If you do not know the model and year of your bicycle, you will need to find it manually via the photos in the online archive. We will not be able to tell you this information with only the serial number. Note: A serial number does not indicate the size, model, or year of a bicycle.


Locate the row in the geometry chart labeled "head tube length" and scan across the row until you find the measurement that matches the measurement that you took from your bicycle's head tube.This will show you the geometry chart for your specific model and year in accordance with all of the sizes the bicycle came in. Once you've located your specific model and year in the online archive, click on the "Geometry" tab located under the photo of your bicycle.The archive section can be found by hovering your mouse cursor over the red Specialized banner in the upper left hand corner of any page on the website, then clicking on "Bikes" then clicking on "Archive." The geometry chart for your specific model and year (as well as other valuable information about your specific bicycle model) can be found in the archive section of the Specialized website. A geometry chart is a chart that lists all of the important measurements of your bicycle's frame in relation to each size the bicycle was made in. Once you have the length of your bicycle's head tube in millimeters, you can then compare that length to the geometry chart for your corresponding year and model of bicycle.You will need to measure this length in millimeters. It is the forward most part or "tube" of the frame and it is arranged in a slight angle off of vertical. The head tube is the part of the frame that the front fork inserts into. Measure the length of your bicycle's head tube.If a sticker indicating the size does not exist, then follow these simple steps: First, look over your frame to see if there are any stickers indicating its size (for example: 17, 19, M, L, 56, 58, etc.).
