Hey, good stuff!

The LED lights of the last few years have returned the classic 6V Sturmey-Archer Dynohubs (1945-1983) to the category of useful devices. But - and it's a big but - with their chrome-plated steel hub shells, they're breathtakingly heavy, even compared to modern dynamo hubs.

Fun fact: Tommy Godwin used an earlier model Sturmey-Archer Dynohub while setting his "most distance covered in a calendar year" (1939) world record: 75,065 miles!
