Have been riding/racing/training since the 70's and logged an awful lot of miles and busted scores of rims....mostly due to spokes pulling thru, and race damage.... even lost a few rims when my wheels found a deep sharp pot-hole hidden in a puddle....funny, but in all that time have never ever sustained enough damage to the side-walls of a rim to retire it ( and frankly this hasn't happened much over time within a rather large circle of fellow cyclists I have been around over the years....admittedly this does happen but then so do flats...and of course there are maintenance averse cyclists that catch a lot of maintenace averse related "bad luck"...)....and I'm not especially kind to equipment though I do maintain it....warthog101 wrote: ↑Tue Dec 07, 2021 11:29 pmRim brakes aren't too quiet in the wet either.
That grinding sound is your rim being worn away.
And btw compared to discs in the wet as descibed above, rim brakes are dead quiet...though admittedly they occassionaly make noise when applied after they catch a pebble but that is dead easy to diagnose and remedy...but they definitely do not produce a constantly recurring noise ...
Cheers
