Define "new stuff."
I'd say that most of the stuff there was "used" but less than 25 years old. There were NOT a lot of 50 year old bikes or parts that I saw, though I didn't spend much time in the "used bike corral" either.
I picked up a gently used, sort-of ergonomic road saddle that's probably only a few years old -- it's the kind that a tool bag CLIPS INTO a specially designed slot in the back. buzzrocker13 picked up a set of Woodchipper-esque off-road drop bars and a set of 8 (?) speed bar-end shifters, neither with obvious wear but without any sort of packaging either, so all three of those are what? Ten years old or newer?
There were a handful of older balloon-tire bikes and parts, but for me it was mostly like
"the history of bicycling since the mid 1970's, as a 50 year old personally experienced it."
"I had one of these! And one of those...and WANTED to buy one of those early aero-bars but was getting into mountain biking instead...hey, remember these?! And when did THOSE come out? Okay, I wasn't really into road bikes by that point...."
So, yeah.
Newer stuff, mostly older than the bikes and parts that show up at the bike co-op, but also generally in better shape.
But, since admission and parking are free and relatively plentiful, it's probably worth a short drive -- based on the first and only one, I'D gladly drive a half hour to do it again, even if the event stayed the same size. If it was an hour away, on the far side of Dayton? Probably, if it wasn't snowing. TWO hours to Cincy or Cleveland? Ummm...maybe not.
