Thanks for the heads-up on the non-stepped seatpost.
I slipped a 700c front wheel and tire on the forks and it looks like it would work just fine.
I tried a 700c rear wheel and the axle has too large of a diameter to slide into the dropout slots.
I then tried the 27” wheels I have and those also have too large of an axle diameter.
So, what to do, grind the dropout slots open a little, or grind some flats into the axle ends (wouldn’t take much), or run steel on back and an alloy on front? ? ? I will have to get out the digital calipers this weekend and do some measuring.
