i am 5'10'' and weight 270 ,i have a trek 7200 that i been riding for a year now .we did a 25 mile ride today and one thing i noticed was that the other riders with the 100% road biked took off from a stop and with in a few strokes they where almost out of site.. i under stand that they are in shape and been riding sometime but there was some guys there that where bid as me and they had the same "pick up and go" could it be the bike? or will my bike do the same thing there bike do but i need more time on it..?
