This stem was originally white. I went through a phase where I liked the look of raw aluminum on my bikes, so I stripped the finish. I didn't finish the job so you can tell it was originally white. You could powered coat it white again or any other color for that matter. Hollow stem bolt/quill style. I tried to provide as a many pictures as possible to accurately present the condition. Do not hesitate to write with any questions.
