Folding Stem Upgrade - Version 1

Here is the stock stem.

It has a folded collar. After repeated flexing, the thin metal gives way and bends.
The locking mechanism is also crappy.




Version 1 Upgrade

Here is the first mod by cutting away the bottom pipe which is used to secure the stem to the fork by friction angled nut. Two flanges are brazed onto the existing telescopic pipe and stainless steel cap nut is used for securing them together.

The disadvantage is having to keep an allen key around to remove the cap screws in order to separate the stem when folded.
