Shutter Precision, who has been producing a broad range of affordable, high quality dynamo hubs since 2009, has joined forces with Cycle Monkey to develop a 150mm fat bike dynomo hub. Recognizing the growing trend of fat bikes along with the increasing number of people choosing to use their adaptability to veer well off the beaten path, Cycle Monkey and Shutter Precision used their combined knowledge to come up with a solution.
Charge past the break for more…
Cycle Monkey, who has a broad understanding of how these bikes are being used, helped bring Shutter Precision’s technology to fat bikes with the new SP-8X in 150mm. Though many think “snow” is all a fat bike is good for, many have taken to using them to explore well off the beaten path due to their ability to adapt to so many terrains. One challenge in building the fat bike version of the SP-8X was the big bike’s slower riding speeds and larger wheels compared to more standard bikes. The lower rotational speed of the hub makes it difficult to get full power output from a standard dynamo and causes the hub to have more resistance, so SP hub designed the wider SP-8X hub with custom magnets, windings, and hub shell to remedy this.
All SP hubs provide the industry standard 6 volt output from 3.0 or 2.4 watts, depending on model, which allows them to be used with the majority of dynamo-powered lights on the market, and the new SP-8X in 150mm width provides a dynamo option for the Rock Shox Bluto and Lauf Carbonara fat bike suspension forks as well as rigid forks from Surly, Salsa, and many others.
MSRP will be announced shortly, with availability for the 150mm hub scheduled for January.
