I agree. I put the new 105 external bearing cranks on my tri bike rather than spending money on more expensive ones. Given that most tri's are relatively flat and there is no need to sprint I couldn't justify spending money on stiffer, lighter cranks. Stiff, light cranks have an advantage where weight is very important and where you are really putting a lot of stress on the cranks and don't want any give - like riding a hill or sprinting.
