That much change is huge, easily enough for a 1 MPH gain in average speed over 30 miles on a flat course.
It's a little mind blowing actually. I was all weight weenie all the time but now its clear that aero is really a thing.

(first post here after lurking and learning forever) -- Lol, I had same experience today. Went from 22.5 wide/ 24.5 deep Rol alloy wheels to non-disc DT Swiss PRC 1400 spline 35s (25 wide/ 35 deep, with GP 5000 tl tires) and was just completely blown away. I think there were a bunch of factors at play -- aero, stiffer rims, better hubs. Goddang, it was magic. Or witchcraft. Didn't love the braking, but I'll adjust.
