I have been on profile-esque cranks for years and hate how difficult it is to take the cranks apart. But its not the end of the world as it normally only has to be done maybe once a year to change b/b or sprocket.
The system is not perfect but is developed and tested to work, so why spend money on it when you can just start selling something with a gimmick without much R&D and make a big buck?
Props for eclat and G to try and develop the crank market.
I think Eclat might be onto something with their new 48s/ wedge system, even though Profile did it before them on their Column Race cranks, It'll definitely make for easier installation and removal me thinks.
They work slightly different from the Elite cranks, with a bullet looking thing that is threaded and goes in the thru the other side of the spindle that the bolt threads in to, rather than having a taper on the head of the bolt itself.
They do simplify the actual sliding on and off of the arm, it just slides right off, but you need a long 8mm to hold the bullet wedge in place during tightening and loosening. They way I see it, its kind of a pain in the ass and I'd rather just install and uninstall my cranks the old fashioned way, but then again, I have never had a 48 spline crank wobble in such a way that I couldnt stop it. Seriously, the profile wobble thing is blown pretty far out of proportion on this website in my experience.
