Seen lots of custom wheel combinations on the SE. Most commonly the 19/17". I'd like to run a 19" on the front for my road rides. It would cost less buying just one wheel and also quicker changing just the front wheel back and forth for various rides. Anyone know if a 19"f/18"r would upset or ruin the handling by dropping the front a whole inch, while maintaining the same rear height? I usually run a 50/50 rear tire for everything and a 21" knobby on the front. Would be nice only having to purchase one wheel and simply swap the front based upon what/where I'll be riding. Any thoughts?
