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.
We have a new article which describes how the spokes transmit pedaling and braking torque between the hub and rim. The spokes do it by changes in tension — but how much does the tension change? The article explains the drawing below.

A brake quick release lets you remove and replace a wheel without deflating the tire. Our new video shows how a brake quick release works. The video appears in our article about flat tires, and the glossary.
Damon Rinard, who now works for Cannondale, had to turn his Web pages about bicycling over to Sheldon Brown back in 2001 when hired by an earlier employer. Rinard’s pages contain a wealth of information on bicycle design, and the renowned Spocalc bicycle spoke length calculator. Rinard even describes how to build a carbon fiber bicycle frame at home, and it’s easier than working with steel. His pages on improving aerodynamics are a real eye-opener. We have improved the translations of several articles originally written in German, checked links and reformatted the pages to make them easier to read in a modern browser.

Information has been added to the Creaks, Clicks and Clunks page to help you diagnose several more problems. The page now covers more types of cranks, the noiseless lurches and bumps which occur due to tire damage, chain too wide for the sprockets, worn-out bottom bracket bearings, chain rub on front derailer…
The headsets page has been updated with much more information on threadless headsets, a description of the Standardized Headset Identification System, advice on mixing and matching headset types, and more!
