I have a Chris King front hub qr version and the bearings seem to have play in them.
As i dont know a great deal about them can anyone tell me if it is possible to tighten then up or do i need a new set of bearings.
If i do need new bearings are they easy to fit or is it a bike shop job.
Thanks
No you don't need new bearings. Remove the wheel from the bike, stick a 5mm allen key in each end of the axle and undo the end cap. You may have to give it a tweak as it's sometimes got threadlock on it. You then need to tighten "slightly" the bearing cap with the little knurled holes in it. Then re-assemble it and stick it back on your bike. You need to do this every now and again with King hubs.
Do i need a special tool to tighten the bearing cap with the little knurled holes in.
Thanks
No you dont need the tool, you can normally do it by hand, or put a small allen key in a hole and tighten it by pushing it clockwise, the tool is easier tho.

...If it's an older hub. The later models have an easier way. It's normal for these hubs to need a bit of tightening a few times when they're new.
It's all in here:
Some CK hubs use a different adjustment method, I know mine do.
You just have to loosen the pinch bolt, nip up the adjuster and tighten the pinch bolt again. [img]
