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.
