Dynamo Hub Through Axle
Given that touring and bikepacking is often conducted at speeds below 25kph 15mph the most powerful option 3w is necessary for charging usb devices and it s the best for low speed lighting too.
Dynamo hub through axle. The e thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed. After several iterations of computer aided structural simulations shutter precision was able to make a a 6v 3w dynamo hub with class leading efficiency at a claimed weight of just 420. There are three different power specifications for dynamo hubs. P 8x dynamo hub 6v3w for 646 716mm.
But with a dynamo hub there s a catch. Standard hubs with thru axles don t require the skewer to be as tight as it would need to be on a traditional hollow.

Technology should make life simpler and easier. An 8 mm thru axle system for the trekking hybrid hub and dynamo hub and a 12 mm thru axle system for the rear are also available. Thru axle kasai fs dynamo hubs are a bit more expensive 190 for either 6 bolt or centerlock disc but unfortunately it seems to only be available in a 15mm x 100mm axle configuration. Originally developed for the extreme demands on suspension forks and disc brakes of mountain bikes.
Hub dynamos for thru axles.
