I suppose we'll find out in the Fullness of Time, but it might still be an Awfully Good Idea to occasionally pull the adapter and put some new anti-seize on the threads to prevent galling to the hub threads.
At present, it looks a tremendously convenient upgrade for longer tours, and I am hoping the replacement adapter will be available separately at a reasonable price, as are the new-style "wave" shifter covers. Slotted cogs should be less expensive, as they will no longer require the four-start threading.
Happy days.
Sharp eyes, Pete; thanks!
Best,
Dan.
