What does a rear derailleur do?
|
|
The rear derailleur is designed to move the chain up and down on the sprockets (or cogs) connected to your rear hub. Together these cogs are known as the rear cassette. By moving to a cog with fewer teeth, the derailleur gives the rider a faster (or higher) gear which is appropriate for flat areas or descents. By moving to a cog with more teeth, the derailleur offers a gear more appropriate for climbing hills (or a lower gear).

What is a chainring?
|
|
Chainrings are the one, two or three large sprockets attached to the drive side of your crankset. Shifting from one chainring to another gives you different gearing options while riding.
|
|
|
|
|
A chainring is ready to be replaced when its teeth have become worn from use. Typical signs of the need for replacement are slippage of the chain and (rarely) excessive noise.

How do I know when to true the wheels on my bike?
|
|
Lift your wheel off the ground and give it a spin. If the wheel wobbles back and forth or up and down, it’s time to true it. Wheels come out of true through regular use. The rim is held at the correct angle to the hub by the pull of the spokes in equal directions. Hopping curbs, hitting rocks and the general punishment a bicycle endures is enough to knock a wheel out of true.

What kind of headset do I have?
|
|
A threaded headset gets its name from the threaded steerer tube at the top of a fork. The steerer tube is attached to the inside head tube on a frame with an adjustable race. A threaded headset can be identified easily by the quill-type stem that fits inside the steerer tube. This article will discuss repairs and adjustments of a threaded headset.
