Frame problems are not common, but as an example, some riders could get a

bicycle. Transport your bicycle directly to a dealer for inspection and repair.
WARNING
A frame or fork problem could decrease your control and cause you to fall. If your bicycle
gets a shimmy or any other problem, decrease your speed immediately. Transport your
bicycle to your dealer for inspection and repair.
Life span of a bicycle and its parts

parts can be drastically reduced and may fail without warning.
The safe life of a part is determined by its construction, materials, use, maintenance,
rider weight, speed, terrain, and environment (humidity, salinity, temperature, etc.), so
it is not possible to give an accurate timetable for replacement. Any form of crack,
