|Will a spline Dura Ace bottom bracket(7700) work with a spline Ultegra(6500) crankset? I read somewhere that you need Dura Ace for Dura Ace, But i'm not sure.|

|Either will work.
The 2001 DA BB's had adjustment and seal issues...more difficult to adjust well for novices, needed servicing after wet rides...but worked wonderfully when set up properly and maintained. Saved a smidge of weight over Ultegra.
I've been told that the 2002 DA double bottom bracket is now a sealed unit similar to Ultegra, though I've not seen one, yet. The 2002 DA triple is a sealed unit.
At any rate, the Ultegra BB is smooth, of first rate construction, largely idiot proof and very long lived. Why not just use it...

|Go the other way around if any... The Dura Ace BB is, indeed, a pain. If you like to continually adjust it, repack it, it's a great BB. It is light. You need the correct tool to adjust it as well, otherwise you'll totally f-up the soft aluminum lock rings, even then, you need to be careful.
I went with the Ultegra "install and forget". I ran Ultegra cranks then got a set of Dura-Ace... Cuz they were too purrtie to pass up. Still run the Ultegra BB...
No worries mate...

|if you have an english threaded bb, get the dura-ace track bottom bracket. it's a cartridge (sealed) and requires virtually no maintenance. it's spindle is the same length (109.5) and the splines are the same.|
|good idea... How is the weight compaired to Ultegra?||Geof|

|i rode it simply because of the fact that it was sealed. in the year that i had that bike, it never presented any problems and was very smooth. on my current road bike, i have full d/a and am running an ultegra bb. i seem to have a problem keeping ultegra bb's together. i'm on my 3rd in 15 months! if you have the $, get the d/a track.|

|Buy an Ultegra BB- it's exactly the same as a Dura-Ace track BB. Even the same price...|
|Got it for Christmas!||James|

|Yes it will work. |
Be warned that the DA BB is a real pain in the butt. All my bikes have Ultegra BB with DA cranks.
