He is getting together for a ride with some other guys and he had invited me to come along.He's even going to let me try out a few of his bikes since he will have all four of them with him.He rides his Giant mostly and said that the others mainly just sit there doing nothing.He has one that has full suspension and the others are Specialized and Trek hardtails.He's my size,6' 200-210 lbs and I think he said he rode a 19" bike,so we'll see how it feels.From some of the info I have read,it seems I should be on a 18",but I'm not sure how accurate that is.I also have an REI about 45 mins away that I'm going to.
