I purchased a Mongoose Beast specifically to use the 4 inch wide rims. But I had to change the rear hub so that it would fit my frame. I swapped in a Sram Automatix hub. The two flanges are much closer to gather that the original hub. When I took these two pieces to my lbs to have a new wheel built, the mechanic did not want to build it. He said it was a bad idea to pair up that specific hub with a 4 inch wide rim because the spokes would be too close to vertical and that the wheel might collapse when I made a turn. The problem is I can't use a wider hub since my frame won't allow it.
Anyhow I was persistent so I just decided to learn how to build a wheel myself. So I built it and trued it to the best of my ability. It's 36 spoke 3-cross. I test drove it and everything seemed fine. as you can tell this bike iw simply a cruiser, not performance oriented at all. I am not taking any jumps on it and will probably be under 8 MPH all day long. Do you think it is safe though?
PS. I also have 2.35 inch wide tires stretched out onto the 4 inch wide rims if that makes any difference.
