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: I find this style of seat clamp is easier to adjust - I find this style of seat clamp is easier to adjust tilt and stays more secure then others. I would buy again! ## Features - Lightweight and durable AL-7050 aluminum construction ensures strength and longevity while reducing overall bike weight for enhanced performance on the road. - Innovative low-profile dual bolt micro-adjust clamp allows for precise fore-and-aft saddle positioning, improving rider comfort and optimal bike fit. - Bead Blast Black finish provides a sleek, modern style with superior corrosion resistance, making it ideal for both daily commuting and competitive cycling. - 350mm length with a 27.2mm diameter and zero offset design offers versatility for various bike frames and riding styles, from endurance rides to professional racing. - Engineered with stainless steel hardware and forged from a single piece of aluminum, this seatpost combines performance, engineering excellence, and affordability for serious cyclists. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NPV3SDG | | Best Sellers Rank | #91,789 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #63 in Bike Seat Posts | | Bike Type | Road Bike | | Brand | Zipp | | Brand Name | Zipp | | Color | Bead Blast Black | | Customer Reviews | 4.8 out of 5 stars 44 Reviews | | Included Components | Seatposts | | Item Dimensions W x H | 1.07"W x 13.78"H | | Item Weight | 0.5 Pounds | | Manufacturer | Zipp Speed Weaponry | | Manufacturer Part Number | 102303 | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 102303 | | Product Dimensions | 1.07"W x 13.78"H | | UPC | 710845862281 | | Unit Count | 1.0 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** Zipp - **Color:** Bead Blast Black - **Item Weight:** 8 ounces - **Material:** Aluminum - **Product Dimensions:** 1.07"W x 13.78"H ## Images ![Service Course Seatpost 27.2mm 350mm 0mm Offset Bead Blast Black | bike-seat-posts-and-parts - Image 1](https://m.media-amazon.com/images/I/41oYio+RZHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Chipped, but I can't be mad... *by S***T on October 2, 2025* This is quite a nice seatpost.
