Hello all, I have what I hope is a simple question: under acceleration, is the rear end rotating towards the front of the bike, compressing the reaction rod, or is it rotating towards the rear, stretching the reaction rod? My semi-familiarity with suspension engineering tells me that since shaft-driven bikes want to raise the rear of the body under acceleration, the pinion is trying to "climb" the ring gear, forcing the swing arm down while rotating the rear end housing forward, which would put the reaction rod into compression. If that is indeed the case, would the stretching (tensile) forces be marginal under braking as I suspect? I would greatly appreciate any and all input. Thanks. P.S. I'm sure most of you know that the drive shaft turns CCW, but I just want to add that.
