Hypothetically will i die in a ball of fire if I use an angle headset that's designed for a headtube 15mm shorter than mine?
I'm guessing it'll rub/bind/wear out the bearings prematurely? Or will it be awesome?
Thanks

no, if its designed for a shorter HT then you'll get less of a change that's all
I'd disagree with the above and say that simple geometry says you'll be creating pressure spots on the bearing races and wearing out bearings faster. How much, I couldn't tell you. It's the same as having an incorrectly faced head tube.
Shorter the head tube, the more of an effect it'll have.
I'm with submarined on this because although it is true that
you'll get less of a change
the cups have been machined for the intended angle adjustment so the steerer will no longer be at 90 degrees to the bearings which isn't ideal. What I don't know is how bad the result will be.
I spoke to works about the cups I have and they said there is no issue other than a change in the angle you'd get. For me it's the ther way round so going on to a shorter HT.
Well that ^ has cheered me up, I have one in a 120 headtube frame that I would have liked to reuse in my new 105 headtube frame but was concerned I'd be pushing it a bit.
Happy days all around.
If you are going from a longer to a shorter then you'll get more of a change
I'm going from a short headtube to a long but guessing we're talking small percentage change on the expected angle either way.
Saying that if anyone had a longer headtube EC34 angle set then I'd be keen to relieve you of it!
