the forks are thicker inside just think of the threads starting when the tube is thick so when they put the threads in the fork tube wont get really thin like the original forks tub is 2x thicker than normal so when they thread the inside it will be the same thickness as normal forks and there still light
The threads don't make it weaker in any way. Hell they could put threads halfway down the fork where there's no pressure on them because of the headtube if they wanted to. And Doms right haha it's not like it's revolutionary it's just us finally catching up to the bike companies who have already done this. I've been waiting for this for a while now.
