My steering started to get all notchy, somtimes stiffening up as I turn. A few rotations of the bars seems to free up the stiffness.
Its not the headset adjustment.
I took it to a good bike shop, and the mechanic did an eyeball measure of the forks. He thinks that the forks are bent to one side through some inpact damage. The resultant sideways stress on the headset is causing the bearing to bind.
He said he had done that to some hard-ridden commuter bikes, they just wear out after a few years, one curb or pot-hole too many.
The forks can be bent back (cold-set) but its not worth the work, so he said keep riding it until it feels unsafe, then get another bike.
Has anyone else ever had such a problem ?
