Extend Your Ride, With More Compliance

These posts make great enhancements to gravel or mixed surface bikes by reducing the chatter transmitted from the surface to the rider and can be tuned to rider weight through a simple elastomer change.

  • Bolt-on compliance: Up to 35mm of travel to add comfort and compliance on gravel and mixed-surface rides without adding unnecessary weight to the bike.
  • Parallel-linkage design: Parallel linkage technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of the bicycle, the rear wheel pushes up and forward into the rider.
  • Easy elastomer change: The eeSilk+ seatpost can be tuned for different rider weights and riding styles by selecting the elastomer that best fits rider needs and preferences.

The eeSilk+ seatpost is shipped with a Medium elastomer installed. Extra Soft, Soft, Firm and Extra Firm elastomers are sold separately.

<110lb (<50kg) = #1 Elastomer*
100-160lb (45-73kg) = #3 Elastomer*
150-210lb (68-95kg) = #5 Elastomer
200-250lb (90-113kg) = #7 Elastomer*
200-250lb (90-113kg) = #9 Elastomer*

Q & A

Is the maximum extension for the carbon and aluminum version the same? The posts differ 25mm in length, but there is only one maximum extension shown. Tim asked on February 9, 2024

Hello, minimum insertion is 100mm for our eeSilk+ aluminum and carbon seat posts. Maximum extension for our eeSilk+ Alloy is 287mm and 262mm for our carbon.

Is there ‘sag’ when simply sitting on the bike or when riding smooth pavement? Or does your EEsilk+ design only cushions when one is riding over a rough surface? Brett Davis asked on February 1, 2024

Hello, there will be a bit of "sag" while sitting on the seat post, this is due to the riders weight and why we offer multiple elastomers firmness options.

I asked the wrong question the other day. I meant yo ask about the bottom of the seatpost. In my application, I will be close to the minimum possible extension (maximum insertion). On my Giant Revolt Advanced, the seat tube narrows to allow larger tire clearance. I am not sure if I can get the seat low enough. Also, I will be using a 27.2mm seat post with the adapter. Unless there is some spring or other active mechanism at the bottom of the seatpost, it seems that it should work just fine with 4 or more inches extending below the adapter. I am looking at the aluminum version which I would expect to have a hollow tube at the bottom of the seatpost. If it is a hollow tube, I should be able to cut it. The only issue would be that the “minimum insertion” mark would not be in the right place and the seatpost would have a shorter maximum extension. Brad asked on November 21, 2023

It is fine to cut the seatpost slightly for it to fit in your frame. There is no apparatus or moving parts housed within the post. Just be sure that you have ample seatpost extending past the adapter.

Can I cut the aluminum stem if it is too long ? Brad asked on November 13, 2023

You cannot cut or alter the stem itself in any way. This would void the warranty and also render it terribly unsafe to ride.

It looks like the alloy version has a knob for the front seat clamp bolt and the carbon requires a wrench. I assume that this is because the bolt is not accessible from below. The alloy seems to require one tool for fore/aft and tilt adjustments and the carbon requires two. Is this correct? Michael Newman asked on October 28, 2023

The eeSilk+ Carbon uses a wheel, or 4mm hex to adjust the front bolt and a 4mm hex for the rear.

The eeSilk+ Alloy uses 10mm wrench on the front bolt and a 4mm hex on the rear bolt.

I think the stock elastomer (Medium #5 BAE0323) is a little too stiff for me (215lb). I purchased the #3 Soft BAE0322, and it feels better. Great machining and quality.

The eeSilk+ seatpost works great on my Giant Revolt Advanced bike. It really smooths out the sharp edged bumps on our rough and cracked paved roads. It foes the job without calling attention to itself in any negative way.

My bike came with a carbon seatpost. With my height, there was not much exposed seatpost. The eeSilk+ is much more comfortable and allows me to contiue pedaling across bumps that I previously would have chosen to lift off the seat.
