Octalink BB: Dura-Ace 7700 or Ultegra 6500
 

I acquired an octalink Ritchey Compact crank I'm going to install on an
older Cannondale. I have both a DA-7700 BB and an Ultegra-6500 BB.
DA s about 65 grams lighter but I just cruise. The DA-7700 isn't sealed
as nicely as the Ultegra. Has anyone found the DA-7700 needs more
maintenance and period cleaning and regreasing? Or any other thoughts
on this. Thanks Rick

No personal experience with DA, but others have noted that it needs a
*lot* of maintenance if you ride in wet conditions. Ultegra's last
~10-30K miles it seems... zero maintenance.

If weight's not a concern and you don't like tinkering or live in a
rainy area, use the Ultegra. The DA also requires a special tool.

Personally, I love my DA 7700 BBs, and on one bike I went two entire
seasons without an overhaul (maybe 10k miles). When I pulled it out
the bearing grease was clean. This is in So Cal with minimal wet
riding, so YMMV.

W/o doubt, The DA BB was poorly sealed, draggy, very diffucult to
adjust. Upgrading to the 6500 is best.

A friend of mine has an old 8 speed bike with a Shimano 600 group and never
changed the BB in 100.000 miles. He's a lightweight guy and makes more
rpm's than I do. I think that influences the longevity of a BB in a big
way.

the "fit and forget" solution is definitely ultegra, but the work of art
is the dura-ace. it needs more maintenance, much more accurate bb shell
prep, and doesn't last as long, but it's still a work of art. if you
get one, look inside the spindle by shining a flashlight in one end and
looking in the other - it's been internally machined so that the excess
material inside the "fat" part of the spindle has been removed - quite
extraordinary.

Fitted an Italian thread 7700 to my Colnago. Never did get the useless piece
of garbage to stay adjusted. Upgraded to 6500. No problems since......
