To check a part for loss of rigidity (ﬂex test)

Use the part in a normal manner (without actually rid-

ing) while someone watches carefully for unexpected
movement.

As an example, if you suspect a composite seatpost has
been damaged, sit gently on the saddle while someone
watches to see if the seatpost ﬂexes.

If the helper sees the part ﬂex unexpectedly, or if the
part feels less rigid than it should be, do not ride the
bike. Take the bike to your dealer for replacement or
further inspection.
