  Speeds refers to the number of gears, which is determined by how many cogs are on a cassette.

• Gearing
  10-51 teeth
• Gear ratio
  510%

  Gear ratio shows the size of the gap between the largest and smallest cogs. When the difference is large, riders have access to both very hard and very easy gears; a smaller difference results in closer gear spacing, making it simpler to maintain a comfortable cadence. Also, keep in mind that the number of cogs (speeds) impacts how much each gear differs from the next.

  10 teeth
• Largest cog
  51 teeth
