Specialized bicycle repair tools are necessary for certain repairs, such as tire levers for changing flat tubes or replacing tires, spoke wrenches and nipple drivers for wheel building, cone wrenches for adjusting wheel hubs, and a headset cup press for pressing unthreaded bearing cups into a bike’s steerer tube. Other tools include derailleur alignment gauges, cassette lock ring tools, bottom bracket pullers, and crank pullers.
Many specially designed bicycle repair tools have been developed to service certain parts of the bicycle. While many repairs can be done with a set of allen wrenches and screwdrivers, other repairs require specially designed tools and cannot be done successfully without them. The most common bicycle repair tools are tire levers, which help the rider lift the tire off the rim to change a flat tube or replace the tire. These levers are made of plastic in most cases to avoid damaging the rim, although metal levers are also available. However, they can damage the rim and are not recommended for most bicycle applications.
Other bike repair tools include spoke wrenches, drag stands, and nipple drivers. These tools are used to build and maintain bicycle wheels. A clamping stand allows a person to gauge how straight and round the wheel is at any given time, and spoke wrenches allow a person to tighten or loosen the spokes if the wheel needs adjustment. A nipple driver is a specially designed tool that helps a person install new spoke nipples quickly and easily. Wheel building is a complex task that requires great skill and practice, and cannot be done well or at all without these bike repair tools.
Cone wrenches are very thin wrenches used to adjust bicycle wheel hubs. The keys are flat to allow one person to work the key in very tight places; The wheel nuts and cones, which press against the bearings inside the hub, are counter-tight against each other, so it can be difficult to get a good grip on these thin nuts. Cone wrenches make this process much easier.
A headset cup press is a device used to press unthreaded bearing cups into a bicycle’s steerer tube. The head tube is the part of the frame that the bicycle fork slides through and is attached to the stem, which in turn is attached to the handlebars. The vise is threaded and puts pressure on the cups as the user threads the handle further and further.
Other bike repair tools include a derailleur alignment gauge, cassette lock ring tools, bottom bracket pullers, crank pullers, and various other specially designed tools. A suspension alignment gauge allows a person to straighten the part of the frame that the rear derailleur is attached to, should it bend. Cassette lock ring tools allow the user to remove the rear gear group. Bottom bracket pullers allow the user to remove or install a bottom bracket, which is a set of bearings at the bottom of the frame. To use this tool, the bicycle cranks must be removed with a crank puller.
