Shutter Precision SL-9 disc Centerlock dynamo hub
Ultraslim dynamo hub
Innovation is all about making self-breakthrough. Undoubtedly, the previous SP 8 series had established many new records in the field of dynamos, in terms of its size, weight, and efficiency. However, further advancement has always been the goal. As a result, SP 9 series has now successfully challenged the 8 series by achieving unprecedented dynamo characteristics. The SP 9 series, the ULTRASLIM dynamos, presents future technology and is able to provide cyclists with the best dynamo performance.
The 9 series has demonstrated an enormous improvement from the preceding series. It is innovative in the sense that it is extremely light with an outstanding performance that will certainly surprise you.
Specification - A new dimension of riding comfort
Every detail has been meticulously considered to accomplish such an enhancement. The premium dynamo construction offers not only a new dimension of riding comfort, but also a dynamic force inside the hub. In addition to its low resistance and ultraslim size, this new series is unbelievably light in weight and incredible efficient.
The unique aerodynamic shape of the hub has been optimized to a golf size, while attaining an unprecedented weight only 299g. All models included in the 9 series are related to the number of 9, especially in regard to weight. For example, SV-9-F is for OLD74mm with a weight of only 299g, and SV-9 is for OLD100mm with a weight only 309g.
