from my understanding... it says you have to swap all 3 components together... that means reversing the stem, headset and entire fork back to a normal one like ours...
and i don't think there is an upper cup being sold alone and the internal diameter of the lower cup should also correlate to the upper cup since it is practically the same girth that is going through the bottom opening of the head tube through the upper opening...
You are correct!
Been searching for the OD2 stem info but most are discussed in taiwan website/forums, here is it (from
Mobile01 again)
1. 有人去看過Giant做給OD2用的龍頭嗎?最短70mm,一個要訂價2000,這種價格再添一點點可以買到thomson了吧?
2 頭碗市面上還沒有1 1/4"的,想換都沒得換,萬一很倒楣的頭碗壞掉還不知道要去哪裡生頭碗
3. 總結:要換龍頭,那前叉頭碗也要一併換掉,除非你買Giant的龍頭
4. 要換前叉,那還是要連龍頭和頭碗一起換掉,不然1 1/4"的頭碗和現在的前叉都不合
5. 頭碗壞掉,一樣前叉龍頭要一起換掉,因為是面上買不到1 1/4"的頭碗Roughly it says:
1. Shortest Giant OD2 stem is 70mm, costs TWD2000, top up abit can get Thomson..
2. No 1 1/4" headset in market, if spoil will be difficult to find.
3. If changing stem, have to change headset as well, unless buy Giant stem.
4. If changing fork, have to change both stem and headset, because the 1 1/4" headset is not compatible with the fork.
5. If headset spoilt, have to change both fork and stem, cos no 1 1/4" headset in the market...
Sorry bad translation, hope you get what it means, or better still if you can read the original text
Guess most important now is as you said, check with the dealer/shop on the availability of other length OD2 stems
