The eeSilk Post comes in a 27.2 diameter and is 350mm in overall length. Interchangeable elastomers allow the post to accommodate riders ranging from 100 lbs (45kg) to 330 lbs (150 kg). I’m not sure. It’s worth measuring the inner dimensions of your seat-tube just to make sure (callipers are a good tool for that). One (precise) measurement is often better than a thousand expert opinions”– author’s expert opinion. 🙂

Seatposts by nature are simple beasts. Dropper posts notwithstanding, the clamp is the only mechanism. Most posts have adopted versions of the same system for years, with a variation in the number of bolts often the only difference. We were very impressed with the way that the Thudbuster allowed for a smooth and controlled cadence over rough terrain. With other seatposts on the same paths, the result had always been an over-geared hover over the saddle to try and mitigate the incessant impacts.There's plenty more options available - just make sure you opt for one in the correct diameter and with sufficient length for your riding position.

Suspension Seatposts Wrap Up

When engaged, the suspension linkage compresses a steel spring inside the post’s column that’s sandwiched in between two plastic spacers. All of these innards are compressed against a hollow plastic pipe that seats against a threaded preload screw at the bottom of the post. Redshift also includes a smaller, secondary internal spring to provide additional firmness, depending on your desired ride feel. The photo sequence above shows me sitting on it set up out of the box—main spring only, with preload somewhere in the middle—with its sag affected by only my weight (about 175lbs). Ritchey company used to be quite good, but I haven’t bought anything from them for a while – and they don’t seem to be making any 25.4 mm sized ones.
