|Servicing Cup and Cone Hubs||For all cyclists.|
This article examines the workings of conventional bicycle hubs and explains the tools and techniques involved in servicing them.
It also describes a special tool I invented to facilitate bearing adjustment on quick-release hubs...you can make your own from junk parts.
|Color Coding Your Tools||For shop mechanics and serious home mechanics.|
We use a simple color coding system for wrench sizes. It is a great time saver around the shop, because it allows the mechanics to tell the size of a wrench at a glance, even from across the room.
|Cantilever Adjustment||For any cyclist who wants to service cantilever brakes.|
A general article on practical aspects of brake adjustment, specifically focussing on cantilever brakes (including the new "V-type" cantilevers.)
|Cables||For anyone who services bicycle brakes or gears.|
Most brake and gear shifting problems are the result of cable friction or misadjustment. This article covers cable installation, preparation, and maintenance.
|Fixing Freewheels||For hard-core do-it-yourselfers.|
I advise against taking freewheels apart for service, but if you insist, here's how...don't say I didn't warn you!
|Stuck Seatposts||For people who forgot to grease their seatposts.|
Techniques and strategies for freeing up seatposts that are corroded in place.
|Straightening Chainwheels||For the advanced home mechanic or shop mechanic.|
If your chainwheels are bent, your front derailer can't work properly. This short article deals with strategies for straightening them out.
|Derailer Adjustment||A step-by-step guide for the home or shop mechanic.|
How to adjust your bicycle's derailers for smooth, reliable shifting.
|One Piece Cranks|
One-piece cranks are mainly found on older American-made bicycles, and children's bicycles made for the U.S. market. One piece cranks use a single metal forging as left crank, right crank and bottom-bracket axle.
Many older bicycles use wedge-shaped fasteners called "cotters" to hold the cranks onto the bottom-bracket axle.
These cotters have a nut to hold them in place after they have been driven or pressed in.
They can be difficult to remove, especially if they have been in place for a long time.
Many younger mechanics are unfamiliar with some of the idiosyncrasies of English-made 3-speed bikes. Nevertheless, there are an awful lot of them still on the road, because they were built to last, and they still come in for repair. An all-around bike mechanic should be up to speed on these bikes. These bikes are actually very easy to work on, but you do need to know a few of their quirks.
|Tandem Synch Chains||For home and shop mechanics.|
The synchronizing chain on a tandem is usually adjusted by an eccentric-mounted bottom bracket at one end or the other. When you service a tandem, or, especially, when you set up a new one, you may notice that the tension on the synchronizing chain varies as the cranks turn. It may be quite tight when the cranks are in one position, and rather droopy after the cranks have rotated a bit. This is not good.
Now with more tips on eccentrics and chainwheel selection. (August 8, 1997)
|Tire Sizing||For everyone who buys tires.|
Bicycle tires come in a bewildering variety of sizes. To make matters worse, in the early days of cycling, every country that manufactured bicycles developed its own system of marking the sizes. These different national sizing schemes created a situation in which the same size tire would be known by different numbers in different countries. Even worse, different-sized tires that were not interchangeable with one another were often marked with the same numbers!
|Tire Rotation||Should you rotate your tires?|
This seems like a good idea at first, but you really shouldn't do it! This short article explains why.
|Tool Tips:||A Blast from the Past!|
In the 1980s, I wrote a regular monthly column in Bicycling magazine, on maintenance and repair, particularly focussed on the selection and use of tools. While some of this material is rather dated, much of it isn't. Since some of these articles deal with topics that are not covered in such depth elsewhere in this site, I'm putting them online.
|Nutdrivers||Cone Wrenches||Cottered Crank|
|Wheelbuilding||You can learn to build your own wheels!|
This article provides all you need to know to build your own bicycle wheels. A knowledge of wheelbuilding can be invaluable to any cyclist who wishes to do his or her own maintenance and repair.
Building wheels from scratch is the best way to learn the craft of wheel truing, to get the feel for how a wheel responds to spoke adjustments. It is much easier to learn this with new, un-damaged parts than to start right in trying to repair damaged wheels.
