Non-reacting suspension to breaking
Form the first post:
- It is possible, although not necessarily desirable, to have a suspension setup which does not have a squatting or extending tendency under brakes (at a given instant or instances). This, I believe, should be kept separate in terminology, from suspension extension due to weight shift. It is fairly easy to understand that if the brake torque/axle reaction force doesn’t exhibit a compressive or extensive force/moment on the suspension AT ALL, then under any braking the suspension will extend due to weight shifting forwards. For this reason, it may be useful to have some amount of pro-squat (tendency to compress). I know of no situations where it is helpful to have anti-squat (a net extension force, in other words actual “brake jack”) under brakes, as this only exaggerates the forwards weight transfer.
Question:
Wouldn't it be better to consider a system where the pro-squat fully counteract weight shift as a 100% non-reacting suspension to braking? I think this is what anti-squat calculation is about (use in bike suspension marketing for the DW-Link)
This system will not, when the rear brake is applied, create any add in vertical forces to the rider thus it will not create any vertical acceleration on him.
Wouldn't this system be the best compromise for having good bracking caracteristics?
