Shimano Ultegra hubs give me the shimmies

Shimano Ultegra hubs, not so easy to adjust.


If Campagnolo made one product well, it had to be their Nuovo Record hubs. Mine are still going strong after 40 years of hard use.

What I like most about the hubs is their ability to be adjusted precisely with relative ease using hub wrenches.

I’m old-fashioned when it comes to hubs. I prefer unsealed bearings, although if I had it to do over again, I’d probably cave and go with sealed hubs, just for their convenience.

During maintenance, after installing new bearings and adding grease, there’s the final step of adjusting the bearing race. It’s an acquired skill, but once you’ve got it down, it’s easy.

The key is to tighten it such that the bearings don’t have too much play inside the hub, but not so tight that the bearings are binding.

Test for looseness: After installing the wheel and locking the quick release, try to wiggle the rim side to side. If there’s any play, it’s too loose.

Test for tightness: Spin the wheel and see if the hub turns freely for a fairly long time before coming to a stop. It should turn for quite a few revolutions before stopping.

Ideally, the wheel will rock back and forth at the valve stem before stopping, but that’s difficult to achieve. Consider yourself the bike repair whisperer.

The problem I have with my Ultegra hubs is that they’re hard to adjust. They don’t give me the same tactile feedback I got from the Campagnolo hubs during adjustment.

I recently serviced the Ultegra hubs (for about the fifth time), but during descents I noticed squirrely steering. The bike seemed to wander.

Sure enough, the hubs were a bit loose. I could rock the rim back and forth. It’s not much, but it doesn’t take much to notice wheel wobble. I needed lots of trial and error to get a good adjustment.
