The New BIRDY 3D forged stem has a function which not many people knows. The upper stem can rotate 180 to change the 21degree to 19.5, not sure if this info will help you but I wouldn't know this if I didn't visit Pacific museum.
Hello,
I have a new to me Birdy mk3 with sport stem
I am interested in experimenting with the 19.5 angle stem, I didn't really understand with part I need to rotate 180 and how, in order to accomplish it.
The only thing that I see that can rotate 180 is the post to what the handlebar is attached, rotating it means that you also need to rotate the handlebar.
It's like this?
I also wanted to confirm if is normal to have only one tire stopper for the front wheel to lock it when folded.
Thank you in advance
