as far as yumeya goes, i think they might aswel called it youminger, i think it looks chavtastic, white and gold the 2 most recent fashion colours in bikes together, very over the top i think.
as far as xtr goes, i used to run full m900 back in the day, then started picking an choosing bits after that, never really liked the m950/2 stuff so only ran the shifters and mechs and v brakes, these days it's pretty much just the shifters and mechs, brakes are hope or whatever.
i definately think the rear mech is better than xt, mainly because of the jockey wheels lasting longer but i don't like the new xtr shifters, the action is too light and you can blow through extra gears unintentionally so i've stuck with the older ones. i do except the prices are stupid though, but then xo is daft money, so by comparison xtr has been cheap for a while and it's just caught up, don't forget they have upgraded it with carbon etc.
but i would never run the sram system, having worked in a shop and worked on that stuff i just think the shift is too clunky, the mechs bend and break too easily, the cables on some models are a sod to fit, and i think it looks over engineered to save weight, week and ugly.
You have enemies? Good. That means you've stood up for something in your life.
