I'm running 48cm noodles on the bike that I put most of my miles on. In my opinion they're easily the most comfortable drop bars ever designed (well... at least that I've tried). They have a nice, wide top section that provides plenty of room for your hands. The "flat ramp" behind the brake hoods makes for a really comfortable and natural hand position. And the way the drops flare out makes the drops very accessable. I don't "get" the ergo bends that all of the modern drop bars have. I think it was a step in the wrong direction. Anyway, don't hesitate to pick-up the noodles. Most everyone that I know of that has tried them has been really happy with them.
