I bought this product there is already a few months, trusting the fact that I already had this kind of product. This model is far from the one I had bought before: - The wheel is very narrow and too small diameter (no stops) - The steel frame is very heavy - The bag is very poorly suited to the chassis; it tears very quickly. The model that I used before (and I use yet) has a frame of aluminum tubes, a slightly larger inflatable wheel diameter, but much more comfortable and the bag of greater capacity, although somewhat porous (for wear) do not tear after 10 years (approximately) of service.
