What's new at sheldonbrown.com
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.
Links to instruction sheets for many more bicycle computers have been added to the computer calibration instruction page
