Pre-Uniglide Shimano chain standards...

Hi Everyone!

Did Shimano have a different chain/ spacing standard prior to Uniglide? Is Uniglide backward-compatible with Shimano chainrings from the '70s?

In a related question, how well would Uniglide chainrings work with, say- a SRAM 8-speed chain & HG cassette & shifting? A friend of mine has a set-up like this on his RB-1, and says it's non-optimal, but workable if he keeps the chain clean & well-oiled.

I'm Kinda curious about how well that could work; if a '70s Shimano crankset could be used with an otherwise modern drivetrain?

I've used a Dura Ace EX crank with Sugino chainrings and a Hyperglide 8spd cassette with no problems at all; however, that is not to say that it is equivalent to modern chainrings' shifting abilities.

FYI with this crank-cassette combo, I used Shimano 1056 DT shifters and a 1050 rear derailleur with a SRAM 8spd chain.

Prior to Uniglide, their chains were similar to Regina Extra in my view, Sedis was better.

My take on Uniglide:

I was given a sample freewheel and chain by Shimano to test.
I used it for nearly a month, and removed it before the test drive was complete.
The chain had stretched within 1,000 miles to the point of skipping.

I was not at the shop when the engineers picked it up, but they were bewildered I was told.

The chain did pick up the next cog well, but the outer plate design in my opinion was Designed to stretch.

Ultraglide and then Hyperglide were better.

Bikes are okay, I guess.

I tried one Uniglide for commuting when they came out and had similar results. Went back to Sedis. Uniglide was 1/2"x3/32" like other derailleur chains but had the bowed outer links that Shimano claimed made it shift better. Meh. I was using my Uniglide with a SunTour Perfect freewheel, so might not have had the full Shimano shifting experience. I do not recall Shimano chains pre-Uniglide.
