The Fizik Cyrano is everything you could ever want from a seatpost: simple, light and easy to use. It's crafted from aluminum for a fantastic blend of low weight, stiffness and durability. And, it features an internally ovalized cross-section to save precious grams and boost power transfer, a long lower clamp to better support saddle rails and a short upper clamp to maximize adjust-ability. What's more, it's even compatible with both round and oval saddle rails. 27.2mm x 330mm
