Meh, seems a bit like a marketing spin to me. His whole tire deconstructed idea is interesting, but doesn’t hold water to me. They end up with a casing, base rubber, and knobs on top (regardless of his explanation to the contrary).
What he describes is something of an “inverted or negative tread tire”, which is a real thing. There are a number of negative tread tires from the past and present, that are more like a mega-block with minimal cuts or reliefs (negative space). Here are just a couple of examples:
What they end with looks more like a medium block tread tire, that has more negative space than positive. It is a nearly standard checkerboard / chevron lug progression that is not exactly game changing to my eyes.
I do think their focus on surface area and lean is a good and interesting one. But I also question their handling abilities. Much of the comments read like a roadie trying to apply roadie corner skills in all conditions (tarmac and dirt), which is not appropriate for mixed surface riding, IMHO.
The dirt side in particular seems to indicate they are not applying bike/body separation to lean the bike more than the rider body. It just comes off as they are not cranking the bike over with a stable waist, which is common and necessary in the MTB and dirt world.
I can vouch for some real differences and improvement in tires with shoulder knobs when ripping down loose and tricky turns of dirt roads. I’ve had confidence inspired rips with perfect hooking up with side knob tires and white-knuckle death grip waiting for a “regular” round tire to find some level of grip despite extreme lean and weighting. Those several tires gave real differences in feedback and grip based on the knobs on the sides, despite being the same course and technique.
I just don’t fully agree with their take aways despite thinking they have some good considerations.
