那不是墊圈，而是 headset。圓形的才是墊圈，叫 spacer。差別是：一個是選用，一個是必用。
如果有裝過前叉，讀過說明書，拆卸過龍頭，應該會注意到：廠商 spacer 的安全長度或 spacer 安全長度加上「錐形墊圈」的長度約略等於「龍頭鎖在前叉那個部位」的長度（約 4-5 cm，因龍頭而異）。理由可能是因為龍頭下緣是受力最大處。所以我想，沿前叉方向，從龍頭最上緣（並非最頂處）至頭管上緣處總長若是大於兩倍「龍頭鎖在前叉那個部位」的長度，便可以稱作長頸鹿。

TREK的Bike Manuals 對於CARBON前叉的規定比較特別

BE SURE TO USE A CORRECT HEADSET SPACER CONFIGURATION
Always place at least one 5mm spacer below the stem. This spacer
rests on top of the bearing cover, which also must be at least 5mm in
height. Alternately, do not place a spacer group that exceeds 40mm
in height collectively underneath the stem. With a carbon steer tube,
always place at least one 5mm spacer above the stem and below the
top cap.
龍頭上下都要墊5mm的墊圈.....
