essentially it just makes the compression ring and HIC shim all one piece. nothing revolutionary.
they fit "standard size bars" because they downsized the forktube. that interently makes it weaker.
Its cold forged which means the tube actually has a second hardening process after being produced which gives it a uniform wall thickness and increases strength significantly. Also the landing ring is still on the fork itself so there is no change there. Futhermore they will never be ran without the IHC shim and with the shim it has a wall thickness greater then almost every other fork out there.
Not weaker..
