First of all, hello to everyone, as this is my first post on a bike forum. I ride a Cannondale Supersix Evo (approx 2013 model, I think) which came with Shimano RS11 wheels. Whilst out riding a couple of days ago, I suddenly noticed no power when pedalling & discovered that my cassette was moving freely in both directions! Not good I realised! After removing the cassette I presume it is the freehub that needs replacing. However search though I may online I cannot find the exact replacement. I have also just spent £50 on a new cassette so I presumed that I would need an exact (10 speed) copy of freehub. I did have a go at trying to remove the freehub but my home mechanic skills (& probably limited tool kit) just weren't up to the task. I have contacted my local bike shop & they are understandably busy at the moment, but I will keep trying them. Any suggestions/help would be very much appreciated.

    Shouldn’t be hard to remove with a 10mm hex key. See guide here - https://si.shimano.com/pdfs/dm/DM-WH0002-11-ENG.pdf

    The freehub body in the link below should work.

    As above it should be easy enough to get yours off and inspect it first, have a look at the parktool guide for instructions. You might just need to clean it out and regrease the pawls?

    As above, sometimes the pawls get gummed up with accumulated muck and grease. Get the freehub off and give it a good clean and regrease. May well solve the problem.

    I've had them apart before to clean it out and put lighter grease in there (they freeze in winter sometimes, below about -5C).

    If I were you I'd get a replacement but hang on to the one you've got. It will probably be fixable as and when you feel brave enough.

    (Or do it now and prepare to feel extremely irritated at Shimano).

    Thanks very much everyone for the suggestions. I would like to have a go at sorting it myself so l'll check out the guides & have a go. Will let you know how I get on.

    Phew! Sorry for the delay in getting back to the forum. Basically I ordered new bearings & the freehub (from SJS, thanks again for that link) & then waited until I felt brave enough & the weather let up sufficiently for me to work on the bike (very rainy the last week or so!). Anyway, decided to have a go today & have just finished successfully replacing the bearings, grease & a brand new freehub. It wasn’t straightforward all the way but then in my experience jobs never are, but I did feel a sense of achievement once it was done & everything was working fine. Once again, thanks to everyone for their encouragement & advice.
