…but I can’t see how it couldn’t have been done before…
I was riding my 28" down the street earlier today and I started thinking of tricks that I could do on such a larger wheel than I’ve been accostomed to. I can wheelwalk it, 1ft ww, stomach-on-seat hand ww, and, now, after about 10 attempts, I can loosen the seatpost, spin the seat 360°, and re-tighten the seatpost.*
I have never, in all of the gigs’ worth of videos I’ve watched and saved, seen anybody do this.
That is pretty cool, especially if you can do it really fast (relatively). It is a little harder for those of us that don’t have quick release seats, since I would have to take an allen wrench, but maybe I will figure out a way to try that.
