Seriously, I’m not being either contentious or finicky, just asking what seems to me to be a perfectly reasonable question, based on the consideration that pads that grip rims more strongly might also wear them more quickly.
First of all, I'll admit to not using these brake pads, so I have zero empirical evidence one way or another. However, I don't know if I agree with the claim that "pads that grip rims more strongly might also wear them more quickly". My own experience is brake pads used in the dry doesn't wear down aluminum rims appreciably, even with thousands of miles of use. In fact, I have wheels that have seen tens of thousands of miles in mostly fair weather conditions with both Campagnolo and Koolstop pads, and they don't have that concave rim wall indicative of excessive wear (and I have an inexpensive specialized gauge <https://www.google.com/search?q=Iwanson+gauge> for this). Rims do wear quite a bit more when run in wet conditions, when grit comes into play, when grit embed themselves into the (soft) brake pads; no less than Jobst Brandt has opined on this topic <https://yarchive.net/bike/rim_wear.html>. So maybe the biggest contributor to rim wear isn't the gripping force, but under what conditions the wheels are used in and secondarily the type of brake pad material? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
