your an idiot is why
its easy to figure out
its basically doing what brass knucks do
but instead of it being the giant ass clamp its a small shim which is pulled down by a starnut inserted into the forks and a cap on the top of the shim and a bolt is inserted and when its tightened it pulls the shim down to compress the headset to preload the bearings.
How its hidden? the shim goes over the forks but inside of an oversized set of bars
(inside diameter is bigger than normal)
instead of a giant clamp
understood?
Any fucking more simple and my mum would be making them.
