THE 28" trek tires and wheels have taken the pounding of the boney gravel of Eastern Maine and Maine roads in general [always bad]for years without normal complaint one broken spoke and 1 flat tire.The TIRES I run hard as a brick and on the gravel of the stud mill road I stand on the pedals all I can. In my good rideing yrs I went about 270lbs now 240. I would recomend my 7300 Trek 24spd. as a tough utility bike./Kenneth
