<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>
MASON x HUNT 650B Adventure Dynamo Disc Wheelset
<h1>Rim Bed</h1><i>H-Lock tubeless-ready rim bed profile. H-Lock refers to our tubeless-ready rim bed profile. 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>

MASON x HUNT 650B Adventure Dynamo Disc Wheelset

19 Deep | 29 Wide Ext | 25 Wide Int | 1947g

Dynamo freedom, now available in 650B! Ready for your bike-packing adventures, hassle-free commuting, and winter training.

19 Deep | 29 Wide Ext | 25 Wide Int | 1947g

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 an ingenious idea, 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. Read More

The opportunity to open up your riding comes from bikes which have geometry designed to ride excellently with both 700c or 27.5" (650b) wheels. This combination works thanks to the extra volume in a 2" x 27.5” tire, providing an almost identical external tire diameter to a normal road sized 700c wheel with a 33mm tire, leaving the bike geo unchanged. What was needed was a bike that could accommodate the extra tire width, while still running road groupsets, geo and components. These bikes are increasing in popularity and availability continuously!

The MASON x HUNT 650B AdventureDynamo Disc wheelset is the result, featuring our proven wide tubeless asymmetric 650B AdventureSport rim, with our extra sealed and shielded 4Season Disc rear hub, and a seriously durable high 28 spoke count build (of Pillar's light and extremely strong triple-butted PSR spokes). Even with the 430g dynamo hub, this wheelset (at 1947g) is still lighter than many disc-brake wheels fitted to bikes as original equipment!

For the MASON x HUNT 650B AdventureDynamo Disc wheelset we collaborated with SON (Schmidt Original Nabendynamo), we had long been aware of just how highly regarded SON are for their durability and performance. Wilfred Schmidt is incredibly passionate about dynamos so our chats with him excited our inner geek. Wilfred and his team have been engineering their dynamo hubs in Germany since their first prototype 25 years ago.

SON dynamos are renowned for their market-leading efficiency. When your light is drawing power (light switched on), the efficiency of a SON hub is an impressive 65%, so at the German testing standard of 3 watts / 6-volt dynamo output (the rated output is achieved in the 700c (622)-wheel at approx. 16 km/h (SONdelux at 19 km/h), just 4.6 watts of your rolling power is used.

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.

SON Dynamo graph

The deep thought and detail that goes into every SONdynamo sits well with our philosophy to HUNT for improvements in even the smallest details. The connectors used by SON are a great example; they are universal spade connectors available from most electrical retailers/suppliers/hardware stores rather than a connector that is unique to the hub design. This means that if the connector is lost or damaged far from home finding parts will be a whole lot easier.

Please note:

These wheels are adaptable for 12mm and QR axles. They are not suitable for 15mm axles.

Dynamo specific AC power charging devices or lights (Exposure Revo) are required to work with dynamo hubs.

      SON28 | Highly efficient, faster and lower weight.

      Drop-bar road and adventure bikes are designed for going fast, whereas many dynamo hubs were designed for town bikes. The rapid advancement and incredible efficiency of LED lighting compared to older halogen bulbs has meant that lights such as the Exposure Revo (available as a package with these wheels - please click here) would run at its whopping 800 lumen output at just 10mph. SON realised that by using a smaller/lighter generator, they could reduce drag by an impressive 20% and still achieve the 3 watt / 6 volt output (800 lumens on the Revo light) at just 10mph. Even at 8mph, you will get upwards of 500 lumens from the Exposure Revo light! The super-fast SONdelux is the result of this innovative thinking... 20% better rolling resistance and lower weight, only 430g.

      5 Year Warranty (incl. Bearings)

      The unique SON Pressure Compensation System allows us to offer a you huge 5 year warranty on the SON Dynamo hubs including bearing wear.

      SON Pressure Compensation System

      All dynamos heat slightly during operation and then cool, the cooling of air in the hub body of most dynamo hubs can cause lowering air pressure inside the hub. This lower air pressure can lead to suction of water through the bearing seals significantly reducing the life of hub bearings. However, SON dynamos feature their unique Pressure Compensation System which consists of an air flow port on the axle cap and inside the axle (as shown below) and an air reservoir tube.

      Son28 Dynamo Hub on Hunt Bike Wheel

      SON Dynamo Pressure Compensation Port

      The SON Pressure Compensation System allows air pressure to be equalised, thus extending bearing life to a huge 50,000-100,000 kms. The tube (shown below) is long enough that water doesn't reach the end, and when the dynamo heats up again air pressure increases and any air and water is forced back out of the axle end of the tube preventing damage.

      Why only suitable for 12mm and QR, not 15mm?

