Hunt Reinvigorates 650B Gravel Wheelset with H_Core Technology
Hunt has recently revitalized its 650B Adventure Carbon Disc wheelset, integrating advanced H_Core carbon reinforcement. This development is poised to cater to the growing demands of gravel riders who seek enhanced resilience and the flexibility to equip larger tires for challenging off-road conditions and extended journeys. The company asserts that the updated wheelset, despite its robust construction, maintains an impressive lightness, tipping the scales at a mere 1,390 grams.
Hunt's Innovative H_Core Technology Enhances Gravel Cycling Experience
On a crisp Friday, September 11, 2026, Hunt, a prominent British cycling brand, introduced its significantly upgraded 650B Adventure Carbon Disc wheelset. This latest iteration proudly features the brand's proprietary H_Core carbon reinforcement technology, previously seen in other successful models. The integration of H_Core is a direct response to the evolving needs of gravel cyclists, particularly those who frequently navigate rugged landscapes and embark on multi-day adventures with fully loaded bikes.
The core innovation, H_Core, involves the strategic placement of pultruded carbon within the rim sidewalls. This meticulous process, where composite material is drawn through a heated die, effectively minimizes porosity in critical stress areas. Consequently, the wheels boast substantially improved impact resistance without adding unnecessary bulk. Complementing this robust rim design is Hunt's rapid-engaging H_Ratchet 36 SGL Hubset and durable brass nipples, culminating in a resilient yet lightweight package.
Hunt advocates for the continued relevance of 650B wheels, proposing them as a viable solution for cyclists looking to install wider tires without the need for an entirely new bike. The brand highlights the similar outer diameter between 700C tires (40-45mm) and 650B tires (2.0-2.2in), suggesting that a swap in wheelsets will not significantly alter a bike's inherent geometry. This provides a cost-effective avenue for older gravel bikes to accommodate more voluminous rubber, contingent on adequate frame clearance.
Beyond the H_Core inserts, the 650B Adventure Carbon Disc wheels incorporate preformed carbon angular spoke patches. These are specifically engineered to mitigate spoke pull-through, a common issue where spokes can damage the rim at the spoke hole. The rims themselves feature a 25mm depth, optimized for both compliance and resilience, with an internal width of 27mm and an external width of 32mm. Designed as hookless and optimized for tires up to 60mm (2.35in) wide, these wheels are clearly positioned for high-volume gravel and adventure cycling.
The wheelset is built around Hunt’s H_Ratchet 36 SGL hubset, featuring a 36-tooth ratchet drive system at the rear that ensures a quick 10-degree engagement when pedaling commences. The wheels are expertly laced with 28 Sapim D-Light double-butted spokes, both front and rear, and finished with brass nipples, contributing to the overall claimed weight of 1,390g. Priced at £949 for the pair, these wheels are available for pre-order and are expected to be in stock by the end of September.
The latest advancements from Hunt signify a renewed focus on enhancing the riding experience for gravel enthusiasts. By prioritizing impact resistance and offering a practical solution for tire versatility, Hunt not only demonstrates its commitment to innovation but also underscores the enduring potential of the 650B wheel format. This release encourages cyclists to rethink their equipment choices, proving that cutting-edge technology can extend the life and capability of existing gravel bikes. It also reinforces the idea that strategic component upgrades can yield significant performance benefits, inviting riders to explore more adventurous terrains with confidence and comfort.
