Tool designed,
for precise alignment front wheel with respect to the handlebar. Got the idea from some commercial tools available on the market.
The laser angle is adjustable to compensate different models of stem.
Before use check the laser alignment of the tool by putting it on it's side on a flat surface and check if the laser is pointing at the same height eg on a wall when the tool is flipped to the other side. You can adjust the height by rotating the laser and fixate it again.
