As mentioned earlier, I’m a systems guy with respect to bike components, and that penchant is implemented relative to the importance of the component. A lockring or expander bolt has more off-brand freedom than a crankset. Having said that, I put some brakes on my road bike last summer, made not by Shimano, but by ee Cycleworks out of California. These are absolutely the best things I have ever squeezed (on a road bike). And, not that I’m a weight weenie, but they weigh a paltry 169 grams to Sram Red’s 250, Campy’s Super Record 275, or Dura Ace 9000′s 296 End of story.
