MASON x HUNT 650B Adventure Dynamo Disc Wheelset
<h1>Bearings</h1><i>Bearings are the heart of any wheel and investing in them makes huge sense so we went to Japanese bearing experts EZO and invested extra to spec their high-grade precision sealed cartridge bearings in our full range.</i>
<h1>Nipples</h1><i>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.</i>
<h1>Spokes</h1><i>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.</i>
<h1>Freehub Body</h1><i>Durability is a theme for Hunt wheels 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 4Season bike you use regularly in harsh conditions. As a result all our freehub bodies have Steel Spline Insert re-enforcements to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.</i>
<h1>Rim Profile</h1>

With up-kicks to the rim bed shoulders, tubeless installation is made easy, thanks to a great rim bed seal. The H-Lock profile also locks the beads in place more securely once seated. This is especially important when running lower pressures off road.</i>
<h1>Adaptability</h1><i>Our wheels are seriously future-proof. We can adapt your wheels to any current axle standard on the market (no 15mm on Dynamo hubs), you just need to let us know what are your requirements by filling in the simple form on the confirmation page after checkout. As Shimano hydraulic brakes are appearing on many new bikes, we wanted riders to have the option so we went even more adaptable with centre-lock hubs.</i>
<h1>Tyres</h1><i>At HUNT, we enjoy the puncture resistance and grip benefits of tubeless on our every-day rides so we wanted to allow our customers the same option. Of course, all of our tubeless-ready wheels are designed to work perfectly with clincher tyres and inner tubes too.</i>

The Purpose _

<h1>Tyres</h1><i>At HUNT, we enjoy the puncture resistance and grip benefits of tubeless on our every-day rides so we wanted to allow our customers the same option. Of course, all of our tubeless-ready wheels are designed to work perfectly with clincher tyres and inner tubes too.</i>

The Purpose _

The 650b version of our highly-rated HUNT Superdura Dynamo Disc, created for 'Josh' types (ultra-endurance heroes), but also enjoyed by 'us' types (a bit less super-human, but still want convenience when commuting, training and road/off-road bike-packing).

A dynamo hub is a small coil of copper wire that spins inside a group of magnets to produce electricity, effectively it is an electric motor in reverse. You can then connect up electric devices such as lights, and never need to worry about having to abandon your ride due to lack of light. Following a large number of requests for a dynamo wheelset, our HUNT began for a lightweight and durable wheelset that provides you with freedom from constant charging of lights for your on and off-road bike-pack adventures, fast commuting and daily winter training.

KEY FEATURES_

<h1>Adaptability</h1><i>Our wheels are seriously future-proof. We can adapt your wheels to any current axle standard on the market (no 15mm on Dynamo hubs), you just need to let us know what are your requirements by filling in the simple form on the confirmation page after checkout. As Shimano hydraulic brakes are appearing on many new bikes, we wanted riders to have the option so we went even more adaptable with centre-lock hubs.</i>

Rims 

6066-T6 (+34% tensile strength vs 6061-T6) heat-treated. Tubeless-ready. Disc-specific. Asymmetric for balanced spoke tensions and a highly durable wheel build. 19mm deep. 25mm wide (internal) ETRTO 584x25. H-Lock bead-seat for easy and secure tubeless installation.

<h1>Bearings</h1><i>Bearings are the heart of any wheel and investing in them makes huge sense so we went to Japanese bearing experts EZO and invested extra to spec their high-grade precision sealed cartridge bearings in our full range.</i>

Dynamo Front Hub

SON28 with adaptable axles. 3 watt / 6 volt output at 16 km/kmh tested to German standard K687 for output requirement.

<h1>Freehub Body</h1><i>Durability is a theme for Hunt wheels 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 4Season bike you use regularly in harsh conditions. As a result all our freehub bodies have Steel Spline Insert re-enforcements to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.</i>

Hubs

HUNT 4 Season Disc J-bend spoke hubs with extra bearing shielding. 10 degree FastEngage 4-pawl freehub, with H_CERAMIK coating for enhanced durability. Centre-lock disc mount. Please note: If you require a 6 bolt adaptor you can purchase separately here

TECHNOLOGY _

With the light off/unplugged (e.g. daylight riding), the graph below shows that for the SON28, there is half a watt extra rolling resistance compared to a high quality normal non-dynamo hub. For a bit of context, a 1-hour commute fast training ride, as very amateur cyclists here at HUNT, we would expect to produce somewhere between 160-250 watts average depending on our weight and fitness. SON 28 is designed for high power output at low speed, so a lot of electricity for lights or for powering charging devices even when cycling slowly, a benefit that you will notice more on our 650b wheelset.

Tyres Info
HUNT recommends a 35 to 45mm 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.
