What are chain rings?
Chainrings are the parts with the teeth on the chainset over which the chain passes. They can wear out over time but they are available to buy individually. You don’t have to buy a whole new chainset just because a chainring has worn out. Chainrings are quite easy to replace too.

What is the purpose of an oval chainring?
Oval chainrings maximize the part of the stroke where power is produced and minimize resistance where it isn’t.

What is BCD chainring?
Bolt Circle Diameter (BCD) is the diameter of the circle that goes through the center of all of the bolts on your chainring. On bicycle chainrings, this dimension is usually measured in millimeters. It is critical to know the BCD of your crankset when you are selecting a new chainring for your bike.

What is the hardest gear on a bike?

What is a crank bolt?

How is road bike power measured?
Power = Force x Distance / Time
For a power meter to work on a bike, it has to measure the amount of force a rider is generating, and how fast that force moves (speed = distance / time). When pedaling a bike, the force comes from the torque produced by a rider’s legs pushing down on the pedals.
