LBS had junk. This is solid, easy to adjust, and holds the saddle firmly in place. Highly recommended 27.2 seatpost. ### ⭐⭐⭐⭐⭐ good seatpost. *by on Reviewed in the United States June 27, 2026* no brainer install. perfect. ### ⭐⭐⭐⭐ Excellent adjustability *by on Reviewed in the United States April 29, 2022* The seat post allows you to dial in your seat angle with fine granularity.If you're an older guy trying to sit on a young guy seat, every .1° matters. :)The post weighs a little more than I expected, but it isn't their high end. It is exactly like the way you would adjust a Thomson seat post. I needed a setback as that's how my frame is designed. I don't like the way Thomson does theirs with the bent look. This post is only same level as mid level Easton, or FSA.I have a Zipp drop bar too.. I like their stuff for road bikes. ## Frequently Bought Together - Zipp Service Course B2 Seatpost Black/20mm Setback, 27.2x350mm - Finish Line Fiber Grip Carbon Fiber Bicycle Assembly Gel, 1.75-Ounce Tube - Park Tool PolyLube 1000 Bicycle Grease --- ## 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.is/products/274878903-service-course-b2-seatpost-black-20mm-setback-27-2x350mm](https://www.desertcart.is/products/274878903-service-course-b2-seatpost-black-20mm-setback-27-2x350mm) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-16*
