Rigid`s a good decision. I`m running Schwalbe Marathon Supreme 28 x 2in on a hybrid myself and haven`t tripped across anything they can`t handle yet. As a reference I also drive a mtb with 2.5in tires and a $1,200 130mm front end from DT Swiss and in the city I really can`t tell if the lockout is off or on. The tires are more than enough for city roads - even in pathetic state of repair.
