Apart from the fact that I can see the majority of 'decent' forks moving to bolt-thru in the future (a combination of easier stiffness and product liability), it means that I can run a bit more sag and have the benefit of a sorted front end that won't deflect.
When I took my XTC from 80mm to 100mm it certainly rode better as an all rounder, so curious whether the Anthem X would do the same with the extra 20mm.
I also see that Fox is selling the 100mm with a bolt-thru option this year.