      "We would like to offer a 15mm option on these Dynamo wheels. Dynamo wheels (whilst being able to adapt to QR with a sleeve) cannot be adapted between 12 and 15mm (unlike a normal hub) due to the hub caps needing to be fixed and cabled for the dynamo to operate, and 12mm forks will not accept a 15mm cap as they have a small ridge above the axle interface. The AdventureDynamo wheels can adapt to any other current axle standard on the market, you just need to let us know what are your requirements by filling in the simple form on the confirmation page after checkout. Of course we are looking at 15mm as an option in the future, but it would probably need to be 6-bolt to allow the larger ball bearings; ball bearing size is very small on 15mm dynamo axles if fitted inside a centre-lock disc mount diameter and around the larger dynamo axle thickness (needs space for wire to pass through the bearing inner diameter unlike a normal 15mm hub axle).

      Apologies to anyone who was hoping for a 15mm MASON x HUNT Dynamo option, it was a difficult decision to make for our first dynamo option, and we of course want to serve as many riders as possible. I hope this explains it a bit more, we would love to offer an option for you soon. Obviously since drop bar disc brake bikes are now becoming more stable in their standards hopefully these things will be simpler in future, here's hoping as it would probably make all our lives easier as riders. Thanks again and enjoy your riding, Tom Marchment (Hunt Bike Wheels | TheRiderFirm)

      "The best wheel award for 2018 goes to Hunt for making performance wheelsets with a hub dynamo. The Adventure Dynamo Disc is one option for 650B adventures, but their Search 29 Dynamo Disc mountain bikepacking wheels together with Mason Cycles are an equally solid option if you need a 700c/29er setup. Ride farther, charge you GPS during the day, and light the way at night – no batteries required!"

        SON28 | Highly efficient, faster and lower weight.

        Drop-bar road and adventure bikes are designed for going fast, whereas many dynamo hubs were designed for town bikes. The rapid advancement and incredible efficiency of LED lighting compared to older halogen bulbs has meant that lights such as the Exposure Revo (available as a package with these wheels - please click here) would run at its whopping 800 lumen output at just 10mph. SON realised that by using a smaller/lighter generator, they could reduce drag by an impressive 20% and still achieve the 3 watt / 6 volt output (800 lumens on the Revo light) at just 10mph. Even at 8mph, you will get upwards of 500 lumens from the Exposure Revo light! The super-fast SONdelux is the result of this innovative thinking... 20% better rolling resistance and lower weight, only 430g.

        5 Year Warranty (incl. Bearings)

        The unique SON Pressure Compensation System allows us to offer a you huge 5 year warranty on the SON Dynamo hubs including bearing wear.

        SON Pressure Compensation System

        All dynamos heat slightly during operation and then cool, the cooling of air in the hub body of most dynamo hubs can cause lowering air pressure inside the hub. This lower air pressure can lead to suction of water through the bearing seals significantly reducing the life of hub bearings. However, SON dynamos feature their unique Pressure Compensation System which consists of an air flow port on the axle cap and inside the axle (as shown below) and an air reservoir tube.

        SON Dynamo Pressure Compensation Port

        The SON Pressure Compensation System allows air pressure to be equalised, thus extending bearing life to a huge 50,000-100,000 kms. The tube (shown below) is long enough that water doesn't reach the end, and when the dynamo heats up again air pressure increases and any air and water is forced back out of the axle end of the tube preventing damage.

        Why only suitable for 12mm and QR, not 15mm?

        "We would like to offer a 15mm option on these Dynamo wheels. Dynamo wheels (whilst being able to adapt to QR with a sleeve) cannot be adapted between 12 and 15mm (unlike a normal hub) due to the hub caps needing to be fixed and cabled for the dynamo to operate, and 12mm forks will not accept a 15mm cap as they have a small ridge above the axle interface. The AdventureDynamo wheels can adapt to any other current axle standard on the market, you just need to let us know what are your requirements by filling in the simple form on the confirmation page after checkout. Of course we are looking at 15mm as an option in the future, but it would probably need to be 6-bolt to allow the larger ball bearings; ball bearing size is very small on 15mm dynamo axles if fitted inside a centre-lock disc mount diameter and around the larger dynamo axle thickness (needs space for wire to pass through the bearing inner diameter unlike a normal 15mm hub axle).

        Apologies to anyone who was hoping for a 15mm MASON x HUNT Dynamo option, it was a difficult decision to make for our first dynamo option, and we of course want to serve as many riders as possible. I hope this explains it a bit more, we would love to offer an option for you soon. Obviously since drop bar disc brake bikes are now becoming more stable in their standards hopefully these things will be simpler in future, here's hoping as it would probably make all our lives easier as riders. Thanks again and enjoy your riding, Tom Marchment (Hunt Bike Wheels | TheRiderFirm)

        Bikerumor Editor's Choice Award

        "The best wheel award for 2018 goes to Hunt for making performance wheelsets with a hub dynamo. The Adventure Dynamo Disc is one option for 650B adventures, but their Search 29 Dynamo Disc mountain bikepacking wheels together with Mason Cycles are an equally solid option if you need a 700c/29er setup. Ride farther, charge you GPS during the day, and light the way at night – no batteries required!"
