Technology can just get to be too much. Do you lose valuable riding time fiddling with your phone or GPS device? Bet you do. The battery will run out, sooner or later. On some unfamiliar backroad. Off-roading deep in the forest. Navigating a thicket of congested urban streets.

Additions to the page about LED headlights — lots of new information, about why lights which are well-designed for nighttime use can be good as daytime running lights, but some that are impressive in daylight don’t do so well at night; about ultra-cheap lights, how to make them pay for themselves adn which kind is preferable; installation and adjustment.
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.
The Sheldon Brown gear calculator is updated and improved: more tire sizes are covered including fatbikes, 29ers, 29+ and monster bikes, and we now have a version in German, as well as French.
New article on riding with the RideWithGPS app. What you need to know to get started: mounting your phone, keeping it charged, downloading routes, and recording your rides.
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.
John Allen has done some revisions to the articles on tires/tyres and added more information on GPS to the article on cyclecomputer calibration.
