4.6 Braking performance

4.6.1 Test bicycle

Conduct the braking performance test on a fully assembled bicycle after the brakes have been subjected
to the strength test detailed in TBIS 4210-2:2017, 4.6.6, and 4.6.7. Before testing the bicycle by
either method, inflate the tyres and adjust the brakes according to the manufacturer’s instructions. In
the case of rim-brakes, adjust it to the maximum clearance specified by the manufacturer.

4.6.2 Secondary brake levers

Where a bicycle is fitted with secondary brake levers attached to brake levers, bar-ends, or aerodynamic
extensions, separate tests shall be conducted for the operation of the secondary brake levers in addition
to tests with the normal levers.
