I also have some Pub 650b rims that can go with this. They’re hookless 27mm internal, and I have a set of 28h and 32h. Would let go cheap along with if you’re interested.
(When I bought the e-bike I thought, “this kills the HG for me.” But what happened was I fell in love with upright, swept bar, front loaded position in a way I did not with rando. Riding home today I thought that it’d be fun to build a better fitting version of the ebike. Realized I already owned that bike.)
