4.6.9 Brakes — Heat-resistance test

4.6.9.1 General

This test applies to all disc and hub brakes, but it applies to rim brakes only where they are known or
suspected to be manufactured from or include thermoplastic materials.

Each brake on the bicycle shall be tested individually, but where the front and rear brakes are identical,
only one brake needs to be tested.

4.6.9.2 Requirement

Throughout the test described in TBIS 4210-4:2017, 4.7, the brake lever shall not touch the
handlebar grip, the operating force shall not exceed 180 N, and the braking force shall not deviate
outside the range 60 N to 115 N.

Immediately after having been subjected to the test described in TBIS 4210-4:2017, 4.7, the brakes
shall achieve at least 70 % of the braking performance which was recorded at the highest operating
force used during the performance tests TBIS 4210-4:2017, 4.6.5.7 c) items 1) and 2).

4.7 Steering

4.7.1 Handlebar — Dimensions

The handlebar shall have an overall width between 350 mm and 1 000 mm unless national regulations
dictate otherwise. Adjust the handlebar height to its highest normal riding position and the saddle to
its lowest normal riding position as specified by the manufacturer [see Clause 5 item c)]. Measure the
vertical distance from the centre and top of the handlebar grips to a point where the saddle surface is
intersected by the seat post axis (see Figure 3). This dimension shall not exceed 400 mm.
