Springs alone when coasting prevent squat unless there is a rolling surface (road or trail) induced compression of the CM when not pedaling or braking. It's amazing to me that no one could point this definition of squat clearly in all these years of discussion I was involved in before. However, due to the practice of putting the seat quite rearward of wheel-base center, if the rear suspension compressed 1 inch and the front extended the same, then the CM would wallow rearward and compress (squat) significantly. (Thanks to Strong-Like-Bull for the graphic.)įor example if the CM is half way between the wheels there is no squat when the rear suspension compresses 1 inch it the front suspension extends 1 inch and the CM remains at the same height. The attached picture below describes how the anti-squat line is determined. Squat is when the CM compresses overall when the front suspension doesn’t extend enough to compensate for the rear suspension’s compression. I guess this action is technically called "wallow". Antisquad line full#I've always considered that when a full suspension frame pitch rotated rearward from a compressing rear suspension, whether or not the front end extended, this was “squat”. I guess I may have been using the term "squat" incorrectly.
