It seems I'm getting more and more senior moments. Or maybe it's because I have different bikes that I have to change rim sizes on all of them. Let see, Africa Twin stock rims sizes are 17 and 21. One bike is still stock (what's the matter with me?) and the other is 18 and 21. GS stock sizes are 17 and 19. Mine are 18 and 21. I can see how I messed up on the front size of the Elefant. But I would have changed it to a 21. Yeah, that's it.
