HUNT SUPERDURA DYNAMO DISC WHEELSET
TRUE FREEDOM FROM CHARGING FOR YOUR BIKE-PACKING ADVENTURES, HASSLE FREE COMMUTING AND WINTER TRAINING

THE PURPOSE
Created for 'Josh' types (Ultra-Distance Heros) 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.

The HUNT SuperDura Dynamo wheelset is the result. It features all of the fine details you’d come to expect from us, including our proven wide tubeless asymmetric SuperDura rim, extra sealed and shielded 4 Season Disc rear hub, and a seriously durable high 32-spoke 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.

For the HUNT SuperDura Dynamo 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.

With the light off/unplugged (e.g. day light riding) the graph below shows that for the SONdelux there is less than half a watt extra rolling resistance compared to a high quality normal non-dynamo hub. For a bit of context; for 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 level of fitness.

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 are required to work with dynamo hubs. If you're not sure what will work properly, Handy Bikes can help.

Maximum tire pressure for this rim is 100psi when used with 25-28mm tires. Maximum tire pressures for other tire sizes: 30mm - 32mm do not exceed 70psi, 33mm do not exceed 50psi, 35-45mm do not exceed 45psi, 45-50mm do not exceed 40psi. 100 psi is more than enough for any rider on road.
