Lightweight, durable and ready for year-round use, the Hunt Mason 4Season Disc Wheelset was produced in collaboration with Mason Cycles to fill a gap in the market for performance specced wheels suitable for four season use. For use on disc road and cyclocross bikes, these wheels are packed with performance technology for exceptional speed and acceleration.

Hunt Mason 4 Season Disc Wheelset

The Hunt Mason 4Season Disc Wheelset is the outcome of a project between Hunt and Dom Mason of Mason Cycles to produce a wheel with spec suitable for a performance bike used in all weather conditions. These wheels have had fantastic reviews from some of the most respected publications and websites and are lightweight at just 1585g for the set so acceleration and climbing are hugely improved over many stock wheels.

There is an asymmetric shape to the 6061-T6 heat-treated welded rim that is inverted from front to rear. This results in higher spoke tensions making these an extremely durable wheel build and as no reinforcement is required for the braking surface this allows for a higher strength to weight ratio. The 23mm external width (17mm internal) is ideal to get a great tyre profile with wider 25mm - 32mm tyres for lower rolling resistance and better grip in the corners, and cross tyres up to 45c can be fitted.

Top-of-the-range Pillar Spoke Re-enforcement (PSR) triple butted spokes have been used, as butted spokes reduce weight and have increased elasticity, meaning spokes will retain their tension for longer. The 2.2 width at the spoke head, an area of high stress, ensures reinforcement where it is required most. J-bend spokes are easily replaceable and they are two-cross laced to handle braking forces. Strong and corrosion-resistant brass nipples are self-lubricating and have a hex head for simple and precise tensioning. All Hunt wheel are hand-built with exceptional attention to detail.

The bearings are high-grade sealed cartridge bearings from the Japanese experts at EZO and the freehub bodies have Steel Spline Insert re-enforcements to provide excellent durability against cassette sprocket damage; especially important as these are wheels designed for all seasons.

These wheels are future-proof, so when technology changes you won't need to buy new wheels. 12mm adaptors are included to convert the front QR hub axle to thru axle and it's possible to buy 9mm and 25mm adaptors separately. The rear hub can be adapted to 12-135/142 and centre-lock hubs and 6 bolt adapters are included for Shimano hydraulic brakes.

The wheels are tubeless ready but work just as well with clinchers and tubes. The H-Lock tubeless-ready rim bed profile has up-kicks to the shoulders of the tubeless steps to create a great rim-well seal for first installation and easy sealing of tubeless tyres. This profile also ensures the beads are locked in more securely once seated - especially important for the lower pressures used off-road.

The higher braking forces from disc brakes require a more securely fitting skewer and the internal cam quick-release skewers are ideal. They also keep everything running smoothly even in the worst conditions, preventing dirt entering the cam faces. Being stainless steel, these skewers won't rust.
