    Strengths:    Probably last a lifetime on my tandem

    Weaknesses:    Still drag a lot although put both bbs though many hours of drill rotation.

    Bottom Line:   
    Please help me. Should I buy new ones, doen't matter if I have to buy Dura Ace type. Price is no problem. Thank you !!!
    Or is there an equivalent but without any drag.

    Strengths:    Smooth and free, no perceptible drag. Long life.

    Weaknesses:    none

    Bottom Line:   
    Over a 10 year span I have put 54,000 miles on this bottom bracket and am starting to get a clicking concurrent with each pedal stroke, so it looks like it is time to replace the BB. I weigh 160 lbs and am 73 years old, so perhaps I have not put serious stress on the BB. I do pedal up 15% grades several times a year, though.

    Similar Products Used:   In my garage also are Litespeed Solarno, Mercier. None of these bottom brackets spin as freely as my Shimano 6500. (I do not know the brands of the bottom brackets for these bikes.)

    Bike Setup:   Litespeed Veneto 2003 with Shimano Ultegra components.

    Strengths:    Strong

    Weaknesses:    huge rolling resistance

    Bottom Line:   
    Shimano bottom brackets are terrible! The ultegra SL bottom bracket and durace BB are the same BB. Pull the bearings out and compare the rolling resistance to a ceramic BB.

    Strengths:    Not one problem what so ever.
    Did its job even when l weighed 260 lbs.

    Weaknesses:    Compared to newer ultegra external bearing bottom bracket it felt neither as stiff or smooth.
    Apparently some people have a bad track record with these but after my experience
    l dint see why.

    Bottom Line:   
    l have used this bottom bracket with italian thread for about nine years.
    How good was it? Never really notices it there during the hole time.
    The bike was ridden down many dirt roads but not though much rain and it didnt need to be replaced during that hole period and is now in storage should l build another italian bottom bracket bike.

    Strengths:    Mainenence free. Inexpensive. Good alternative to Dura Ace model.

    Weaknesses:    Not as durable as some may say.

    Bottom Line:   
    I bought this bottom bracket for use with my otherwise all Dura Ace 9 speed group. I was warned away from the Dura Ace Octalink bottom bracket by reports of poor durability in wet conditions. The Ultegra BB lasted about 5,000 miles before seizing up. I replaced it with same and so far so good after another 5,000 miles. Time will tell if these are really as bulletproof as some say. I bought spares just in case. They were cheap enough.
