LIGHTWEIGHT 25.4mm BICYCLE ALLOY SEATPOST SADDLE STEM 300mm LONG

Product Information

Does the frame have some shims that reduce the seat-tube’s inner diameter, allowing such a narrow seatpost to be held in place? Most seatposts are a lot wider than 15.75 mm. Machining the sidewalls down would weaken them tremendously in my opinion.

Continuing their 20-year suspension seatpost legacy, Cane Creek recently announced the all-new, fourth generation Thudbuster ST (Short Travel). Designed with touring, commutes, and e-bike trips in mind, it features 50mm of travel—up from 33mm on the original Thudbuster ST—to smooth out bumps and bounces on multi-surface rides. Building on the original Thudbuster’s parallel linkage, it also got a redesign for a higher rider weight limit (now up to 330 pounds), increased durability, and more travel. If you find any other mistakes, feel free to note them. I try to keep this as correct, and up-to-date as possible. One thing I really liked about the Kinekt is the saddle rail clamp. It has two simple screws to tighten and adjust the saddle. There’s a spring that keeps tension to separate the lower and upper plate. This self-fixes the nuts into place so you don’t have to hold them while loosening or tightening the plate into place. A nice touch. while going a bit too wide would call for some more grinding – but it’s probably a safer way to go (“measure three times, cut once” is a local saying).If you use a carbon seatpost, make sure to fit it using a thin layer of carbon paste as this stops it slipping. Pay attention to the quoted torque at which you should tighten the bolt - overdoing it can cause it to snap. If you don't own a torque wrench already, here you can find our recommendations for the best torque wrenches for bikes.

But, a narrower pipe could probably be sourced, or even a steel rod – then it’s up to finding a turner to process it into the appropriate diameter size.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). Though some brands like to play exception to the rule, the majority of bikes are designed to fit a seatpost of either 31.6mm or 27.2mm. One (precise) measurement is often better than a thousand expert opinions”– author’s expert opinion. 🙂

The results were as I might have expected. All the posts performed really well. All of them helped reduce chatter. The carbon posts had a little more ‘give’ in them. But ultimately it would be tough to say that any of them outperformed the other by any serious margin. Value 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. All seatposts clamp to the saddle in their own unique way, and have different methods of allowing the saddle to point slightly down, slightly up or remain flat.

Suspension Seatposts Wrap Up

The Cirrus KINEKT 2.1 is an aluminum suspension seatpost that’s designed to isolate your body from surface vibrations and impacts to improve comfort and control. Each post comes with two extra springs so you can mix and match, creating a custom experience. The KINEKT post springs are available in five color-coded tensions for riders ranging from 50-320 pounds. If you don’t have calipers, you’re hard-pressed to get the diameter. An adjustable wrench can be used as calipers, then measure the gap on the wrench. However, it’s almost impossible to distinguish 0.2 mm increments with a tape measure.
