The Syncros FL1.5 Aluminum offset seatpost borrows from the clasic Ritchey 2-bolt design with 25mm of offset. The post's head and cradle is a extra wide and 40mm long for added support. The seatpost clamp is forged 7075 alloy. The clamp is wide to fit the cradle and has a low profile clamp that reduces stress on the rails and won't bottom out on your saddle. Two-bolt design for easy to adjust and holds the saddle to the post with vise-like grip. Cosmetics are classic black on black Syncros and will match virtually ant frameset. Diameter is the becoming-industry-standard 31.6mm or 27.2mm and the longish 400mm length fits just about any frame, large or small.
