would 28 up front and a 23 on the back be too much of a size difference? Would I run into any problems?
Im new to this so i don't really know what I'm talking about.. But, wouldn't it seem wierd to run bigger tires up front?

I'm really hoping for better handling if I ever run into a lightly graveled road or somethmg.. Would the thicker tire up front help? Or should I put it in the back?

If it helps, I have a fuji track frame.
