What's new at sheldonbrown.com
Sheldonbrown.com has compiled links to more cyclecomputer and bicycle GPS manuals, old and new, than you will find anywhere else on the Internet. We have once again added information on new models and re-linked when a brand has discontinued support, left the cyclecomputer business (Blackburn, Cannondale, Pro, Topeak…), or gone out of business entirely (Avocet, Vetta…). And … if you have a manual which is not in our database, please feel free to scan it for us , or send it to us!
We looked high and low to add to our listing of cyclecomputer and bicycle-GPS owner’s manuals. It’s the most complete one you’ll find. We’ve been downloading manuals too so we can still make them available when they are deleted from manufacturer’s Web sites (hello, Vetta…).
We tested three cyclecomputers against one another. Our experiment reveals a lot about their inner workings. Differences in some of their readings were large enough to matter. Read about this in our new article.
New page about the history of distance and speed measurement on bicycles, and the limitations of accuracy in measurement. Did you know that GPS readings wander, so you can rack up some distance even if you are standing still?
Our pages of cyclecomputer instructions have now been brought completely up to date, with links to user manuals for almost every make and model, including GPS. These pages are a unique resource.
