I don’t think they were necessarily “Grab ONs”. It’s hard to tell from ad copy from the time, although Grab Ons would have been available at that time (they have been in business since1973). Grab Ons are certainly still available. I think ESIs and Wolftooth are a bit better…and I’ve used and liked Grab Ons or decades.
