HI,
I find with mountian bike I run 10 to 15 pounds lighter on the front wheel than the rear, this really seems to dampen the jarring effects, and my hands appreciate that.
I have a cheep soft tail but it really makes a difference when I ride on the road, or trail and hit a bump, or a dip, when I ride the steel frame roadie it really take a toll on my arss and back, hey it is a different angle of attack. but it glides better and faster, geeze....
Just moving your seat alittle back or up or down can change everthing.
