Ate up another DA BB. Next one's gonna be Ultegra

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Ate up another DA BB. Next one's gonna be Ultegra

Last year I chewed up the cones on my DA 7700 BB after less than a year of use. I chalked that up to my overtightening of the BB after the BB shell came unbonded in the frame. I threw another set of cones on, but those have now bit the dust too.

After asking around, the general consensus seems to be that the DA7700 BB is prone to going south unless it's perfectly adjusted and re-adjusted frequently. So I decided to replace it with a 6500 Ultegra.

So now I'm on the Scattante until the new BB gets here. Funny how I never had these problems with my old square taper DA BB.

*sigh* I feel for you man. check out my post on "sos! my chain snapped". Some of these new lightweight parts give people a lot of grief. I never had any problems with any of my bikes (I have 4) until I started racing and went for the lightweight dura-ace stuff. Ironically my best maintained bike is the one with all the problems.

Yeah, I saw your broken chain thread. I broke 2 or 3 Shimano chains before I started using SRAM on all my bikes (road and mtn). No problems since then.

P.S. Here's an interesting article about 10-sp chains.

Man, you have some bad bike mojo going.

I have about 3500 miles on my DA 7800 bb/crank and no worries. (of course I've got that sticky brifter thing going on, but that's another story).

Yeah, the external bearing ones are probably better. I have one of the finicky old Octalinks.

Not because I am such a smart fellow or anything.
I replaced my old 105 cranks with a set of 6500 Ultegra cranks and I asked about the 7700 BB.
I was told to steer clear of that one.I also found somewhere on the bike pro site that the 7700 isn't very good and that many people with the 7700 crank set end up with the 6500 BB for that reason.
