Mavic wear indicators

Mavic wear indicators

I have Mavic A719 wheel rims which have done about 4,500 miles. I have noticed particularly on the front wheel there is wear on the on the braking surface of the rims. Mavic indicate on their website there are wear indicators on the inside of the rim but I am unable to find them.

I should be pleased if you can advise how I can find the indicators or assess how much wear has taken place so that a decision can be made as to whether the rims need replacing.

Mavic cut a notch, about 1mm deep, into the inside of each tyre retaining flange, at one place on the circumference. When brake wear has removed all but 1mm of metal from the outside of those flanges, small holes will appear in the braking surfaces at this location, first one side, then the other.

The place to look out for these holes is indicated either on the rim decal or notches cut in the outside of the rim, just above where the holes will eventually appear. If in doubt (a decal may peel off), remove the tyre and search inside the rim for those internal notches. Then put your own mark on the outside.
