2. Bottom bracket - Wikipedia

   en.wikipedia.org/wiki/Bottom_bracket

   The bottom bracket is pressed directly into the frame. Using pressed in standards allows frame manufacturers greater flexibility in the frame design, and can offer greater stiffness and reduced mass. A disadvantage is that assembly and disassembly of press-fit bottom bracket bearings require expensive special equipment.

3. Headset (bicycle part) - Wikipedia

   en.wikipedia.org/wiki/Headset_(bicycle_part)

   A less common headset failure is really a frame failure. The head tube can stretch, allowing a headset cup, which is supposed to be a tight interference fit, to become loose in the tube. Lugless frames are most vulnerable; in a lugged frame the lug reinforces the top and bottom of the head tube and generally prevents stretching of this type.

4. Crankset - Wikipedia

   en.wikipedia.org/wiki/Crankset

   Even newer designs have the bottom bracket spindle, usually hollow and larger diameter than is possible for bottom brackets with bearings held inside the bottom bracket shell of a bike frame, for reduced weight and increased stiffness, permanently attached to the right crank (Shimano and others) or the left crank (Race Face).

5. Bicycle frame - Wikipedia

   en.wikipedia.org/wiki/Bicycle_frame

   The bottom bracket shell is a short and large diameter tube, relative to the other tubes in the frame, that runs side to side and holds the bottom bracket. It is usually threaded, often left-hand threaded on the right (drive) side of the bike to prevent loosening by fretting induced precession , and right-hand threaded on the left (non-drive) side.

6. Interference fit - Wikipedia

   en.wikipedia.org/wiki/Interference_fit

   Press fit is achieved with presses that can press the parts together with very large amounts of force. The presses are generally hydraulic , although small hand-operated presses (such as arbor presses ) may operate by means of the mechanical advantage supplied by a jackscrew or by a gear reduction driving a rack and pinion .
