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…).

Cyclecomputer math: how accurate?
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.
How bicycle spokes transmit torque between hub and rim
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.
New video about brake quick releases
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.
Update to internal-gear cable-pull page
Our page listing internal-gear-hub cable pulls lengths is now updated to cover the new Sturmey-Archer rotary (pulley) shifting 3-speeds.
Damon Rinard pages edited, updated, reformatted
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.
Creaks, Clicks and Clunks — and Rubs and Lurches and Rattles
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…
Cable-pull adapters update
We do minor updates on an ongoing basis and often don’t announce them. Latest is to the cribsheet on cable-pull adapters.
Major updates to the headsets page
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!
Update to 5-speed hub information
Our Sturmey-Archer 4, 5 and 7-speed hub page has been updated with links to newly-available information on recent 5-speed hubs.
