Cane Creek eeSilk suspension seatpost modernizes, lightens the Thudbuster

Cane Creek eeSilk takes their classic Thudbuster suspension seatpost design and gives it a solid diet and muted gloss-and-matte black finish, sending it straight into the modern gravel bike and endurance road market. The new design sheds more than 150g off the original, but retains the simple parallelogram and elastomer design.

For comparison, the standard Cane Creek Thudbuster seatpost comes in at 454g at its lightest, with 33mm of travel or more. This new eeSilk post comes in at a claimed 295g and has 20mm of travel. And it comes only in 27.2 diameters with a 350mm length. The body is forged aluminum, with machined alloy arms and hard anodized pins. The seatpost clamp uses titanium bolts to secure it, with a integrated thumbwheel on the front bolt. It’s compatible with both standard round rails and the oblong rails often found on carbon rail saddles.

It ships with three different elastomers to cover riders weighing from 100lb to 260lb. An extra soft (for riders under 100lb) and extra firm (for riders 260-320lb) are available separately. To swap them, just remove one of the pivot bolts, no need to remove your post or pull it off the bike. It even ships with a special tool to make the process easier.

Retail price is $289, available July 2018 through their website and independent bike shops.

So, lighter but more $, less travel, apparently less offset, and the minimum insertion looks bigger too. Pass. 🙁

“Looks bigger too”? I’d bet it’s approximately 54.4mm.

Junk. Less travel and no way to control sag without making the suspension stiffer. The old ones barely lasted 100-200 miles without wearing out. This looks to have the same weakness.

I doubt it is meant to be set with sag for with only 20mm of total travel. This is a comfort device, not a sophisticated suspension. They last a very long time if taken care of, which is far easier to care for than say a chain. Just wipe it off and a dab of oil on each pivot every now and then.

Ascarlarkinyar – what are you looking for in a “way to control sag without making the suspension stiffer”?? That’s basically what ‘adjusting sag’ is – making stiffer/softer. I seriously doubt (if using the proper elastomer(s) for your weight) your old one lasted 100-200mi. Unless you rode 100-200mi over 5+ years and stored your bike on the front porch, in the rain, etc.

Also, Dinger – kind words!

Yeah, what are you saying wore out? Elastomers? Pivots?

With the apparent disappearance of USE, there are apparently no decent suspension seatposts on the market today with more than a smidge of travel.

Tim – did you see / check out / try the existing Thudbuster LT and/or ST? These offer ‘more than a smidge of travel. Do you doubt they’re “decent”?

The USE looks well built but looks like it would change your effective saddle height when moving through its travel. Comfort/city/beginner bike riders don’t seem to mind. Do you not notice this?

Tim, dude, where have you been? Unless you only want a telescopic post, there have been a number of new suspension posts hitting the market in the last few years, including, but not limited to, the Shockstop from Redshift and the Bodyfloat from Cirrus:

I dig it… I’ve used a Thud ST on my gravel rig for a while but its heavy. I’m totally into this if it performs the same. The ST had a tad too much travel and was heavy. Sub 300gs aint too far off rigid post weights and I like having a little added cushion for the pushing.

Thudlife!

This looks excellent. Should sell a TON of them to the gravel set.

Between this and Rotor 1×13, my wallet’s starting to get real nervous. This weighs only a bit more than a Specialized CG-R and looks like it might be more sensitive.

why no full carbon option? take the LT and ST and build them out of carbon. if companies can make suspension linkages out of carbon fiber then these seat post could be too. heck, even if the post was carbon that would drop a ton of weight. If Cane Creek wont do it someone else should.

I bet a full carbon option would be pretty expensive! That’s a good suggestion though – I bet none of their engineers thought of that. Why don’t you like aluminum? Or are you just looking for an even lighter option?

Our Salsa Fargo’s came with the ST Thudbuster and after thousands of miles on two bikes, that seatpost is still working perfectly. The disadvantage of the the old Cane Creek design for the ST, was the valuable “real estate” along the seatpost the link system took up. That space on the seat post is needed for attaching seat bags, lights, fenders, cameras, etc. The new design appears to be better from the standpoint of leaving that valuable space on the seatpost alone.

I have a couple of rides on Eesilk and I’m utterly disappointed but it’s side play. The saddle is firmly set but it moves left and right.
