I have some chromed steel risers on my fixed gear- I fished them out of the junk bin at my LBS. Cut down and oury'd, they are supremely comfortable, and they cut a nice rakish line with my ol-skool road quill stem.

There are times I find myself hunching down to get a little more aero and wish I had someplace to go- I just rescued an old pair of bar ends from my rusting MTB and may chop them down and put them to new use.

I cut the bars down a little overzealously so there's not tons to crank on when climbing but it's manageable nonetheless. Risers, HOooo!
