Tight headset
So, this is weird issue. I just change my bearings of my headset. They are caged bearing. I tight the start nut normal, and I noticed a tightness sensation when moving the handlebar. When I ride also I can feel it.
I loose a little and still feel it. I cannot loose more else there will be a little play. I have never experienced something like this before. I can ride the bike but I can feel that tightness sensation too. What are the possible causes for this? |
The upper bearing cup is probably bottoming out on the top of the frame and needs shimming for clearance. But would need to see some photos to confirm what is going on there.

POints to ponder:
Did you replace bearing with the exact same model of retainer? Is is possible the bearings are in upside down? Did you pull the cups out of the frame in your service of the headset? If all else fails: Going to a loose bearing is an option as well. rusty |

And yet you obviously did something wrong.... Maybe time for a visit to the shop?

Just saying that apparently it worked OK before he messed with it.

I forgot to add, when I got the caged bearing, it was a little bend. I tried to get it correct but not fully. Both caged bearings. Not sure if this is the cause. I will switch to cartridge bearing next month. I will keep riding meanwhile. This sucks.

C'mon OP, you've been around for a few years. This is a mechanical question and should be in 'bicycle mechanics' not general discussion.

i've had these same symptoms on a couple bike builds over the years : for me it was the top lock nut was very slightly running out of threads before touching the top of the fork tube. i added a 1 - 2 mm spacer in the headset stack and it fixed those symptoms

I get the impression, though I am not completely sure, that this is a threaded headset ("tight the start nut") and not a threadless unit. I'm betting on the bent bearing cage. It also is possible that the bearing races are dented (you can see this visually) and that you have the so-called "indexed steering" as a result. This could happen because when you reassembled the headset things lined up differently than before you did the overhaul. Or maybe you had this issue before your maintenance but didn't realize it. I'm curious how you could install cartridge bearings in a threaded headset that was designed for loose/caged bearings.
For the sealed bearing, well, i will install new bearing cup which are coming with it. Already bought online. It will be here next month. I used sealed before, never got that issue. In fact, I have assembled forks many times o different bikes too and even with caged bearing I have never experienced that. |
Still got the old bearings? If so, pop the new bearings out of their cage, install them loose in the race (use grease to hold them in place) and add as many of the 'old' bearings as necessary to make up the remaining space in the race leaving room to add one more,(but don't). Headsets run smoother with loose balls as opposed to caged ones - much free-er to rock and roll as needed.
