Cyrano R1 Seat Post The Cyrano R1 is the carbon seat post from fi′zi:k. Made from uni-directional carbon, this is both strong and lightweight with a sophisticated high-gloss finish. It is available in 3 diameters (27.2, 30.9 and 31.6mm) and 3 lengths (270mm, 330mm and 400mm) and is designed to perfectly complement fi′zi:k Cyrano Handlebars and Stems. These products are being ridden at UCI World Tour level by AG2R Pro Cycling Team. -This seat post clamp is easily adjusted and quick to install a saddle into.-The saddle clamp is designed specifically to be saddle rail-friendly, ensuring an even dispersal of the load once a saddle is clamped in place.-There is lots of fore-aft adjustment along the saddle rail as the top part of the clamp is shorter than the base.-The saddle clamp has a flat top with no screws protruding. This means there is no danger of reducing saddle comfort derived from a dynamic saddle base that might otherwise be restricted from moving.-The post can be used back to front, releasing the adjuster wheel all the way. This allows the rider to be closer to their bars in triathlon or time trials.-All seat post clamp parts are heat-treated for 3 times the industry standard, making them particularly durable and corrosion-resistant.
