Osman analyzes data from over 1000 of his own bicycle rides to see what they show, and describes what might be discovered by mining the huge troves of data held by Strava, RidewithGPS and other GPS-based mapping services. Osman makes a particularly trenchant suggestion for e-bike design based on his analysis, and discusses issues of data privacy. Find this along with Osman’s other articles at https://www.sheldonbrown.com/isvan.html
Sheldon left his article about taping handlebars incomplete. It is completed now, all you might ever want to know and maybe more! https://sheldonbrown.com/handlebar-tape.html
We have expanded our article for individuals selling bicycles and components — which also holds advice for buyers. There is a new section about shipping. This article holds all the basic information you need on where to post an advertisement and how to create it — how to take good photos of the bicycle, and measurements so the buyer will be able to determine whether the bicycle fits.
Sheldonbrown.com technical writer and editor John Allen frequently shoots video from his bicycle using more than one camera; sometimes a separate audio recorder. The output must be synchronized in post production. John has now performed a major update on his article about how to keep the recordings in sync, going so far as creating true surround sound without a surround recorder.
We have updated our page about the different types of bicycle brakes, which added descriptions and several photos illustrating the different types.
John has added quite a bit of text to the cranks page; more about crank length, and an entirely new section on how to check for several kinds of damage; also several illustrations where there were none before.
Thanks to Philip Carlson, our article about 360-degree video now includes a video clip illustrating the nighttime performance of the Garmin VIRB 360 camera. As expected, there is camera-motion blur, but it looks much different from that with a conventional camera.
We have a much expanded description of how to rebuild a freewheel, now a new article and no longer just a paragraph in our main article on freewheels.
Every once in a while we go back and review our pages to deal with product changes and link rot. We just did that with all our pages about Sachs and SRAM internal-gear hubs. You will find product manuals here which are hard to find anywhere else. You can start with our main page about these hubs.
