THIS is an interesting piece of tech, and i should immediately caveat that it's made for the downhilling/MTB set. downhill bikes commonly have an oversized 1.5" headtube (news to me, not being a mountain biker), into which one would install this headset, but then run a 1-1/8" fork. by doing so, the tech of the headset allows you to change your head angle by up to 1.5 degrees positive or negative from 0, where 0 is the actual angle of the headtube.

yes, you can accomplish the same thing by running forks with different rakes, but that requires a whole bunch of forks and this doesn't.

VERY fucking cool if you're a techie. which i am.

SICK.
