I’m suprised…I would have thought that the smaller wheel would be better.
My 28 is a Sun, all stock except for the KH seat.
my 24 is a 70s Schwinn with a KH seat and cotterless cranks and a 2.1 inch tire.
I can hope about 8 or 9 inches high with the Schwinn, and 11 with the 28" Sun.
I think the Sun is lighter, but I haven’t measured so I’m not sure.
Makes me wonder if I had a 20-inch really light uni, if I might actually not suck at hopping…
