I expected the eeSilk+ to basically take the edge of of chatter but it is more effective that that. On my first ride I sought out some rugged, rocky terrain to test it out and I was impressed. I was able to descend rough terrain trail faster and more comfortably that before. I'm glad I bought it.

I'm quite pleased with this post. I put it on a steel touring bike where the road crack thumps were just starting to be rather annoying on long rides. This post does an excellent job of taking the edge off of them so the accumulated effect isn't so tiring. It does this while not exposing itself as flexible on every pedal stroke. It is subtle but effective, just what I wanted.

One note: I went for the firm elastomer in my weight range and found that to be too rigid. Once I stepped down, the magic kicked in. Annoying to have to buy parts to make the change, but the change itself is really easy. Consider selecting the lower of your options when looking at elastomers.
