Our Cyclecomputer database is your starting point when looking for information on cyclecomputers. It links to owner's manuals for most cyclecomputers. Sometimes we had to work without a manual, or have additional information. It's on this page for some Vetta computers.
Look for similarities in appearance and function when trying instructions for a computer not on our list. Many bicycle computers are rebranded. Please let us know of rebranded models which you have identified.
Old versions of manufacturers' Web sites preserved on the Internet Archive may list older models. A Web search on the make and model, plus "manual" or "instructions" sometimes turns up information posted by an owner. If you have information on a model not covered here, please send it in.
