The SON 29 S packs more magnets into a smaller hub shell than the 28.
This means the same power output at lower speeds, which is perfect for off-road riding.
The magnets tuck neatly behind your brake rotor and it barely even looks like a dynamo hub!

Fits 12x100 thru-axle. 32 holes for 32 spokes. Made for straight-pull spokes, not J-bend.

Approximately 400g.
