WARNING: The drive side and non-drive side Horst flip chips must both be
aligned in the same high or low position. Improperly installed Horst flip chips
can damage the frame and can also cause you to lose control and fall.
All models are assembled with the flip chip in the high position. Switching to
the low position lowers the bottom bracket height by approximately 7 mm and
slackens the headtube angle by approximately 0.5 degrees.
