I think this and the XTR M950 BB are the best ever. The catch is they must be perfectly adjusted - a lost art in today's bolt-on cartridge world, but well worth it. And yes, a bad adjustment will cause excessive bearing wear. I've logged thousands of mile without pitting or the need of frequent overhauls.
Product Used For: 2 or More Years
Product Strengths:Stiff with both ball bearings and needle bearings to handle lateral and and vertical loads.
Product Weaknesses:Requires a good mechanic to adjust it properly.
My Bike:Aluminum road frame and a steel single-speed hardtail. I also use the M950 on my geared MTBs.

BB is a pretty nondescript part, until there's a problem. I have bikes 20-30 years old, with virtually the original bottom brackets, and no noticable problems. Dura Ace BB gets replaced 2-4 times/ year, and I'm fairly easy on parts.
Product Used For: 2 or More Years
Product Strengths:Lightweight, the Ultegra BB probably is the same, but weighs more. Fairly easy to install.
Product Weaknesses:Noisy, If not overhauled frequently (at least every 2000 mi., 1000mi. is a better idea. Make sure the crank arms are parallel, and tightened to maufacturers' spec.
My Bike:Titanium roadbike, full Dura Ace kit, Velomax Ascent wheels
