Glad Origin8 makes this - I looked and looked for a zero offset 26.6 mm seat post for my old bike, and I didn't find much. Luckily, I found this. First, some questions and answers: How is 400 mm measured? From the bottom of the tube to the center of the seat rail clamps. How much did it weigh? 331.4 g Why was that last question in the past tense? Because I cut 7" of tube off the bottom end. It leaves me plenty of insertable length (4" is the minimum), and it brought the weight down to 236.9 g. Makes me wish I cut off another 1/2", and I could have said I reduced the weight by 100 g. What is the finish of the inserted tube like? It's got grooves or ridges, whatever you want to call them, like a tube turned on a lathe? How deep? How rough? If I run my fingernail down the tube, I can hear a zipping sound, but I can by no means catch my fingernail in the grooves. When the tube is wiped with a cloth. it feels smooth, and no fibers catch on the surface. How does the seat rail clamp work? It is a rocker pulled into a saddle, and tightening the front screw while loosening the rear brings the saddle's nose down. Are there ridges on the rocker and inside the saddle, or is it smooth and infinitely adjustable? The latter. What country is it made in? Taiwan. Why Origin8 wouldn't advertise this fact, given the excellent reputation of various Taiwan bike parts manufacturers, I don't know (I love Dia-Compe and higher-end Tektro stuff). Even more mystifying is asking the desertcart community what country and getting the answer, "I don't know." Really, I wasn't asking you personally. I was asking people who know. I am more than satisfied with the quality of this seat post. It is well built, and it looks good on the bike. It is very easy to install and to install a saddle on it. All the parts stay together, no nuts or bolts have to be removed, and the rocker portion cannot fall out. It's easy to adjust the pitch (up/down angle) of the saddle. A 5 mm Allen wrench does it all. Tube diameter is accurate. It slides into the frame and clamps securely. Review: Very nice seat post!!! - Very nice seat post, this is the 2nd one I've bought, different size from the last one i bought for another bike .

I will definitely buy another for my next build! ### ⭐⭐⭐⭐⭐ Origin8, nice quality at a reasonable price *by L***R on September 10, 2025* Origin8. Well-made and inexpensive. If you want fancier, or lighter, or name-brand, go for it. But if you want a quality part that does the job for an affordable price, I recommend Origin8. ## Frequently Bought Together - Origin8 Pro-Fit Alloy Seat Post - Park Tool PolyLube 1000 Bicycle Grease - Origin8 Pro Threaded Headset, 1" Steerer --- ## 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.com.eg/products/5170202-pro-fit-alloy-seat-post](https://www.desertcart.com.eg/products/5170202-pro-fit-alloy-seat-post) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-08-15*
