The M9's ability to operate in 8.5, 9.0, and 9.5" travel settings is part of what makes it such an effective solution for taking on just about any DH course on the planet. The flip-chip hardware kit includes right and left side flip-chip mounting hardware.
Flip chips are sold individually. Offset chips are for the 8.5" or 9.5" travel settings, and center chips are for the 9" setting. The left-side chips are unthreaded, and the right-side chips are threaded.
