Nice!
Why did you go with this hub and not something like a QS205?
Are you using bike tires?

I am also finally making use of my stoba pack. It’s actually quite nicely put together. So I’ll try to keep it as is, just adding an xt60.

I got a crazy good deal on the wheelset, less than buying just the hub :yum:
using the tires they came with for now, gonna see how they are

Brakes installed, that was quite the macgyver rabbit hole, double post mount adapter to space the caliper closer to the rotor, and double rotor to move the rotor to the caliper. It works :yum:
