Yesterday at the back end of my ride and fortunately on the way home, my freehub decided to not freewheel any more. it had been sounding rough for a few days but, when it went in to fixed mode it was a bit of a surprise.

I had the thing disassembled the day before and regreased everything that I could sse but I fear it may be irreparably damaged.

it has done 30000 km rain or shine so I think it might just pay to replace it as the spares cost more than a decent hub....

any views on what I need to do?

    sounds like freewheel is done. Have a look at prices of new ones or just buy some Obermayers

    then get the broken one, smash it with a hammer, set fire to it and lob it in next door's garden.

    my thoughts exactly. except perhaps i'll just get a hope hub and fit it in place of the dead dura ace hub, and get replacement spokes etc. maybe...

    any views on hope vs Dura ace vs whatever else is out there on the market place?

    Is it 11 speed? 'Cos then Campag is compatible with it.

    Shimano freehubs are completely enclosed, so there is not much service you can do. If it's done 30K, it owes you nothing. Just get a new freehub. The old one might be a bit of a pig to unscrew, as these things are torqued as if they were car engine components... maybe ask Sigma to do it. Being a titanium freehub, I suspect it won't be a cheap spare part

    How so? They don't even have the same mounting system... one slides on the axle and the other screws on the hub body

    the way I see it, is its a full hub replacement. I took the user serviceable section apart again yesterday and it looks as though its died. the non user parts were sounding very rough and its pretty clear it had seized....

    i'll replace with a hope or similar hub when I get paid. (this was the zipp wheel you rebuilt for me). as you say, its done its time!

    Remind the builder there are oval washers on the nipples. If you don't find anyone who wants to do it for less than a million in London, send it to the Midlands and I should be able to do it for a couple of pints of Purity Lawless :D

    the freehubs for Dura ace are seriously expensive, it's a pain they cant be serviced. Mind you if youve let the rest of it get completly trashed you probably wouldnt have dont the free hub in time either :)

    if the rim has 30k miles on it, is it really worth rebuilding with and expensive hub?

    check the rim please before paying £140 for a new freehub.

    they were serviced every quarter to the best of my limited ability. also because one part isn't user serviceable it was only a matter of time.... still when it gave out it was pretty spectacular....

    as for the rim, it is fine. both front and rear are sound. though yes I get what you and cycle clinic are saying. I don't brake much :D

    true, a definite conundrum. the 303's are very very strong wheels though.

    of interest, are there any mechanical properties I should look out for, I know of obvious patches of glazing or where the brake surface appears glazed (remember these rims predate any form of impregnated materiel into the build). I think i'll have another look at the rim and double check, just in case!

    Just check rim thickness against the front one, if you've got over 1 mm, then you are good... there are gauges to do so
