Explanations: answer key for all 10 questions

Q1: How is a basic gear ratio found?
Answer: Front chainring teeth divided by rear cog teeth
A 50 to 25 setup is 2 to 1.
Q2: With a 2 to 1 ratio, how often does the wheel turn per pedal turn?
Answer: Twice
Higher ratios move you farther.
Q3: Which combination is easiest for climbing?
Answer: Small chainring and large rear cog
It lowers the gear ratio.
Q4: Which combination suits fast riding on flat roads?
Answer: Large chainring and small rear cog
Each pedal stroke goes farther.
Q5: What does a derailleur do?
Answer: Moves the chain between sprockets
Bikes may have front and rear ones.
Q6: What is cadence?
Answer: Pedal revolutions per minute
Many riders aim for 80 to 100.
Q7: Why do riders avoid big chainring with big cog?
Answer: The chain runs at a harsh angle
This is called cross-chaining.
Q8: Where are gears hidden on an internal hub bike?
Answer: Inside the rear wheel hub
Sturmey-Archer made famous three-speeds.
Q9: What is special about a fixed-gear bike?
Answer: The pedals turn whenever the wheel turns
Riders cannot coast.
Q10: What do electronic groupsets use to shift?
Answer: Small motors triggered by buttons
Shimano Di2 is one example.

Bicycle Gears Quiz – Gear Ratios, Cadence and Derailleurs

A bicycle's gears link the chainring at the pedals to cogs on the rear wheel. The gear ratio is the number of chainring teeth divided by cog teeth, so a 50-tooth ring with a 25-tooth cog turns the wheel twice per pedal stroke.

A small chainring with a large cog gives a low gear for climbing, while a large chainring with a small cog suits speed. Derailleurs move the chain between sprockets so riders can keep a comfortable cadence.

Riders avoid cross-chaining, which strains the chain. Some bikes hide gears inside the rear hub, fixed-gear bikes have just one, and electronic systems now shift with small motors.

Did You Know?

Tullio Campagnolo helped popularize quick releases and derailleurs.
Modern road bikes may have 24 gears or more.
1x drivetrains use a single chainring.
Smooth shifting needs a clean chain.
Track bikes in velodromes use fixed gears.
