Who makes the best in terms of Durability and bearing Quality BB in ISIS under say 170 grams? Is their a Chris King or Phil Wood type of quality BB out their in ISIS?

I hear you. I just put a square taper Phil Wood on my bike. I'll bet they have an ISIS out one of these days. They won't put it out there before they know it's right though. It might take a while.

No-one

I don't think we will see a ISIS BB from either CK or PW. PW wanted the 48mm BB shell or something similar and CK just wont say anything.

There is the OS BB standard that Campag/Pinnarelo has been playing with, but I'm not sure there will be the industry acceptance of this.

The Outside bearing BBs apear to be the best solution for a aftermarket BB for an oversized BB axle- At least they all appear to be using a 22.2mm axle.

I think the best solution is an oversized BB like Cannondale, the new Pinarello etc., but it will take some time to have a standard for this

It will be very interesting to see if Tune's exceptional design comes to the surface...

...Their "Six-Pack" Hexagonal Taper BB design.

It is on the Giant Showbike, WW's 2nd lightest bike!

this has been in the works for quite some time... http://www.oversizebb.com/

does this mean your spada one has died in less than four months?
