The Most Handsome Chainset

I think you need to catch up a bit :-)

That's a road crank, Campag still use square taper on their track cranks, no?

I use square taper and don't notice any flex. What is actually going to flex, can't see the axle bending?

Maybe I am just not as fat as you :-)

Outboard bearing BB's flex shit loads less than traditional BB's, where the flex is I don't know because I'm no expert but you can feel it with in seconds of pedalling.
