Original EZ Jive Handle Tentacles grips from Neal Enterprises.
I have no way of knowing the exact year these were made, however we purchased them from directly from Neal Enterprises and they have confirmed they have not been made in 20+ years.
Comes packaged in the original sealed bag with silver/black Jive Nuts donuts and bar ends (that go under the grips to keep your bars from wearing through the ends of the grips. Keep in mind these are 20+ years old and the donuts don't age well. If the ones you receive are usable, great! But if they're not, they are not guaranteed to be usable (but the grips are).
MADE IN THE USA
Overall length is 140mm
These fit standard 7/8" (22.2mm) handlebars
