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. ### ⭐⭐⭐⭐⭐ Worth the money. *by N***H on March 19, 2018* 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. ### ⭐⭐⭐⭐⭐ Nicely suprised, solid construction, I’d buy again *by F***F on February 9, 2019* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/71230179-carbon-seatpost-27-2-30-8-350mm-400mm-3k-carbon](https://www.desertcart.tn/products/71230179-carbon-seatpost-27-2-30-8-350mm-400mm-3k-carbon) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-25*
