effect of the brakes.
The wheel rim is mechanically most highly stressed when cycling over uneven ground and when
braking. Friction as a result of braking causes wear of the rims. As soon as the wear on the rim reaches
certain limit values, the rim may start to deform under the pressure of the tyre. If in doubt contact your
retailer and ask them to check the thickness of the rim. Some modern rims are fitted with so-called wear
indicators by means of which critical wear of the rim is visible.
