They are heavy and the weight is way up high on the bike, Very Bad..
They are great for mellow trail riding but are Un-damped so the 2 to 3 Inch travel Is like a fat bike tire In that aspect Except,,,,,,,
The fat bike tire is controlled by the rider bending his legs, making His/her body the damped shock absorber..
The seat will only compress and rebound Instantly at the worst time and the worst time Is anytime your rear end Is in the saddle....
On real trail riding we need to be OFF the saddle and ON our feet to help the bike absorb things..
You try and make the Thud buster a substitute for controlled rear swing arm suspension with managed rebound and compression on any real single track you will know pain,,, Intimately !
That thing is great for fire roads and nasty pavement cracks but does not belong on a Trail bike...
