The SON 28 Boost Dynamo Hub is built for riders who demand reliable power generation on mountain, bikepacking, and adventure rides. Designed around the 15 mm thru-axle and 110 mm Boost spacing standard, it delivers dependable lighting performance even at lower speeds — ideal for technical terrain, steep climbs, and loaded touring setups. Using the same proven internals as Schmidt’s renowned SON 28 hub, it prioritizes consistent output and durability for all-condition riding.
Compared to the SONdelux, the SON 28 creates slightly more resistance, but rewards riders with stronger light output at slow speeds where it matters most off-road. The widely spaced flanges make it easy to build an exceptionally strong and stable wheel, perfectly suited for rough trails and demanding expeditions. Finished in anodized black and made in Germany, this hub combines premium craftsmanship with long-term reliability backed by a 5-year warranty.
For best performance, ensure your thru-axle is properly lubricated and tightened. A loose axle can allow the hub axle to rotate inside the fork when the lights are engaged, potentially damaging the connectors.
