hutch stem help!

Yes I think you have it Dave

Lets imagine the stem has three parts Top cap, middle section and then the shaft. If you were to take the underside of the middle section (where the shaft exits) and at 90 degrees to this horizontal, draw a vertical centre line (in the centre of the shaft) then you are saying that the bottom of the shaft is not on this centre line like the top is




If thats the case then the machining of the middle section is out. So as we all know the Deep H stems were macined to angle the stem down over the front.

 It may be that on this certain Friday at about 16:45 in a dusty American township that some fella or for that a "lady" did not line it up 100% and it actually slopes to the side.

Of course this is accentuated over the full width of the bar when one bar end is lower to the ground than the other.

So with that rational take a set of Hutch Pro bars that were made on the same day, same time by the same person and all should be OK because they are probably bent wrong.

I would be interested in how much difference it makes to the bar end heights.  :chin:

Ahh, no, thought we had it there for a second. Imagine the shaft was produced perfectly normally with no probs. But when it was pressed into the lower of the stem it was rotated about 15 degrees. Try to imagine the stem in the bike/fork and the handle bars being kicked out of alignment to the right....the stem is square to the body (as normal) just twisted slightly out of alignment......like you turned the handle bars to the right but the forks kept pointing straight. Lovely drawing by the way.

So you like you hutch's rad? you got any pics of them,i was looking a hutch stem a week or 2 ago but ended up going for a tuf neck :daumenhoch:,i wouldnt mind a black hutch f&f if i could get a cheapy  "wantit"

DY85262:
OK
Now I see.
Yes Dave you were right.



So everything aligned correctly when pressed in. The issue is the fact that the shaft is rotated aprox 15 degrees (See the plan view of the shaft). Hence when you look at the stem from behind and if we had see through headstocks and sterrer tubes we would see the apex of the wedge of to the right or left  by that rotated amount.

Is that right or is it a  "nono"

Of course this does not matter at all as the sterrer is round with no split its just a method of "wedging".

raddad:
Loving the art! Thanks for all the replies felas. I'm going to stick this stem in the for sale area then.
