Thanks for your input everyone. Just in case it isn't just something "typical and common", I checked out the bent skewer hypothesis this evening and found it to be straight as can be. I aligned the skewer with a machined straightedge and spun it carefully to find no imperfection. I also checked for any wobble of the cassette; that, too, appears to be sound. But thanks for the ideas, 55-11.
Tmax1, I believe there are DTSwiss-made Bontragers, but not all of their hubs. I have the link with this info, but left it at work. I can post it tomorrow.
Now what about this...I remounted the rear wheel and set the chain on the highest gear (smallest cog). I lifted the bike by its saddle and cranked on the pedals to get the rear wheel spinning at high speed. The loud/quiet cycle of the ratcheting volume still remains. However, I noticed something else that wasn't apparent at slower wheel speeds or while I was coasting on the bike...there seems to be a slight weight imbalance of the wheel or tire that causes a slight up and down wobble of the bike. Again, I don't feel this when I'm riding it. The rear tire is tubeless and all I've done to it since the bike arrived in the box last week was pump it up. The wheel is true and, by sight, the tire is properly mounted (I don't see it wobble as I spin the rear wheel).
Does this help our investigation at all? Again, I appreciate everyone's input. Any news with your Race Lite's, CaptDon?
