Slight frame/fork wobble
If I hold my front brake on and rock my bike back and forth I get a bit of wobble between the forks and frame. If I hold the wheel up and try to rock the forks back and forward they feel pretty sturdy but there is a slight bit of movement.
I’m sure the space between the top of the stem and streerer is OK as ive tried different size spacers. I also think ive done it up correctly, ie preloaded the bearings before tightening stem bolts.
Anyone think of any solutions? Ive got a tapered headtube with 1 1/8th forks using a hope reducer race. Couldthis be the problem?

It’s most likely to be headset tension. Before tightening the stem bolts tighten the top cap bolt until the steering just starts to get stiff then back it off until it’s free and tighten the stem bolts.
Could be other things though. Are the fork slider bearings worn?Posted 4 years agoandylMember
take a look at the bottom of your stem cap and your star washer in your forks (or expanding plug if you have a Hope) and make sure that there is plenty of clearance between the two. Then make sure you have 3mm gap between the top of your stem and the top of your steerer when it’s all preloaded up – ie with the stem bolts loose preload the top cap to finger tight checking that all the bearings are seated correct and then remove and check.
If you need to use a spacer above the stem.Posted 4 years ago
Some good suggestions but I seem to be complying with them all and still have the problem.
Its a new headset,
Enough gap between top of steerer and top of stem,
Top cap tightened followed by stem
It is only noticeable when I rock the bike back and forth with the front brake on or I hear a slight clunk when I brake using just the front.
Anyone else with any solutions this is driving me mad.Posted 4 years agonick1962Member
Process of elimination.Posted 4 years ago
It’s not the brakes ,rotors,wheel bearings,quick release,wheel seated correctly in the dropouts,stem clamp?
When did it start and what changes had you made,if any?
If none then maybe fork bushings as already stated.
Not seen the Hope headset but I know with my reducer headset I had to push the ring down with my thumbs that sits next to the bearing race and make it all snug before tightening the top cap.
Good luck and maybe get someone else to check if they can feel where it’s coming from and if all else fails dismantle everything and put it back together again.
