get_st_to_rear_tire_clearance: Get seat tube to rear tire clearance

In ghuiber/bicycle: Design a bicycle frame

Description

Frame designs with shorter chain stays are for racing; longer chain stays are for comfort. You can tell them apart because the latter have a larger gap between the rear tire and the seat tube. This function returns that gap, in millimeters, for a given design tibble df and wheel diameter.

Usage

get_st_to_rear_tire_clearance(df, wheel_diameter = 622)

Arguments

df	A tibble with frame dimensions from the front and rear triangle, returned by wrap_frame_dims() or at a minimum the portion of it that comes from get_rear_triangle_dims()
wheel_diameter	Wheel diameter in millimeters; 622 is the bead seat diameter of a 700c wheel. To see the effect of the tire width, add 2 x tire width in millimeters – i.e. specify wheel_diameter = 622 + 2 * 32 for a 32 mm tire.

Value

A scalar, the seat tube to rear tire clearance in millimeters
