If you have two bikes with different hub axle specs that would benefit from a SON hub dynamo setup but don’t want to invest in two new wheels, then SON has a nifty new component you might be interested in. This nifty axle slides into a thru-axle SON hub and allows you to run a 9mm QR. The new SON 12 mm Thru-Axle Adapter is $23 and in stock now at Compass’ Web Shop.
