The Purpose _

The Purpose _

The second MASON x HUNT collaboration, bringing go-anywhere capabilities to bikes like the fast, fun and highly-versatile MasonCycles.cc Bokeh. The new breed of Adventure Sport focused bikes have the ability and attitude for those fun trail thrashes and bike-packing adventures, whilst not compromising anything for fast-far road days.

Tyres Info
HUNT recommends a 40mm tyre for best performance, tyre widths between 29mm and 64mm are also safe to use.   Note: best performance is usually gained by using tyre pressures lower than the maximum, you can see our blog post about this, read here.  Tubeless-ready for lower weight and rolling resistance.  You must not exceed the maximum tyre pressure limits set out in the table below or the maximum limit set by your tyre manufacturer if this is lower.

HIGH SPECIFICATION COMPONENTS _

Rims

Strong and light 6066-T6 (+34% tensile strength vs 6061-T6) heat-treated rim features an asymmetric shape which is inverted from front to rear to provide balanced higher spoke tensions meaning your spokes stay tight for longer. The profile is disc-specific, allowing higher-strength to weight as no reinforcement is required for a braking surface. The extra wide rim at 29mm (25mm int) creates a great tyre profile with wider 35c+ tyres, giving excellent grip and lower rolling resistance.

SPOKES

We chose the top-of-the-range Pillar Spoke Re-enforcement PSR XTRA models. These butted blade aero spokes are lighter and provide a greater degree of elasticity to maintain tensions and add fatigue resistance. These PSR J-bend spokes feature the 2.2 width at the spoke head providing more material in this high stress area. The nipples come with a square head so you can achieve precise tensioning. Combining these components well is key which is why all Hunt wheels are hand-built.

Nipples

To accompany these high-end spokes we selected brass nipples for our Hunt 4Season wheels. Brass is strong and corrosion resistant plus it has self-lubricating properties to prevent issues that can arise from grit salt on the winter roads corroding the fine threads in alloy nipples. As well as the standard square body we chose nipples with a hex head so you can achieve precise tensioning.

Freehub Body

Durability is a theme for HUNT, as time and money you spend fixing is time and money you cannot spend riding or upgrading your bikes. This is especially important for a 4 Season bike you use regularly in harsh conditions. As a result, the freehub features our H_CERAMIK coating to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.

Bearings

The heart of any wheel. Investing in them makes huge sense. We use high-grade precision sealed cartridge bearings with proprietary waterproof grease specially selected for even the worst weather.

Rim Bed

H_LOCK tubeless-ready rim bed profile. H_LOCK is our tubeless-ready rim bed profile, with up-kicks to the shoulders of the tubeless steps. This helps to create a great rim-well seal for first installation and easy sealing of tubeless tyres. The H_LOCK profile also locks the beads in place more securely once seated. This is especially important when running lower pressures off road.
