geared toward combined terrain using with tyres between 25 and 35mm, although it may possibly fortunately accommodate tyres as extensive as 50mm.
Meanwhile the ultimate wheel to be given the Sustain remedy is the Trail Wide 29, a mountain bike wheel optimised for tyres between 2.2in and a pair of.6in extensive, due to its 30mm inner width. The Trail Wide 27.5 is not presently present process the identical remedy, however it’s a protected guess that it’s going to comply with.
Both are made utilizing 75% recycled aluminium. 30% is sourced from post-consumer recycling, corresponding to recycled cans. The remaining 45% is sourced from the commercial sector, which presents larger materials consistency, and consists of CNC shavings or off-cuts.
Notably, all three wheelsets are being given silver spokes and nipples, which Hunt says are extra environmentally pleasant than anodised black variations.
“While anodising alloy rims and hubs is critical to guard the floor from put on and enhance the longevity of the element, {the electrical} chemical coating course of used to colour-coat black spokes and brass spoke nipples presents no sensible or efficiency profit past aesthetics,” says the model. As a end result, it has opted to save lots of the power and chemical utilization required.
This choice is simply one of many steps that make up the broader firm initiative to hunt accreditation by the SBTi. As a part of this settlement, the corporate will publish an annual report, for which the primary will come on the finish of 2024.
The Science Based Targets Initiative
The dedication contains a number of phases, or scopes, which develop of their affect with every step. Scope 1 consists of direct emissions from sources owned by the corporate, corresponding to buildings, autos and tools. Scope 2 extends the requirement to oblique emissions, together with the impact of manufacturing of electrical energy that the corporate makes use of. The firm has dedicated to cut back these emissions by at the very least 50% by 2030.
Scope 3 goes additional once more, extending to your entire provide chain of Hunt’s merchandise, upstream and downstream, together with uncooked supplies, electrical energy utilized by Hunt’s suppliers, and end-of-life disposal. This finally includes getting all of Hunt’s suppliers and clients to a Scope 1 and Scope 2 degree, one thing which Hunt says it’s dedicated to doing, both by utilizing completely different suppliers or by working with current suppliers.
Alongside this, Hunt additionally says it’s dedicated to growing the serviceability and sturdiness of its merchandise, so has dedicated to sustaining inventory of all service elements for all wheels relationship again to 2015 in a bid to encourage riders to restore their wheels, reasonably than exchange them.
Hunt is now the newest in a line of manufacturers within the bike business to set out sustainability targets. Canyon introduced it had been verified by SBTi in February of this 12 months, whereas Ralf Bohle GmbH – the mum or dad firm of Schwalbe Tyres – dedicated to its personal local weather targets with SBTi again in 2022. Elsewhere, Trek, SRAM and REI every produce an everyday sustainability report, whereas Giant has laid out its ESG dedication and Bosch has been carbon impartial since 2020.
