Hello,

I am new to mountain biking and am looking for my first bike. Found a great deal on a Trek 4500 that is an 18" frame with a 30.5" standover. I'm 6'0". Will this bike fit me?

I know ideally I would want a 19" or 20" frame, but will the extra inch make that big of a difference if I'm just a casual biker?

Thanks for any help!
Bryan
