Cassette or Hub Problem? Help?

Apologies if i don't use the correct terminology and stuff, not long been into mountain bikes.

Basically i've got a problem with my cassette or rear hub. As i was commuting to work this morning i found that when i turned my pedals it wasn't turning the rear wheel. It had been working but after a bit of a downhill i got ready to climb a hill and realised that i wasn't getting anywhere!

I've looked at the cassette and i remember that it only normally turns anti-clockwise as you look at it and it resists turning clockwise. Now it turns freely in both directions. Nothing looks loose and i didn't hear any kind or braking noises?

I've got a specialized hardrock sport 2007 with no upgrades.

Am i looking at a problem with my cassette or could it be the hub? What connects the cassette to the hub? Could it be a problem with that?

Sorry for sounding naive but didn't want to go running back to the bike shop yet if i could replace a part myself, if it was the cassette then i'd be happy to replace that but obviously a hub issue i would take to the bike shop.

My local bike shop is 16 miles away so don't want to go there needlessly.

    it will be the freebody that need replacing.

    tools needed chain whip,cassette tool and a 10mm allen key.

    have a read of parktools about feebodies.

    linky below.

  • That's great, thanks for getting back to me.
  • Further to my previous message, just been out to the garage sorting some stuff out and checked by bike whilst out there and it now seems ok? The cassette no longer turns clockwise like it did this morning? Has anyone heard of anything like this? To be honest to play it safe i think i will take it to my local bike shop as i've already booked it in but just seems a bit bizarre that it seems ok now?

    yes, happened to me. will still need a freewheel, coz itll happen again when your slamming on the pedals and youll go flying over handlebars :shock: dunno why like, hink the rachet will just sometimes catch

  • It has happened to me before and it was a cold winter night. I was told by LBS that this happens when the freewheel is dry and the mechanism freezes.

    When the temp rose my freewheel worked and I could pedal again.

    Since then I have always ensured I clean the parts and make sure I get them serviced.

    It is a very strange thing when it happens to you!!!

    I would not rush out to spend cash yet.... good luck

    It does sound like a frozen freehub, it's been bl**dy cold in the morning recently, couple that with when it happened, after going down hill (at speed). There were a couple of threads in here recently about it, p*ssing on it seemed to be the favoured technical response :D .
    It's easier to ask for forgiveness than for permission.

    I've bought a new bike....ouch - result
    Can I buy a new bike?...No - no result
