Ultegra 10 spd cassette lockring

Does the Ultegra 10 spd cassette lockring not make that clicking sound when you tighten it, like the 105 does (and other Shimano cassettes I've encountered)? When I tighten the ultegra one, it is smooth. The only reason I ask is since the lockring and cassette came loose during a ride. Although I've since tightened the hell out of it, I wonder if it might come loose again because it doesn't have the clicking teeth others do. Perhaps a manufacturer's defect?

I don't remember my 105 cassette making the clicking sound when the lockring was locked into place. But maybe I didn't hear it because I was doing this job for the first time.

This should happen. The clicking noise.

My Ultegra 10 spd lockring "clicked" last night as I torqued it down.

Make sure you're tightening the lockring to specification. The installation torque is often marked on the lockring, and usually around 30 ft-lb.

OK, we need all the facts. WHAT HUB are you putting this cassette on. Some require a spacer under the cassette. You may not be getting it tightened enough so that it will click.

I don't hear clicking with my Ultegra cassette's locking ring. Instead, I can feel it slipping past what feels like detents as I tighten it down.

I don't know what you're doing, but if you can't feel it slipping the detents (or whatever it is that causes that feeling) then it's not tightening properly. This could be caused by the width of the cassette, including spacers, is too long. If there are extra spacers behind the three cog carrier, you could try removing at least one, but leaving a minimum of one.

Also, if you are switching to an 11T cog, you need a lockring sized correctly for that cog. In other words, a lockring off of a 12T Shimano cassette will not work properly with an 11T Shimano cassette. The opposite -may- not be true, but it's probably best to use the appropriate lockring for the configuration of the cassette being used.

Just the opposite actually. Leaving out a spacer will cause the lockring to not click as the wave washer will not be pressed up tightly against the serrated lockring as it's torqued down. Too many spacers would cause very little thread engagement as there's not much to begin with. An Ultegra 10 cassette should have a ~1mm spacer (I don't remember the exact thickness) between it and the freehub, assuming a standard freehub. If you have Mavic hubs, they may take a 1.8mm spacer in addition to any cassette spacers.

Right. I didn't try to cover when the cassette's aggregate length is too short.

My American Classic hub has two spacers behind it or the cassette is too short.

Yes, it is a Mavic hub, and it is using both the spacer provided with the hub and the spacer provided with the cassette. What is interesting is that I have two of these Mavic wheelsets that are identical. To both I installed a Shimano 10 speed cassette with the same number and width of spacers. On the one with the 105 10 speed cassette, the lockring made the loud clicking sounds as a wrenched down on it, however with the ultegra 10 speed, it did not, and that is what made me realize that that may have been the reason why the cassette came loose on a ride.
