Difference between SON 28 and SON hubs

Delux The SON 28 dynamo hub delivers its rated power of 3W from 15km/h, while the SON Delux reaches this power from 20km/h. The SON 28 dynamo hub is therefore recommended for applications requiring maximum power at the slowest speeds, making it the model of choice if you want to recharge appliances while riding.

The SON Delux dynamo hub is optimised to be as light as possible (by optimising the winding and not by compromising the strength of the body) and to offer the least possible rolling resistance. It therefore needs to spin faster to achieve the same power output, and is therefore ideal for cycling at higher speeds or for bikes with smaller-diameter wheels.

Compared to a conventional front hub, the loss of efficiency at 25 km/h is less than 1% for the SON Delux and around 1.2% for the SON 28.
