MASON x HUNT 650B AdventureDynamo Disc wheelset (24 deep / 25 wide) 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 extra 240g of the dynamo hub, this wheelset (at 1821g) is still lighter than many disc-brake wheels fitted to bikes as original equipment! The wheels are designed to work excellently with both clincher tyres and tubless tyres. 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 (11-12 mph with the SONDelux) just 4.6 watts of your rolling power is used. Of course the light is always available, so no realising you forgot to charge and having to abandon your ride.

SON DYNAMO

SONDELUX | 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 11-12mph. Even at 10mph, 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 395g (the SON28 weighs 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.

ADAPTABILITY

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 and 6 bolt adaptors included.

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.

RIM BED

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.

BEARINGS

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.

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.

FREEHUB BODY

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.

WEIGHT

The consequence of the fanatic attention to detail is incredible durability and a resulting low 1821g wheelset weight.
