I noticed that the registry was never updated to reflect the fact that my #353 is in Indiana, not Australia.

That was my alternate theory. You're saying that the ring gear is trying to "climb" the pinion? That seems like the tail wagging the dog. Keep in mind that the driveshaft is turning CCW (as seen from the rear) with the ring gear on the left of the pinion, which would seem - to me, at least - to impart a "downward" (forward-rotating) force. Any empirical data, or is that also a thought experiment? Passing up an easy joke, I really have no concern about what the reaction rod does under braking, as the forces involved are relatively low, so no sleep lost there. What is keeping me awake at night is not knowing what happens to the bevel box under acceleration, which was my fundamental question. Also, I wouldn't be concerned with any of this if I was using a factory reaction rod.

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.

Silicone, I believe...not sand - I mean silicon.

CORRECTION: I'm looking at #353 in my Hobart, IN garage, so I don't know how it could be in Australia. It was initially misidentified as "#232", I believe, from Janesville, WI. You would think an accountant would be better with numbers...
