As the bike started to wear in, I had slippage with the rear wheel slipping forward on the drive train side in the dropouts, which resulted in the wheel butting up against the frame and anger.
I finally took it into the shop, and they replaced the axle and the nuts which had been stripped from this process. On the ride home from the shop, it happened again. They "fixed" it a second time, and told me that there wasn't much more they could do for it. They pointed out that the riding style (lots of stop and go) leads to high torque and referenced some of the newer Internal Geared Hubs that have an axle with flat ends, like this one. The problem was, they said, is that they didn't know of anyone that sells such an axle that would "fit" the Torpedo. They were reluctant to grind down an axle for me, but said that if i could find one, it could be held in place with slotted washers like these below.
