How did you take notice of this problem?
DIRK ZEDLER, bike-expert and TOUR-editor:
Some reader's letters drew our attention the hard Shimano-Dura-Ace-brake pads eating into the rim and subsequently conducted tests ourselves which confirmed the eating into the rims at high speed and when braking hard. By doing so, partly outrageously expensive rims were destroyed. (...)
How did retailers deal with it? (...)
Since 1996 we have been pointing out in several publications that rims, ie, brake pads should only to be considered coherently and that they are subject to wear and tear. And we called on the manufacturers to cooperate. This attempt to sentizise them apparently deflagrated unheard. Otherwise, we would not be sitting here. (...)
How does Magura inform its customers about which pad matches which rim? (...)
According to our research work, the stress arising in the high-end-sector in practice, which is way higher than stipulated in the DIN-standard, cannot be simulated on any testing device existing in Germany at the moment. In order to do so, you first of all would have to construct test stands able to simulate speeds of more than 70 km/h and the subsequent slowing down before riding through a downhill bend.
