## How many gears does an 11 speed bike have?

That means the outer ring has 50 teeth and the inner ring has 34 teeth. The rear cassette is 11 speed 11-32. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32).

## How do you read a gear ratio?

The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion). So, if the ring gear has 37 teeth and the pinion has 9 teeth, the ratio is 4.11:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.

## What gear should I use on a flat road?

When riding on flat terrain, it’s best to use the middle or big front chainring and a range of rear cogs. You also want to avoid cross-chaining, where the chain is at an extreme slant either in the big ring up front and the biggest cog in back, or the small ring up front and the small cog in back.
