GEARS
The gearing system on a bicycle allows the rider to maintain an efficient pedaling cadence across a wide range of speeds and gradients. By shifting gears, the rider can tackle steep hills with ease or pedal at high speed on flat roads.
How Gears Work
Power from the pedals is transmitted via the chain from the front chainrings (crankset) to the rear cogs (cassette). The gear ratio is determined by the relationship between the number of teeth on the front chainring and the rear cog. A large chainring combined with a small rear cog produces a high gear (fast, hard pedaling). A small chainring with a large rear cog produces a low gear (slow, easy pedaling).
Front Shifter (Front Derailleur)
Controls the chain between the front chainrings. On a bike with 2 or 3 chainrings, this makes large jumps in gear ratio. Traditionally operated by the left shifter on the handlebars.
Rear Shifter (Rear Derailleur)
Controls the chain between the cogs on the rear cassette. Provides smaller, more frequent gear changes for fine-tuning the gear ratio to the terrain. Operated by the right shifter on the handlebars.
How to Shift
- Shift before you need to, not when you are already struggling.
- Always pedal when shifting to allow the chain to move smoothly between gears.
- Avoid cross-chaining (using the smallest chainring with the smallest cog, or the largest chainring with the largest cog).
Gear Numbering
The total number of gears is calculated by multiplying the number of front chainrings by the number of rear cogs. For example, a 2x11 drivetrain has 22 gears (though some overlap between the ratios means the effective number of distinct gears is somewhat less).

Önemli olan bisikletin kaç vitesli olduğu değil, vitesin kuvvet kazancıdır, yani dişli oranları ve dişlilerin tırnak sayılarıdır. Aynakol küçük dişlisi ne kadar küçük, ruble büyük dişlisi ne kadar büyük olursa rampa tırmanışları o kadar kolay olur.
