|Can you use Ultegra cranks with a Dura Ace BB? I thought I was told you can't, but can you?|

|Sure you can, if both are splined and proper widths. But I wouldn't run the Duraace BB, its just a bit lighter than the ultegra, more expensive and unsealed. I've never seen one last more than 2yrs of moderate racing/training. Most pro teams use Ultegra BB's for their easy setup/removal too.|

|... just installed one Ultegra crank to a DA BB (spined) and will be doing it on another bike tomorrow.
True that the DA BB is only marginally lighter than Ultegra, and is a bit more tempermental (though again, only marginally so)... but mileage will vary according to use. I had two on hand so I'm slappin' 'em in.
To it's credit... and I know this may seem a stretch to some... the DA is servicable...
Be the bike.

|A Dura-Ace track BB is .5 mm narrower than an ultegra and is completely sealed. It also has two rows of bearings on the drive side versus one on an Ultegra. The non-drive lockring is also steel, so there's less chance of stripping it when removal becomes necessary. It's a cartridge, so it pops in just like Ultegra. The only drawback is the fact that it only comes in english threading. I've ridden them in this configuration for about three years and never had a problem. They cost about $10 less than the regular D/A bb.|
