I pulled the Sram d7 dynohub (it vibrates and hums when I get much above 15mph) from the kit bike and replaced it with the last spare dynohub in my bike mess (a Shimano DH-T4000, which is a 1.5w unit like all of the 1n70’s I’ve got laced into wheels here. It’s lagniappe that it’s silver(ish) instead of black and makes the wheelset more matchy-matchy, but more importantly it doesn’t vibrate nearly as much as the d7 does.
