4.3.8.5.4 Test method 2

a) This test is described in 4.3.8.5.3

b) This test is similar to that described in 4.3.8.5.3 except that the dropping height
shall be increased to 600 mm instead that given in Table 18. The section applies to

forks in 4.3.8.5.1.2.
c) Apply a torque of T3 to the assembly and maintain for 1 min in each direction of
possible rotation about the steerer axis. The torque is given in Table 19, and a
typical example of test equipment is illustrated in Figure 27.

Table 19 — Torque on fork

Torque, T3 80 Nm

1 Front fork
2 Fork mounting fixture (Fixture representative of the head-tube)
3 Rigid mount
4 Test adaptor
