Hi Cellarman,From the info I've gained from other posters, I've made a note that someone has measured the rise (measurement C) of the stock bars as between 40 to 50 mm, whereas the 755's would be 85mm. Others have pointed out the fact that in choosing higher than stock bars, could present a problem regarding cable lengths etc.The 755 appears to also be referred to as Road Medium.Hope this helps.
Mine aren't even on the list above! The ones that are fitted to mine are 664! Don't know what to make of that!!!
