i ve never had problems with the onza's, but i m also a careful rider. friends killed them too above the pad-holder. and they were bad done (sharp edge) so it s natural that they gona brake someday...maybe just a bad lot or an other issue of "prototyping" ?
i need a "v-brake" at the front, so i use the paul motolites. at the back i ve got campa or / paul stoplights.
at the bike which i just use to look at it are devil-cantis mounted, imo the cooooolest looking brake
other very nice brakes
-wiesmann
-biedler speedkiller
-rpm speedcrusher
-marinovative cheap trick
-trailborn
-gravity research
-ird
-wtb speedmaster
-and the one which everyone mentioned, the avid tri align 2
if u re looking for smt very strong take some forged ones like the shimano's or dia-compes.
and about the campa or for 230$...ebay goes sometimes strange ways, i m shure if u aren t in a hurry u ll find a pair for less than the half...
ride on
