I had one of those on a B4 frame. The entire bike was noodly. I recall reading a magazine review (Mountain Bike Action?) that said it felt like riding a motorcycle. Yeeeeeahhhh, motorcycle.
But your frame has held up.I think the new Shimano stuff is overhyped. My XTR cassette makes weird noises. My XT shifter is stiff and uncomfortable. My NDS XT crank arm came loose after 7 months of riding. My XT 8120 brakes of the same age also will need a bleed soon (My Codes that are a year older are still going strong).
