We also discerned a thicker casing, with some of the beefiest sidewalls we have felt. The information provided here does state that beyond the folding Aramid bead, there is a “Kevlar” belt under the tread for flat protection. Origin 8 states that these have a “high thread count for improved ride quality”, but we are not told what that is exactly. Now these tread patterns are certainly Duro’s, but unlike the models they showed at Interbike 2009, (shown at the bottom of our report here), these seem to be a bit different in the make up of the casing. In fact, in the case of the Origin 8 “Captiv8er” model, Duro’s original model name for the tire, “Gremlin”, can be plainly seen embossed into the casing! The Agit8er proved to be a bit more mysterious, but with a little sleuthing, I also discovered that it is actually a Duro Miner 29er. Well, these Origin 8 tires are actually made by this company, and the evidence of this is not hidden at all. They had been working on others tires for years. as a tire maker under under their own name. The “Origin” Of The Origin 8 Tires: Back at Interbike 2009, we ran across a tire maker that was looking to break into the 29″er market and into the U.S. Let’s take a look at the tires background first……… Now I will break down the two tires with specs and weights, and I will also give you some background on them. Recently we introduced the Origin 8 Captiv8er and the Agit8er treads to you.
