Short of getting the crank dialed in to zero (no runout), there are only a few things you can do:
- Switch to Pro Taper bars...more flex
- Switch to big fat "Pro" grips. For less than $10 you won't believe the difference.
- Bar inserts. These are brass inserts that you stick in the end of each bar, and they ride on rubber orings.
- Loosen your grip on the bars...assuming you are running a Scotts dapener. Riding more relaxed without the death grip on the bars was the single best fix for vibration, as less vibration is transmitted when you don't hold on as tight.
- I think Paul swaps the rubber bar mounts for solid mounts, but I have never tried this change, so can't comment on it's impact on reducing vibration trasmitted to the eye balls through your arms. (after 75 miles on a bike with lots of vibration, my eyes go numb
)
Of course, you can always change your sprockets to 15/40 so you don't have to rev so high.
