Denis sent these photos of a pair of unusual Cinelli bikes that are part of a collection in Taiwan. One has a curved strengthening section between the top tube and down tube and an interesting bottom bracket configuration, the other frame has semi-curved seat stays.
If anyone has additional information about these particular frames please write in.
I will be posting more photographs from Denis in the future.
I invite you to contribute by sending in photographs of your Cinelli bike, illustrations, personal stories, and articles about Cinelli bikes and components.
