Problem with SRAM PF30 Bottom Bracket

<< < (2/2)

brmeyer135:
Heck, the thru-axles aren't necesarily a weight penalty if you spend some cash....Extralite
But, much like many like the ease of XT brakes....their weight penalty is overlooked also.

Surely, stiffness is improved just from more material 12mm vs 9 or 10mm...same with bb30
Now, is it any of us can register....seriously doubt it.

Exactly.  The engineer in me says "it's demonstrably stiffer! It's math!" and the rider in me says "yeah, but does it really make a difference?" Maybe to my wife who knows when her tire pressure is off by a PSI or so.   ;D

When it comes to BB, some companies make BSA bottom brackets that allow BB30 wider spindle (Rotor being one example). It is a solution gathering advantages from both systems nicely.
