Bottom bracket for Ultegra
 

I have an Ultegra 6700 group on a Pinarello ROKH and was wondering if anyone had some suggestions for a new bottom bracket? I ride about 200-250 miles a week and am approaching a point where I need a sturdier bottom bracket. I was thinking about a ceramic Chris King. Any other suggestions? Links please if you don't don't mind, any suggestions on a good place to buy it aside from eBay would also be appreciated?

Either DA or Ultegra BB. Before you ante up for a CK BB, do some math to see how many DA BB's you can buy.
Shimano makes great BB's for the $$ just like they make great cranks.

Sturdier bottom bracket ? Explain

Could be bike shop upselling at work :P But the explanation by my mention of "sturdier" -- I stopped by the shop to get my derailleur hanger straightened out and was told I should look into investing in a better bottom bracket with the mileage I've been putting on my bike. Either way, a DA BB does seem pretty cheap.

And it's not really any better than a 105 bottom bracket. Or an Ultegra.

Yes please......explain. All Shimano outboard BB's are created usual and are sturdy enough for 99% of the TdF field.

the 6700 BB is pretty stout, no matter how many miles you ride. Someone is pulling your leg.

Is it that your so powerful that the new one died after 200 miles? Or is it something else?
