Riser Bars or Flat Bars?

[SalsaMTB]

I prefer flat bar, but I'm currently riding a light weight fully rigid bike. I've always preferred flat though because they're typically narrower.

I find with flat bars, I'm more likely to pitch forward or go over the bars in technical areas. Mainly a matter of preference, though. And you can trim them down (I think the majority of people do), if they're too wide. Wide equals good for opening up your chest to breathe, but bad for narrow singletrack (I've certainly found this out the hard way!).
