What is a good gear ratio for hill climbing?
In other words, 46 to 49 on the chainring and 16 to 18 on the cassette will meet most people’s needs. If you don’t want to stray out too far, a 46/17 to 42/17 are good gear ratios for smaller and occasional hills. These gear rates are considered a good middle ground that can be used in flat and hilly areas.
What is the easiest gear on a bike?
Low Gear. The low gear is the “easy” gear and is primarily used when climbing. The low gear is the smallest chain ring in the front, and the largest cog on the rear cassette. In this position pedaling will be easiest and the least amount of force will be required to push the pedals.
What gear ratio is best for speed?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.
How many gears do I need for hills?
You only need 1 gear
Even a single speed bike will move you faster with less effort than walking – bicycles are efficient machines. Sheldon pointed out that if you come across a hill that’s too steep you could get off and push. So you only need one gear, unless…
How do I know what gear ratio I need?
To find the gear ratio, divide the big number by the little number. In the example to the left, 37 ÷ 12 = 3.083333. These are 3.08 gears.
