There's more to handlebar fit than the width of your shoulders. Fizik has designed a series of drop handlebars corresponding to their "Spine Concept," developed originally for their saddle shapes. Riders with varying amounts of spine flexibility will have different riding styles and prefer differently-shaped handlebars. Fizik aims to take the guesswork out of finding the right handlebar with the Cyrano series.
The Fizik Cyrano R1 Handlebar Made for Chameleon is intended for riders with a moderate degree of spinal flexibility. These riders can reach further than less flexible riders, but prefer to ride not quite as low on the drops as more flexible riders. This handlebar features a longer reach (85mm) paired with a shallow, ergonomic drop (135mm). Made of unidirectional carbon, the 420mm size weighs in at 205 grams.
