Is there anything out there lighter than D/A 7800 (739/740 gms) that is still the outboard bearing setup? I don't want to mess with that setup as I've heard that it compromises the driveline alignment of the outboard setup.

If there's anything lighter, what is it and how much does it cost? Has Stronglight come out with any outboard setup yet? :?:

THM, lighter and stiffer with out board.

The new stronglight and time, though they have the integrated spindle, the bearings will still remain inside of the shell.

Though changing to a non-outboard style bb, will not effect the chainline enough to hurt shifting or have any negative impact(it will usually improve it). It will also reduce the Q-factor, which is a good thing for most riders.

Madcow,

You find the Clavicula crank stiffer than the 7800?

So when do you think you'll see one of these lighter, stiffer Claviculas--in a 175mm compact flavor, thank you--in Ralph's Shack?
