Replace the bars OEM, aftermarket bars, or Clip-ons? Some recomendations please.
I changed to LSL bars which are higher and have less "droop" so they're much more comfortable for long rides and I sit up straighter which is good for the city. Sucks on the track, though. They come in different bends.
Got 'em second-hand on TOB, I think I paid around $50. My guess is that if you want to go OEM there will be take-offs for sale in the parts for sale board as lots of people switch to clipons.
