Composite material failures.

Failure of Carbon Fibre Reinforced Polymer (CFRP) cycle frames

 

Select pictures below for larger images.

Although very strong and very stiff in theory, several catastrophic failures of carbon frames have been reported in accidents.
In some, the wheels have survived intact but the frame has failed. Many experienced riders have reported that a metal frame would have survived intact. Such damaged frames are usually replaced under warranty

The seatstays in the vicinity of the rear brake wishbone and the chain stays appear to be the most susceptible points, see the next page for why.
