first ride into work this morning on the Corbin seat. My butt started tingling about 20 minutes into the ride. its definitely HARD, and it definitely has a position it wants you to sit in. about the end of the ride, maybe 35 minutes in, I could definitely sense that the seat was molding to my butt, and the tingles were gone. Just like my Mustang seat on my cruiser, definitely feeling good about this.
I'm going to have to adjust the rear brackets as I've noticed a little give in the front tongue... the rear brackets are keyholed, so you can adjust them back and forth, but the keyhole has the narrow side going towards the front, which I think should be reversed, so you can wedge the seat further forward, and then tighten the bolts down instead of needing a washer to keep the nut from popping out of the big round keyhole. my 2 cents.
