Hello I am looking at putting a 21" up front and an 18" rfear wheel on a 2002 FLSTC. What if anything do I need to change out (fenders,brakes etc...). I am looking at using some 80 spoke wheels. I posted this the general wheel and brake forum and got know response so hopfully it will work here.

 

Tons of bikes running that combo. Use the search and you'll find a whole bunch of info. Only issue should be front fender clearence.
