    Bottom bracket: 5500 (105) vs 6500 (Ult)?

    My 6500 is nearing its end.....almost 9,000mi. Was about to just replace it with the same, but noticed the 5500 for 1/2 the price ($50 vs $25). Can anyone comment on any differences between the two? Would you expect less life out of the 105 piece? Either one would be mated to FC6500 (Ult) cranks. Thanks in advance.

    Buy 2 5500s, toss one in your toolbox. Very little weight difference, same performance.

    The 6500 is sort of legendary, I can personally atttest to the fact that these things last forever. That said, I've had good luck with cheaper no-name brackets. If you plan to use the bike for touring, or if your rely on your bike to get you to work in the morning, I'd go with the 6500. Then again, bottom brackets usually don't fail; they just get progressively grittier. If it breaks down(it probably won't for a while), you could just buy a new one and still have only spent $50. You would have to install it, which is a chore... So, in conclusion, I don't know. Do whatever.

    Is your current BB showing signs of wear? Don't replace it just because it has 9,000 miles.

    As for which one to get, if it were me, I would get the $25 one. I think it is a much better value.

    Agreed. The 5500 is a fine BB, with a seriously minor weight penalty. Yeah, the bearings in the 6500 MIGHT be a little better and the spindle has a nicer finish, but that's about it.

    Yes, it definitely is getting "gritty" as one poster described....and was confirmed by a mechanic friend of mine. I have the bike stripped down for the semi-annual cleaning, so I figured I might as well be more pro-active with this than I was with my headset bearings (Integrated headset: outer race STUCK [pics]). I went ahead and got the 5500, thanks for the help everyone.
