Dynamo hub or axle?
So far the ambitious rider had to do without one or the other. The axle stiffens the suspension fork and allows a more precise positioning of the hub, which is particularly useful for disc brakes. More and more mountain bikers want to take advantage of a hub dynamo lighting system. No wonder that we saw an increased demand for a thru-axle hub dynamo.
For this, we had to change not only the axle, but also substantial parts of the generator. Result is a hub dynamo similar in looks, strength and electrical values to SON 28 disc, just with a thick "hole". Also, with 460 g the weight could be kept quite low.
The SON 28 15 disc (6-hole) is available since October 2012 in the colors silver, black and red anodized.
