I have been thinking about upgrading to a 21" for a while now but have been hesitant because the only person I asked (at a harley shop) told me that I would need a custom rim made to accomodate the # of spokes. I honestly have never counted and nor do I care If there is a ready made rim that I can just lace up. Where have you all purchased yours? Oh and about the front fender- I took mine off and love it. As for the rain... I just check weather.com before I ride because my baby wont see a drop of rain If I can help it!
