I'ld like to meet the Eyetalian Engineer(s) that sat at his computer and dreamed up that application of using a .015" thick wave washer to tame that thrust load. Deflecting a wave washer until one bit of steel or aluminum bangs into another is...child's play.
He(they) should be made to listen to that infernal damned ticking sound until they're insane enough that we never have to worry about his(their) next design.
And yes, "Over Torque" sucks from the very moronic name chosen for Campy's latest abortion method of attaching two sticks to and axle to the drawer full of proprietary tools required install and remove said sticks to the 15 pages of instructions and pictures and two videos needed to be watched so said proprietary tools are used properly on said sticks.
Alf, did you check out he new threaded locking collar now used to control preload/endplay?
What.
The.
Hell?

FWIW. Not that the folks in Vicenza care what 'I' think ...
But, based on my limited-and-superficial understanding of the O-T Crankset, I think the Campagnolo engineers have finally
jumped-the-shark with the Over Torque Crankset/BB design ...
The O-T Crankset might have been
acceptable if it had preceded the Ultra Torque & Power Torque Cranksets ...
By my reckoning, the O-T crank design follows what can only be described as a
pre-Tullio design philosophy which also harkens to
pre-IR (
as in "Industrial Revolution") thinking where simplicity is shunned in favor of the alternative ...
Oh sure, it's nice that there are apparently seals where an extra slathering of grease was supposed to be used with the Ultra Torque crank installation ... but, an excess of additional small parts can be (
is!) a nuisance, IMO ...
So, while Shimano's apparent philosophy of facilitating mass assembly on the production line unfortunately also means disposable components, I think that managers/owners of small bike shops would-or-should think twice before ponying up another $100+ for a proprietary tool which might be used 2x a year AND become obsolete before there was any hope of recouping the cost of the tool ...
Heck, EVEN Shimano ultimately realized that the proprietary headset wrench [
and, you needed TWO] for its fluted locknuts was not a good idea.
If I were a
race-or-"team"-or-any-type-of-neutral-support mechanic then I would suggest that the non-sponsored rider consider using a comparatively generic FSA-or-Shimano Crankset or older generation Campagnolo Crankset OR let the bike's BB go un-serviced at-or-during the event OR make him/her buy-and-bring the O-T installation/removal tool.
No matter (
to me, anyway) ...
There will probably be a
UT30 crank in 2015-or-2016 which will make the first (
and hopefully, last?) generation of O-T cranks "collectors" items (
not unlike the Delta brakes).
