i had pulsing initially running these rotors with deore calipers. when i put my xt calipers on it was still there. i had been running a 7" rotor with a 160R adaptor which meant the offset was very slightly incorrect (a few mm). i put the correct adaptor on (a proper shimano 180F) and the problem disappeared within a few rides.Broseph said:get the alligators if you can deal with some brake pad pulsing. i've had them front and back and i replaced the front with an xtr because i can't deal with the pulse. i don't notice it much in the back for some reason.
Not exactly true. While the grades can even be similar, manufacturing techniques first put different stresses in order to make different designs, along with the amount of braking surface area. Additionally, we're also finding out that some don't seem to be heat treated in manufacturing, thus being prone to warpage during use. Some designs also don't have heat capacities of others, and so on.LMN said:Stainless steel are created pretty well equally now a days.
