DK Inverted stem

[skki3330]

What year did they start making DK Inverted Stems?

[Dannywhac]

1" quill or 1 1/8"?

The 1" ones were real late 70's I think?

1 1/8" 'Jumping Stems' which can be flipped were 1998.

Inverted ones were early to  mid 80s, I remember seeing a timeline somewhere, will see if I can find it.

yeah that look smore like an 80s one ... the design stayed the same but got a bit chunkier early 90s ... around the time that they made the WAL ones

Looks like a mid 80's one as the early ones had squared off edges instead of smooth rounded off near the stem bolt.

Late 80's that one, introduced as part of the XL range plus it doesn't have the pin fixing the base to the quill which I think they dropped about 85/86.

I thought the curved edge top was late 80's early 90's and curved top and bottom was about 93.
