Does anyone know what the differences are between the Shimano Dura-Ace BB-7710 'Track' and the 'Road' BB-7700?
Shimano knows. The tech docs are at Shimano.com...
Don't be @seafish :)

http://si.shimano.com/pdfs/ev/EV-BB-7710-1786B.pdf7700 is a thing of beauty and a joy forever, as long as you can find the parts, since it is rebuildable down to the level of replacing the ball bearing cones. 7710 is just a nicely made full cartridge BB, if something wears out you throw the whole thing away. I haven't cut one open, but if I did I'd be surprised to find anything other than the usual two ball bearings.

I purchased a bb-7700 'without seals' and a 7710 has turned up.
