I have always run 7 and 8speed on my bikes which I suppose is a bit retro these days.I am building up my new bike and want some 8speed shifter/brake xtr combo units.I have been looking on evilbay and the choice is between m950 and m951 .Can anyone tell me the difference between the two , years of manufacture ,preferences, etc .I will be running these with xtr m900 front and rear mechs .Any info much appreciated.
Regards Colin.
