Saddle

1. Bicycle Saddle

A saddle is the seat of a bicycle, designed to support the rider. It is typically mounted on the seat post and may include padding, springs, or gel inserts for comfort. Bicycle saddles vary in shape and construction depending on the type of bike and intended use (e.g., racing, touring, or commuting).

  • Gel saddle: Contains gel padding for enhanced comfort and shock absorption.

2. Brake Saddle

In the context of centerpull bicycle brakes, the saddle is the metal piece that connects the two brake arms via a straddle cable. When tension is applied (typically by a brake lever), the saddle helps pull both arms inward to engage the brake pads against the rim.

3. Upper Main Bearing Saddle

In automotive and mechanical engineering, a saddle may also refer to the upper main bearing seat in an engine block or machinery. This is the precisely machined surface that supports the upper half of a main bearing shell, helping align and secure the crankshaft or rotating component.
