Hello, Looking to replace my avid mechanical disc brakes for better power and modulation. Looking at the avid elixir CR: http://www.sram.com/en/avid/hydraulicdiscbrakes/elixircr.php Any comments? My current setup has mechanical 160mm discs and they work well. Im looking to also put chris king hubs on. My wheels are mavic 317 from 2001 or so. Will I see a real difference if I go hydraulic 160mm discs? Do I gain or loose stopping power with hydraulics? Is it smart to go to 185 or 203mm, or is this too much stress on a standard skewer-type hub? I can see using the big ones on through-fork hubs, but not when the connection force is via a skewer system. Thoughts? I can do whatever, but want strong braking power, no loss to a slight gain in performance over the 160mm avid mechanicals, and long life. Is hydraulic where it's at?
