Carbon SeatPost 27.2 30.8 350mm 400mm 3K Carbon Fiber Bicycle Seatpost for Mountain, Road, MTB, MTN, BMX (Black)

Easy swap on my schwin loop folding bike. Very light weight.

The seat post worked great. I experienced some unexpected flex, but it softens the bumps. I’m 220 and 6’ 1” so I have the post extended a bit out of the frame, I got a 400 vs the 350 to compensate for that. It fit perfect in the 27.2 sleeve. I ride about 7 miles of fairly aggressive single track and hit the jump track with the kids, no issues. The 2 screw adjustment was simple and secured the seat properly. The weight may be a little less than my old aluminum post. Honestly I was a bit suprised buy the quality. Time will tell if it lasts, but happy with how it rode yesterday. I’ll follow up if it fails.

Needed a new seat post to replace my old one without breaking the bank. Wasn't really looking at carbon, but came across this product and thought I'd give it a try. Glad I did, it is much lighter than the alloy one it replaced and the fit and finish is on par with more expensive products. The 27.2 mm size fit the down tube without clearance issues and adjusting the angle with the two bolts was a breeze.

Great product at a low cost it's not going on a Colnago. Check the inside Diameter of your post on your bikes seat post tube before ordering and get the sizing correct. Use carbon fiber grease and torque gently. You can crush Carbon stuff easier than Alloy.

Pretty much useless to me. I am a professional mechanic, got this in a pinch because of the great price and fast shipping. 2 bolt design head is fine, hardware isn’t anything special, cheap looking but it’s a cheap post so that’s expected. Seat doesn’t provide much support for saddle rails. Big kicker is the post is quite out of spec in terms of diameter. Diameter varies between 26.6 to 27.0 on different parts of the post as measured with my digital caliper. It has a good amount of play and will not stay up no matter what amount of torque is applied. Frame is high quality as is the seat post clamp. I used high quality carbon anti slip compound as well. Issue is not the frame, many other 27.2 posts have worked in there. Can’t speak for other sizes but the 27.2 I received was completely useless.

I needed a new seatpost for my new saddle because the old post had saddle adjustment screws on top and bottom that worked fine with my old split saddle but not with the new solid saddle. I didn't want to spend a lot of money but I also didn't want something that weighed too much since the new Brooks C17 saddle was significantly heavier already. I found this by chance and thought I'd give it a shot. My 27.2 350mm post weighs 213.5g. My old post weighed in at 311.2g. The carbon post without hardware weighs 144.5g and the hardware weighs 68.6g. The post diameter is 27.1mm and I had no problems inserting it or tightening the collar. I used Finish Line Fiber Grip so the post doesn't twist and slip. The carbon material is quite thick compared to my other carbon posts but it's not much heavier. It feels very rugged and solid. The overall finish is quite nice. It looks beautiful. I would have preferred a UD matte finish but the glossy 3K weave matches the rest of my carbon bits such as the head spacer and handlebar accessory holder. There's a nice color transition from the aluminum hardware to the carbon post from all black to carbon weave. Overall, this is incredibly priced and is lighter than most high end aluminum posts. I'm really impressed.

Easy way to upgrade your post hight.

Looking for a new seat post to upgrade from my factory issued Bontrager, I came upon this one. It's very light, well made and easy to install. Make sure you get the specs of the size post you need before purchasing. It seems just a fraction thinner than 27.2 or perhaps the finish of the post makes it slip a little more inside the frame. I noticed tonight when I was riding, the saddle moved around a very slightly on me. I'm sure it's nothing that electrical tape can't fix. Very nice carbon fibre post for the money. Would recommend.
