I'm thinking my risers might be amplifying the vibrations? Would putting a small piece of rubber there (like a cutout from a bicycle innertube) work? I figure a thin piece of rubber under the risers, and perhaps a thin piece above, then tightening to hell might reduce the vibrations. I've also been reading on people filling their bars with insulating foam... Most comments seem positive, but a few are negative. Has anyone tried this yet? I'm not too worried about adding weight. I even read about one guy who put beads of silicone on a piece of paper and once it was dried out, wrapped them all together and stuffed them down either side of the bars.
I know I can't have it all. My current setup works great at higher speeds. However, my hands do get tired quickly in bumpy slower speed stuff. Especially the small rocky stuff. Suspension doesn't absorb it as well and the ensuing vibrations reverberate all the way through the ends of the bars.
This is my current setup:



Here's a simple example of what can be extremely tiring... It's dried mud (but which is as hard as a rock) in a small winding track, which forces me to go slow. Tiny clumps, but they're hard and at low speed the vibrations are starting to make riding tedious...
