CORRECT FRAME SIZE
When selecting a new bicycle, the correct choice of frame size is a very important safety consideration. Most full sized bicycles come in
a range of frame sizes. These sizes usually refer to the distance between the center of the bottom bracket and the top of the frame seat
tube.
For safe and comfortable riding there should be a clearance of between 25mm and 50mm between the groin area of
the intended rider and the top tube of the bicycle frame, while the rider straddles the bicycle with both feet flat on
the ground.
The ideal clearance will vary between types of bicycles and rider preference. This makes straddling the frame when off the saddle easier
and safer in situations such as sudden traffic stops. Women can use a men’s style bicycle to determine the correct size of the women’s
model.
The following chart and diagram will help you make the correct choice.
