Page "Cycling" Paragraph 11

The drivetrain components of the bike should also be considered.

A middle grade dérailleur is sufficient for a beginner, although many utility bikes come equipped with hub gears.

If the rider plans a significant amount of hillclimbing, a triple-crank ( three chainrings ) front gear system may be preferred.

Otherwise, the relatively lighter and less expensive two chainrings may be better.

Much simpler fixed wheel bikes are also available, and may be more suitable for commuters.
