Adam F said:Hmm OK cheers. I think I need to look at an exploded diagram or
something, I'm clearly not up to speed on the internals of a hub - just
don't understand why changing the fastening mechanism (assuming the
axle's the same diameter) necessitates a change of bearings (would it be
impossible on a sealed bearing unit?)
Basically you've got a threaded rod (the axle) that ties everything
together. On that are the cones, which are nuts with a ball bearing race,
and then the locknuts outside that. Between the cones sits the main body
of the hub, with the bearings between the hub and the cones. In the case
of a QR axle the axle itself is hollow and has the QR through the middle.
I'm sure there's a piccie on either parktools.com or sheldonbrown.com ,
along with more detailed instructions for adjusting cones.
Anyway, unless the bike's using cartridge bearings which just snap in,
those bearings are loose balls. Putting in a new axle means you need to
swap them all, so it's a bit fiddly, and you need to get the tension on the
cones just right. It's not that hard if you've done it before, but bank on
an hour or so for the first time while you tighten/loosen the cones until
you get them rolling nicely with no wobble.
