Question regarding these. I have a Specialized Sirrus '05 with stock straight handle bars. I'm considering these for more hand positions on longer rides. I don't really know much about mechanics yet. The bike has Shimano brake/shift assembly, the type with seperate levers to shift up and down (rapidfire I think they're called?). Anyway, would there be any issue mounting those on this bar?

Further, to mount them I'm guessing this is what you would need to do... Release the bolts holding the top of the stem together to release the current bar and release the bolts on the bottom of the shifter assembly to release those. Then place the new bars in place and replace the bolts. Is that correct? Any assistantance would be appriciated. Also, anything else to consider when changing out the handlebars, i.e. bar diameter or anything a problem?
