We've been working with Mason Progressive Cycles since our very first wheelset, and we're excited to announce the Search 29 Dynamo Disc, our fourth collaborative effort. The wheelset is designed to perfectly accompany Mason's new InSearchOf. Read More

'Covering huge distances and riding fast across every imaginable terrain is the territory of the radical new InSearchOf. The full custom Mason X Dedacciai steel tubeset gives incredible ride quality and feedback with multiple mounting points and huge clearance for high volume tires'

The Mason x HUNT Search 29 Dynamo Disc wheelset is the result. It features all of the fine details you’d come to expect from us, including our rough-ready Trail Wide MTB 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 weight of the dynamo hub, this wheelset is still lighter than many disc-brake wheels fitted to bikes as original equipment.

For the Mason x HUNT Search 29 Dynamo Disc wheelset, we collaborated once more with SON (Schmidt Original Nabendynamo). We have 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.

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.

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 SON 28) 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. daylight riding) the graph below shows that for the SON 28 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 160-300 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.

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