From what I understood in 'Racecar', the dogs on the Zeroshift are in pairs, only one of which is loaded at any time. The unloaded dog is disengaged from one gear and engaged in the next while there is no load on it - it is just gently slid from one position to the other with no side load as the load is carried by the other dog. Only once in the new position is the load switched over to the newly positioned dog, as the previously engaged dog is slid out while the torque from the engine is 'momentarily' removed. So it too has no side load at the time of being disengaged. Because of this I imagine that wear would be significantly less than on a dog box, where the dogs are crunched into position very crudely whilst under load (if you are not using the clutch). In fact, they used to be called 'crash' gearboxes, didn't they?
