15mm Thru-Axle version of the SON 28 dynamo hub, with 110mm BOOST spacing.

The SON 28 has been specifically designed for high power output at lower speeds, when compared to the SONdelux hub.

This makes it perfect for offroading, gravel riding and bikepacking, where you still need great illumination and power to charge devices, even when fully loaded or going uphill.

With the SON Pressure Compensation System (PCS), the changes in internal operating temperature that would usually cause water to be pulled in to the bearings are mitigated.

Coupled with SKF double-sided sealed bearings, this gives SON the confidence to offer a 5 year warranty on the hub.

The SON 28 hub use standard 4.8mm spade connectors.

A perfrect partner to the Exposure Revo Dynamo Headlight.

We are able to hand-build these hubs into high quality wheels, using DT Swiss rims and spokes. Please contact us to find out more.

Please note: Not all colour / spoke count combinations are manufactured by SON, therefore some will not be available to purchase.

Our SON hubs may take 5-10 days to arrive.
