SON 28 12 110 6-Bolt

SON's all-purpose hub dynamo for 12 mm Boost forks with 6-bolt rotors.

Built for adventure, bikepacking and gravel bikes with 12 × 110 mm Boost thru-axles. The symmetrical, wide flange spacing builds a stiff, strong wheel, and the SON 28 generator gives plenty of light even at walking pace, with enough output left over to charge a phone or GPS through a USB charger.

• Symmetrical, wide flange spacing for a stiff, strong wheel
• Robust 6-bolt disc rotor mount
• Sealed, maintenance-free bearings
• Made in Germany by Wilfried Schmidt Maschinenbau, 5-year guarantee

• Axle: 12 × 110 mm thru-axle (Boost)

Check your fork: this hub is for 12 × 110 mm Boost forks. For standard 12 × 100 mm thru-axle forks, choose the SON 28 12 6-bolt instead.

Tip: Tighten the thru-axle firmly. If it's loose, the hub axle can turn in the fork when the light is on and strain the wires.
