4.3.8.8 Tensile test for a non-welded fork

4.3.8.8.1 General

This test is for forks where the blades and/or the fork steerer are secured in the
fork-crown by press-fitting, clamping, adhesives, or any method other than brazing

or welding.

NOTE It may be convenient to combine this test with the wheel retention test, 4.3.9.4.2.
4.3.8.8.2 Requirement

When tested by the method described in 4.3.8.8.3, there shall be no detachment or
loosening of any parts of the assembly.

4.3.8.8.3 Test method

Mount the fork steerer securely in a suitable rigid mount, keeping any clamping

forces away from the fork-crown, and apply a tensile force of 5 000 N distributed
equally to both drop-outs for 1 min in a direction parallel to the axis of the fork
steerer
