Re: Bike Mechanics Impart Their Wisdom On Vorb

I've got a cane creek 40 headset on my cross bike. I noticed the forks wobbling and sticking a bit, so took it all to bits and found the bottom bearing was virtually seized. Replaced the bearing, put it all back together, but the play is still there. All tightened down as much as possible (I tightened the stem bolts last of course).

Question: Can the headset be stuffed even though the bearings are smooth? Where can the play be coming from?

Slightly shorter bearing causing the top cap to bottom out on the steerer before correct tension is reached?
Try adding another stem spacer as a test... 1mm is plenty to cause knocking.

Nah, but thanks for the suggestion. Plenty of gap between steerer and top cap filled with a spacer. It's a crabon steerer and so uses a funky metal thing inside it for the top cap to bolt into. I'm wondering if it has a really limited ability to pull everything tight as I do up the bolt.

Is there a gap where the top cover sits against the top cup/ headtube?

Are you using the correct crown race?

Did you adjust the headset compressor cap (funky wedge thing in the fork) correctly, its a 2 stage process, where you tighten the lower part into the fork steerer, and then finally tighten the top cap

Yes to all the above, except the last one. I was only tightening the top bolt, not doing two stages, so I guess the top cap is bringing the compressor to the cap then expanding it, rather than pulling everything together. I'll try the two stage approach next

Edit: sorted thanks. Found the 6mm key thing to do up the compression compressor after unwinding the 5mm topcap.

Might be a dumb moment of mine.

My mother has bought my late stepfathers up bike down. It's got a rear thru axle with a shimano skewer. I open it up to unscrew (as I would on my RS fork TA) but instead of the axle turning, just the latch bit comes off. Can't get the axle off at all to get the wheel back on.

any thoughts?

One of those nut things. I think mums neighbour torqued it on too tight with no wheel in. Will dig out the stand and sort it out tomorrow.

Sheared? Looks like a normal Shimano x12, but you know, broken.

Didn't get time to check if it was sheared, didn't appear so but guess these things never do!! Could make sense if it was done up too tightly with the wheel out and the frame has flexed up. Will have a look tonight.


Any ideas for getting it out??
