Been backing off from external BB cranksets for a while now, but I'm sure many STWers have been using for a significant time now.
One of the great praises of the external BB design is their "stifness". That's their only one isn't it? Seeing as the BBs don't seem to last that long and there is no significant weight loss over the older designs.
My question then is - even if the BB is stiffer - once mounted in a frame that flexes under rider pedal input - is the benefit of a stiffer BB really there at all? is there any benefit?
I'm just wondering if the external BB design fixing something that was never really a broke (excepting ISIS).
