4.3.15.4 Saddle – Static strength test
4.3.15.4.1 Requirement
When tested by the method described in 4.3.15.4.2, the saddle cover and/or plastic
moulding shall not disengage from the chassis of the saddle, and there shall be no
cracking or permanent.
4.3.15.4.2 Test method
With the saddle positioned in a suitable fixture representative of a seat-post clamp
assembly and in a maximum rearward direction as defined by the saddle
manufacturer’s rail markings or instructions, and the clamps tightened to the torque
recommended by the bicycle manufacturer, apply forces F20 of 440 N in turn under
the rear and nose of the saddle cover, as shown in Figure 49, ensuring that the force
is not applied to any part of the chassis of the saddle. The load application point is on
the longitudinal plane of the saddle at 25 mm from the back (/front) of the saddle. If
the saddle design is such that it cannot accept a centreline load application, the load
shall be symmetrically applied at two points of the saddle.
NOTE Loading on the rear of the saddle is required to be symmetrical about its longitudinal
axis, as shown in Figure 50.
