Author Topic: Is it right that the steering on a low-racer bike has a "notch" at dead centre?  (Read 234 times)

I have never noticed it before and I have had the bike for ages. I have always assumed that the headset bearing is standard and I can't see any reason why this should be a feature.  But being so central when it occurs when I move it from side to side when stationary, it feels that it COULD be normal.  Looking back, I did hit a fairly major pothole at speed about a month ago, which in turn caused an inner tube / tyre blowout and a long slide down a hill. Is it possible that this has smashed a ball bearing inside to cause this feel?

I have lost a bit of confidence in the handling and I don't know if that is psychological in that I THINK that it is not as it should be, or if this "notch" is actually causing a real instability ie my brain is not used to overcoming the slight resistance on a tiny movement from centre.

If it is a ball bearing issue, is the headset easy to replace on these things? (it is one of these https://mccraw.co.uk/2012/09/01/challenge-fujin-sl-review/ , adapted for long- distance light touring)


It's a ruined headset.  Kim will be along shortly to advise if it's a standard fitment.

Not sure about the Fujin, I don't *think* it's integrated, is it?

But yeah, agree that it's not supposed to have a notch, which is a normal function of headset wear.  I think recumbent headsets have a harder life in this respect than uprights, as they take more load.
Careful, Kim. Your sarcasm's showing...

The link ^ has  pics of a standard (not integrated) headset

It  will almost  certainly have cartridge bearings

If you can find the size these people are good for replacements

Double check how much pre-load is on the headset bearings.
I have had that "notched" feeling when I've tightened the headset by to much.
At slow speeds it start to feel like my trike is hunting for a line around a corner.
See if loosening the load on the bearings a fraction frees them up without adding any play.
I've had success doing that while on tour, I've probably got more leeway on a trike with twin headset but doing this let me wait till after I got home before fitting new headset bearings.
If you don't loose the notch before you get to much play in the headset then it's new bearing time anyway.

Thanks all, that is so helpful
