Is there a huge performance difference between the two? Does the difference in cost justify the difference in performance? I'm in the slow process of building up a new DH race bike and am trying to make it as cheap as possible while still remaining relatively light. Jenson has LX brakes for $32.50 per caliper, versus $69 for the Saint. Either of these will likely need adaptors and rotors to work for my application. I have a set of LX's on my DJ bike, but want some input as to how they'll perform on a DH bike with 8" rotors. Or do I skip that and go for Saints? Thanks in advance.
