So, the Avid "road" lever mechanical disk is the BB5? At any rate, ascpgh and so forth (please include name!) confirms my experience that they aren't worth -- well, pick a noun denominating bulk of little value.
I like disks because I switch between rims of 44 mm and 27 mm outside width; also, tho' we don't get much rain here, when we do, it combines with the ominipresent dust and fine sand to make a grinding fluid that will score your rims very quickly. Just wish I could figure out how to adjust those Tektro V-brake interrupters.
