You have not been around long enough to even understand back pain and thank your lucky stars. First, Take a look at a factory butt seat like Triton, it sells for $125. That seat is a SAS seat and there is a reason why it cost what it does. I just bought a new seat and power pole with base plate and it was $200 W/O shipping. Next do a little research on the back and how the muscles are tied together. Then understand what I call the little jelly donuts that sit between each vertebrae and what happens if one ruptures, herniates or is just bruised.119 bucks for a butt seat.my back would have 2 hurt pretty bad to pay that
