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

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.

Well worth the money. I didn't buy it for weight, as it really isn't significantly lighter than the alloy one it replaced, but it seems to smooth out the road a little as carbon posts are supposed to. I've only put about 50 miles on it so far so I can't speak to the durability but I'm 6'1" and I weigh 230 and it supports me just fine so far.

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.

This is not 27.2 mm... Though I do not have a micrometer, I tried three different bikes and this came up too small in diameter!!! I ended up using 1mm Klapton tape for a proper fit at the clamp. The side affect of this is the bottom of the seat post will smack within the seat post wall under flexing of your Frame!!! Now you have to take it back out and add Klapton to the bottom of the seat post.Not ideal for a custom build XC - MTB Bike.

great fit no issues at all will buy again .The clamp is a little fidgety but easy enough to figure out . Good quality , no flex I can tell with a test ride of 53 miles on my gravel bike with light offroading. Do be careful about seatpost clamp with any carbon post as too much will crack it internally and carbon will shatter in shards and not very fun

Been using it hard for about a month. The thing I like is it has a little spring to it. Smooths our some of the harsher bumps while seated.

I had a Bontrager seatpost that came stock on my entry level carbon fiber road bike. The former was a press fit bonded integration of many pieces waiting to disintegrate under my heavy load. This new post is a monolithic post with minimal attach parts - looks much sleeker than what I had and matches the bike architecture in terms of color and finish. This was a really nice value upgrade. Get you one !!!

As an amateur cyclist, I can say that this product is pretty good for the price. There's plenty of material in the seatpost, which doesn't make it very light, but it definitely dampens road buzz.
