Weird since I bought the BB 6-months ago and it came from QBP or Quintin.

I agree with you that stuff "seems" to be replaced a little more often, but I know quite a few 15,000+ miles a year riders who are riding the same stuff they've been riding for 3-4 years. Since I occasionally work in a shop that caters to real pros that race for a living. I know the abuse the new stuff takes and it really is shocking. It's shocking to see a 5-6 year old Dura-Ace group geting ready to hit 100,000 including the STI levers. . . though the left one may have been replaced early on. The same group has been on 3 frames, there have been 2 rear cones replaced and a BB, plus tires, rims, cable, etc, but the basic group is still going.

You need to find a better shop that will actually order you things. Shimano UN-72 114mm is still made, though it might be the UN-74 by now.
