I recently picked up a Sentinel Horizon frame. The headbadge says "Sentinel" on it, and has a sort-of toy soldier logo on it. I did a search and found a few threads, someone thinks that Sentinel might have been a house brand for Supergo at some time.

The frame is steel, the label says "tubelite butted", it is very stiff and lighter than I expected it to be. It came with cottered cranks and a mix of components, but I'm not sure which of it is original. It was meant for 27" rims, and even with those it would require a long brake reach, and the wheelbase is long as well, leading me to think it may have been a touring frame, rather than a racing frame. It also has randonneur bars with the upswept parts at the ends.

If anyone has any information about it I'd be interested to hear it, I have had a lot of trouble coming up with any!

No one knows?

Perhaps some photos?

I remember the brand name. I believe it is either a Japanese or Taiwanese manufactured bike from the mid 80's. I don't believe that it had anything to do with the Supergo brand, but perhaps it might have been associated with Royce-Union bikes of Long Island, New York. Others may correct me on this.

I too have a Sentinel Horizon. After checking the threads and a lot of goggle-ing it seems like it's a late 1970's California built bicycle. Unfortunately it was probably a cheap entry-level road set up. Mine came to me with ornate lugs and a metallic (and badly chipped) orange paint job which I am currently repainting. It also had a bunch of Shimano components including cottered cranks with the Shimano Front-freewheel system on it. Though it's on the cheaper side of the spectrum I really like the frame. It's not too heavy, nice and stiff, and has those sweet lugs on it.

Here's a picture of mine before I tore it down and started painting. I'll try to post a picture after the build is complete but I might be having too much fun riding it to remember.

I had one, well part of one, last year but it needed too much work and I just gave it away. I would agree that the frame on the one I had seemed lighter than I expected it be, which made me pause for a minute before I passed it on. I have seen a few come through the local bike coop. They looked like serviceable riders, but I never saw any that looked even remotely high end.

Oh man, rush of memories flooding back. I had a Sentinel Sophomore in silver and black back in the late 70's/early 80's when I was in junior high school. I vaguely recall getting it at a car dealership in Cleveland (Rick Case Honda). I had to constantly fiddle with the derailers to get them to shift correctly. Despite being decidedly unsophisticated by today's standards, I credit this bike with getting me interested in cycling. I put a ton of miles on that thing, riding everywhere (and without a helmet). I got so many flats that I finally put on solid racing tires. Made the ride very harsh, but I could ride though glass!

As suggested earlier, Sentinel were manufactured in California. The 'tubelite butted" sticker implies boom and an upper, entry level model. True touring frames of this era typically used plain gauge CrMo frames, so it is more likely a sports/touring model.

"Stiiff and lighter than expected" is a most appropriate description given the tubeset. It is indeed lighter than the your typical entry level, hi-tensile steel frame, though heavier than a butted, CrMo set. It would also be stiff, despite a relatively long wheelbase and what are probably slack angles.
