Okay somewhere in the middle lies the truth :). I just wrote RK Excel and this is what they said.
"We have postponed the sale of the “Pro-Series” sport bike wheels.
It had been brought to our attention that one of the drive carrier bolts had backed out of the carrier.
Which in turn had cause damage to the swing arm.
Being that we are unsure as to as to the cause of this incident. Either as a result of the manufacturer or of the customer possibly removing the bolt and not reinstalling it correctly. We feel that in the interest of consumer safety that we should halt the sale of the wheels until which time we came insure that the bolts are secured properly to insure the safety of the user.
After which time we sale of the wheels will resume." Gary L. Kies, RK / Excel America
So no "catastrophic loss" unless that guys swing arm was chromed (or would that be a catastrophic win? LOL). Anyway, my wheel had two different sprockets put on and off it at 40+ ftlbs of torque and those bolts didn't go anywhere.
1. That guy over torqued and/or stripped the nut on the way off bad enough to loosen a bolt from the carrier (probably in excess of 80 ftlbs to do that). Or actually removed it for some reason (again, not easy!).
2. One or two people turned ONE bolt SCRATCHING a swing arm into CATASTROPHIC FAILURE (not saying its you guys).
3. RK Excel can't afford the bad PR
right out of the gate and is either out or changing the attachment of the carrier bolts to be idiot proof.
Personally I would keep using them and maybe look now again like I do for clip ons, rear wheels, calipers, and chain guards... all of which I have had come loose or completely off while riding (the clip on was a undy stainer LOL).
