I wish I would have known about The Rogue Mechanic's website when I first encountered the Ultra-Torque 'tick'!
I was told the BB bearings were faulty...replaced.
I padded my pedals with tape to isolate cleat noise.
I replaced the cleats.
I replaced the pedals.
I tightened every fastener on the bike repeatedly.
I tore apart and greased the BB assembly parts several times.
I actually bought a new pair of shoes to try, thinking the click may have been coming from an internally crack sole plate!!!
Finally! In complete desperation to stop the infernal ticking noise I ordered a couple 1 mm and 2 mm bearing cup shims DESPITE my frame's BB shell being on the HIGH SIDE of the width tolerance and milled square to the bore axis and parallel within ±.002" as checked on my granite table!!!
It took a full TWO mm of spacer behind the left side outboard bearing cup to cure the noise.
My next bike took 1 mm of spacer to cure its ticking. That shell was right on the high limit for width.
Both of these bikes were built by pro mechanics at Colorado Cyclist and Competitive Cyclist and neither outfit had a freakin' clue as to why the cranks were knocking or how to cure it.
The Rogue Mechanic figured out Campy's idiotic up 'wave washer' (actually, a Belleville Washer is the correct nomenclature) design. He figured out what the problem was (excessive and uncontrolled travel endplay due to tolerance stackup and near zero preload under pedaling forces) and how to cure it (reducing side clearance in the BB assembly to levels that reduce side-to-side movement in the crank spindle assembly).
I figured it out, also. After an entire summer of listening to that damned noise and untold labor, time and expense. A pox on Campagnolo for introducing that insanely retarded design and releasing it to the public.
It's as screwed up as maydog's Truvativ GXP self-destructive cap bolts! [IMG]files.cyclingforums.comconfused.pngOpen ↗[/IMG]
And now we all get to use Campagnolo's new 'Over Torque' design. I have not worked on one yet, but the technical documentation indicates it's even MORE retarded and complicated design and involves the use of several new proprietary tools.
