Before I do that though, I want to determine if a problem I'm having with the RSX shifter is a simple maintenance issue, or a bigger problem. On the left shifter, the lever that clicks the gears from a larger ring to a smaller ring usually does not work. The lever moves but does not engage the mechanism to index the gear; it just moves freely. With just the right pressure on the larger brake lever and a little luck, the smaller lever will occassionally engage and shift the gear. If I go ahead with changing the handlebars, I'll have my LBS do that work. But before I cart the two bikes there and have them tear into it, I would just like to know if this is a simple fix.

Thanks!
