Article about how to build up a tandem crankset using solo-bike parts. Save money, try different ideas, enjoy…
We have a new page about tubeless tires for bicycles. We aren’t great tubeless-tire fans and we’ll tell you why!
Sheldonbrown.com has compiled links to more cyclecomputer and bicycle GPS manuals, old and new, than you will find anywhere else on the Internet. We have once again added information on new models and re-linked when a brand has discontinued support, left the cyclecomputer business (Blackburn, Cannondale, Pro, Topeak…), or gone out of business entirely (Avocet, Vetta…). And … if you have a manual which is not in our database, please feel free to scan it for us , or send it to us!
New article about drum brakes — how they work, their advantages and disadvantages, installation, maintenance, safety considerations.
We have updated all of our pages about Sachs and SRAM internal-gear hubs, fixing broken links and, regretfully, indicating that SRAM is now no longer making internal-gear hubs. But many of you are using these hubs, and we are maintaining information on them. Main page with links to others.
All of our pages about fixed-gear and singlespeed bicycles have been updated. Information about derailerless drivetrains including workarounds for frames with vertical dropouts has been consolidated in a single article and expanded. Table of contents for these articles.
Pages about tandems and tandeming Sheldon Brown and family on home-built tandems[/caption] have been updated. We have more about disc brakes, brake levers, Gates synchronizing belts, and details about upgrading a cheap beach-resort tandem to ride with a child.
Aluminum, titanium and carbon-fiber frames are fashionable, and generally lighter than steel frames. But if you are on a bicycle tour to a remote area, the ability of any small-town welder to perform an ugly but functional repair on a steel frame could allow you to continue. You may be able to straighten a bent frame yourself. Read about it here.
Bike check — a quick safety check you can do on your bicycle– and more extensive testing too.
