calc_skids: Skid patches

In jannes-m/velo: An R package for bicycle-related calculations

Skid patches

Description

The function calc_skids calculates the number of skid patches for both single-legged and two-legged skidders for specified combinations of chainring- and cog-teeth.

Usage

calc_skids(front, rear)

Arguments

front	The number of chainring teeth.
rear	The number of cog teeths.

Details

The function was inspired by http://www.bikecalc.com/skid_patch_math. Basically, the function divides the cog by the the least common denominator of cog and chainring teeth. This corresponds to the number of skid patches for single-legged skidders. As an extra, the function also calculates the number of skid patches for ambidextrous skidders.

Value

The function returns a data.frame with two columns:

1. skid_1 The number of skid patches for single-legged skidders.

2. skid_2 The number of skid patches for ambidextrous skidders (two-legged skidders).

Examples

calc_skids(54, 14)
# you can also specify vectors of length > 1
calc_skids(front = 48:54,
           rear = 12:18)
