It came with a small chip on the clamp, making me think it was a returned item, but it's such a nice seatpost I can't even be mad about it. It has a seemingly generic tilt adjustment mechanism but it works incredibly well. Micro adjustments are a piece of cake. And it's quite sturdy, as well. I definitely recommend! (And the chip isn't so bad that a black Shapie marker can't take care of it) Review: My old saddle needed a zero-setback seatpost; when I changed to a saddle that needed a setback seatpost, I ordered this. LBS had junk. This is solid, easy to adjust, and holds the saddle firmly in place. Highly recommended 27.2 seatpost. ## Features - Lightweight, durable 27.2mm aluminum seatpost crafted from 3D forged AL-7050 for optimal strength and reliability during intense rides. - Innovative low-profile dual bolt micro-adjust clamp design allows for precise, secure saddle positioning with greater for-aft range of adjustment. - Bead Blast Black finish provides a sleek, modern aesthetic while offering excellent corrosion resistance for long-lasting performance. - Designed for versatile use, with a 350mm length, 20mm offset, and minimum insertion of 90mm, suitable for road, mountain, and hybrid bikes. - Stainless steel hardware and precise engineering ensure smooth adjustments and maximum security, delivering professional-grade quality at an affordable price. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NPXKJVZ | | Batteries Included? | No | | Best Sellers Rank | #60,711 in Sporting Goods ( See Top 100 in Sporting Goods ) #36 in Bike Seat Posts | | Bike Type | Road Bike | | Color | Bead Blast Black | | Customer Reviews | 4.8 4.8 out of 5 stars (122) | | Date First Available | 3 December 2020 | | Department | Adults | | Features | 2-bolt adjustability | | Global Trade Identification Number | 00710845862267 | | Height | 6 centimeters | | Included Components | Seatposts | | Item model number | 102299 | | Length | 44 centimeters | | Manufacturer | Zipp | | Material Type | Aluminum | | Number of Items | 1 | | Product Dimensions | 41.66 x 4.57 x 15.24 cm; 312.98 g | | Size | 27.2mm | | Style | Seatposts | | UPC | 710845862267 | | Weight | 0.3 Kilograms | | Width | 15 centimeters | ## Product Details - **Brand:** Zipp - **Colour:** Bead Blast Black - **Item weight:** 313 g - **Material:** Aluminum - **Product dimensions:** 27W x 350H millimeters ## Images ![Zipp Service Course B2 Seatpost - Image 1](https://m.media-amazon.com/images/I/41RIOi083aL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***T on 2 October 2025* This is quite a nice seatpost.
