The rear derailer:
For the front derailer you have to install so the height is only a few mm above the teeth. To take the guess work out of this Shimano put that little red sticker that you can in the picture. It has little wavy outlines for the teeth and you just adjust the height until they are aligned.
Front and Rear brakes.
And the shifters:
This phase of the build was very easy it was just bolting things into place and at the correct torque.
The last few steps required a little more thought and tweaking.
