You need to decide which type of bar to use before you buy new brake levers. the straight bars shown take a different lever but if you go with a higher stem & your present bars or the moustach bars, you don't need to buy new levers.

The Nitto Technomic will get your bars up but you need to figure out how much stem extension you need before you buy the Technomic as that high a stem will require more extension just to keep the bars where they are, remember that as stem length is increased, you need more extension because of the angle.

Finally, if money is tight, you can find an SR stem that was used with the long SunTour stemshifters. They are long enough to get your bars up near saddle height & won't be very expensive. Let us know how things go. Don
