eeSILK Post

Ride further and explore new terrain with the eeSilk seatpost from Cane Creek. The seatpost uses an elastomer shock absorber providing 20mm of vertical compliance to help smooth out rough roads and choppy gravel terrain. Cane Creek claims the 20mm of travel reduces fatigue and gives you more control when things get bumpy, allowing you to do longer rides and take routes you'd normally shy away from. Using lightweight aluminum construction and titanium bolts, the eeSilk comes in at a reasonable 295 grams. This weight is comparable to most rigid seatposts, so there's little to no weight penalty to try out this extra cushion for yourself.

Cane Creek uses a parallelogram design that keeps your seat angle consistent as the seat compresses. They include three elastomer springs in the box to accommodate different rider weights, with a max rider weight of 330 lb.

Not too good

  • Familiarity: I've used it several times

When I first got this post I was very excited and admired its construction. However, I quickly noticed the inside bore of the post was covered in abrasive media that I didn’t really want falling down into my bottom bracket overtime. This was my first disappointment but would not be my last. (For nearly $300, it should be nearly pristine inside and out especially as this is advertised as Di2 battery compatible.)

I cleaned it out and move forward thinking that all was going to be great. However that was not to be the case.

At first, the mechanism was very tight and had no lateral or front to back play. I really enjoyed how smooth it made the ride. Bumps and rough spots just disappeared until you hit something big enough to throw you out the seat. I never really noticed it working but I did notice how smooth the normally rough roads felt.

Within a few days and less than 100 miles, it began to develop lateral play and also front to back play in the mechanism. The seat moves about a quarter of an inch in any direction under load. (So think about your saddle moving around in a half inch circle at the top of your seatpost and how that would feel.) Actually, I can wiggle it that much by hand.

In summary, this is a beautiful piece of machined artwork and engineering but is not a very good seat post due to the amount of play in the mechanism. It does work very effectively at smoothing out the bumps but is also effective at leaving your butt sore from a wiggly saddle.

I am returning it. I will end up with a credit at CC but will not get my money back exactly so I have basically bought myself a big gift certificate that is kind of useless to me. In the meantime I have to go buy another post to use now because otherwise I have to go through an exchange process and I don’t have the luxury of a second bicycle that allows me to have a bike that I can’t ride for 10 days or so during the prime season. So in the end I will buy two seat posts in order to end up with one seatpost and a store credit I have no use for.

Unanswered Question

Is the 350mm the total height or is it measured from the base of the hinge?
