Hi, got hold of a couple of wheels: deore hubs and mavic rimes (rear with 9 speed cassete) , wanted to give them a service and fit them to (7 speed) pub bike. Got a 7 speed casette and spacer.

Front wheel fine, fitted. rear wheel left side fine but right cone rough, pitted either side of bearing track, bearings dull and pittted and cup in similar shape to cone.

i'm guessing i need a new cone, bearings and cup (so freehub?), if i stick with 8/9 speed this wont mess thinds up, right?

then noticed the spokes, all nearest chainline are gouged and bent

so also need 7 new spokes and key...and then? replace one at a time while keeping the wheel true-is this difficult?

    Ask at your local bike shop and see if they have a spare cone to fit, the cone is softer than the cup and wears first you might be lucky and the cup wear is not too bad. Put in new ball bearings and lots of grease and it should be fine for a pub bike just regrease it more often than a new hub would need. If the drive side cup is totally shot a new Deore freehub is not too expensive and easy to fit only needs an 8mm allen key iirc.

    Replacing spokes is relatively easy, take one out and take it to the shop for comparison. Just do it one at a time like you said and get the rim running true before you start on the next. Double check you have the lacing right.

    I would get a new Deore hub and swap all the internals into your existing one, you get a new QR aswell

    You need to be replacing spokes as well so get a new complete hub and be done with.

    Just take off the "old" freewheel hub unit as a spare, good to have, and if any cones are not pitted (left one?) keep that as well, cones theoretically available as spares but seem like the holy grail. Oh and the axle too, these can snap!

    Pub bike - what's the point?

    Grease and re-fit - done.

    ok given the non-drive side of the hub is in very good condition and i'm not too confident about re-lacing the whole wheel, i think i'll buy a whole new hub,fit the freehub and drive side cone and bearings, and replace the 9 damaged spokes, keeping the leftover bits to build up another wheel at some point in the future.

    thanks for the advice guys. :)

    chunkers, its my commuter as well so i like it to be in good shape and its a bit of a project bike for me to learn stuff on, i just dont want to spend much £ on it. :wink:

    i am overfond of it though :oops:

    That's cool - you do need something reliable for that.

    Yeah the new hub option does sound best - you can fit at a later date when there's time or you feel you now have the skills and just do the fix for now.

    Make sure when you change the spokes over you get them in the correct under over pattern. Do one at a time and try and match it to the correct tension one by one as well.
