Anyone have any knowledge about this event? The bicycles they used? The disc brake system shown?

That is just dripping in awesomesauce! Like everything else from the 70s, it would be much better enjoyed while stoned.
OK, they were rotten, heavy bikes, but still, riding in fully supported co-ed group all the way across the country? Wish I could say that's how I spent my summer vacation. They even had a black dude riding, so, hip and racially integrated. Which was a new thing back then. If they'd made it five years later, they would have included an Asian woman and a Native American guy, too.

I guess they worked OK, but not good enough to replace caliper brakes on most bikes.....
I'm sure those kids went through ll sorts of "dramas" along the way, which always happens when you get all different sorts of people together for an extended time doing stressful activities. But then, those were still wild/free times and anything could have happened along those 3000+ miles, if you know what I mean...

It was a time when diversity was represented by the inclusion of one person of color.
I just wonder who JCPenney's thought would be the audience for this effort.... it must have been somewhat expensive to pay 12 riders and sag support, all for a fifteen minute piece of film. A film that doesn't really do much selling of the bikes or brakes or clothing or nothing.

Disc brakes look like a set I took off a junked.....

I also think it was Shimano.
What I do remember and why I gave it away was that it weighed a ton! Well, maybe not a ton but probably l or 2 pounds! And it didn't stop any better than the calipers.
Good idea, poor execution.

Don't forget it was the bike boom! I was 15 at the time, living in Canada and wishing I could ride *my* overweight department store bike (at least it was a Chiorda) on the great American tour. It was covered heavily in various media so not just a 15 minute film. And bikes were being sold by the millions so lots of interest.
On the disk brake - it was indeed heavy and even though we rode entry level bikes we dreamed of (and eventually did get) the lightweight bikes we know and love now. They were expensive too, so no one except an OEM would bother fitting them.

Bikecentennial (starting a year after in 1976) has some internet chatter, but nothing about the "Great American Bicycle Tour".
... and I assume you mean all bikes, not just this JCPenney's badge engineered chrome Huffy with a Shimano disk brake option. I have never seen a seventies Shimano disk brake, and I worked at a bicycle shop in the eighties where a lot of seventies bikes were constantly coming in for repairs. Not a one.
There is some info on the brakes... as others have recollected, they were "heavy". But, others noted (maybe not on this site, but on other sites) that the brakes did perform okay, though maybe not in the revolutionary way that Shimano was hoping they would. Or, maybe it was gimmick, and thus came and went as other gimmicks do. Seems odd that the technology came and went so quickly, only to resurface decades later, in the vein of "new and better".

Those were Huffy bicycles and think the whole point of the ride was to advertise those "state of the art" disc brakes. Had to be a full support ride as you can tell by the way they were dressed.

I owned one of those bikes! It went to college with me and was great as a campus bike. The disc brake's improvement was stopping the bike with wet, steel wheels - and it did work better than prayer, which was the alternative. Dry, it was somewhat less effective than the Dia Compe center pull used on the front. It also had the freewheel bearing on the crank. The chain moved whenever the wheel was turning. That was actually pretty neat for shifting without pedaling.
Anyway, I remember it fondly.
It was a time retailers wanted differentiation to stand out and it worked on me when I was 13. I remember Sears or Montgomery Wards had hydralic rim brakes - both controlled by one lever! Good times!

I remember this event being advertised, maybe in Bicycling magazine.
But by then I'd already done my tour and couldn't see myself riding clear across the country.
Fun video.

Back then I had just gotten married, started a job and career, and bought a house. I also wanted to cross the country by bicycle but that wasn't in the realm.

I have a Kabuki with one of those Shimano disc brakes. It is slightly better than dragging your feet on the ground. The pads are rubber! Why on Earth would you put this thing on a bike? Most braking is done on the front which has a trusty Dia-Compe single pivot caliper. It must have just been for the techno-bling factor.

I had never even seen a bicycle helmet until I went off to college in fall of '76. My roommate had one of the original Bell mushroom helmets - actually his second, since his first helmet got destroyed in a car/bike crash and probably saved his life. He always wore his helmet. It wasn't until I rode TOSRV '77 that I wore a helmet - a Skid Lid that someone had left behind at our club-sponsored Century ride the week before.
Gloves? Yeah, I had the crochet-backed things from Bike Warehouse (pre-nashbar), and I still get that same style when I can find them.
I never had padded shorts back then, so yes, I rode in 'tennis gear', complete with the ubiquitous three-stripe tube socks! I also wore the 'warm-up' style sweatpants, zippered jacket with the stripe on the sleeve and legs... and my beloved Puma Road Runner shoes.
So yes, cycling has evolved a bit over the past 40 years!!! Bikes, clothing and 'gear'.

I have a version of a rear Shimano disk brake. It is different than those pictured in the film though. I still have the bike frame - a MASA 12 high tensile with special braze-ons for the brake. The rotor was not ventilated, and was actuated by a standard lever. I cannot find the rear wheel, but as I recall the brake side of the rear wheel had reverse thread for the rotor and RH thread for the rotor locknut.

My graduating year!! Too cool. I never knew of this tour. As a teen, safety was never on my mind.
