Hello

My cassette is stuck and I dont know how to get it off.

The lockring is off but the cassette no longer slides off the hub body...

A friend of mine thinks it may have 'dug' itself into the grooves from going up hills and that, so i tried knocking it back with a hammer to unwedge it but to no luck. I have also put a load of gt85 on it but that hasnt cured it either

Does anyone have any ideas?

The hub is a hope 2 and the cassette a shimano deore.

I guess I will have to take it to the LBS...

Are hope2 hubs 'soft'? does that happen?

Is the hub knackered?
Will the LBS be able to cure all??

    yes the cassette has cut into the body. XT and above cassettes for Hope alloy bodies.

    you will need to knock each ring against rotation until it disengages its self.

    will have done something like this.

    nice...

    thanks for that...

    is that the hub knackered then or will it be fine?

    depends on how far cut it is, but normally a quick file will generally make it usable.

    Hope do do steel bodies as well as alloy ones.

  • lol... knew it would be a hope hub before opening the thread.

    what cassette you using and was it standard on the bike?

    It's fine, file the burrs down to make the cassette easier to put back on.

    no, i put the cassette on about 6 months ago I guess, actually make that three cos I bought the wheels just after xmas...

    the cassette is a deore, I cant get the thing off, have tried all sorts now, think im gonna take it to the LBS and see what they can do.

    trying to put a new transmission on for summer and lok what gremlins come out of the closet!

    This is exactly the reason why Hope say XT and above on the alu freehub body. Hope do produce a steel freehub body if you need a new one and want to avoid the problem in the future.

    What do you think the LBS can do that you can't?

    A Chainwhip can be a good way to pull the gears loose from the freehub, pulling one gear against another if you have the usual 2 seperate outers.

    Two chain whips and and try to work the smaller rings off one by one

    oops.

    The freehub will be nicely chewed up.... as mentioned above, Hope freehub bodies are alu so need a cassette on a spider. ie XT or above.

    And you'll still get it happening on the smaller sprockets then. It's the price you pay with aluminium freehub bodies, but unless it's truly horrendous it is slightly inconvenient cosmetic damage.

    and slightly misaligned shift ramps and teeth..

    Or a loose cassette.

    Hope know that their freehub bodies are made of cheese. They mark and score even with a cassette on a carrier.

    The reason they don't sell them with the steel freehub body is becasue if would make it heavier than xt.... which is miles cheaper already.

    IMO, the only reason to buy a hope hub is for the colour...

    Hope freehub bodies are no worse than any other alu freehub body, it was just that Pro 2s brought alu freehub bodies to the masses. I've been filing freehub bodies on King, DT Swiss and Tune hubs for years!

    You should work for Shimano, we're talking what, maybe 3 degrees of misalignment? I doth my cap to anyone who notices a deterioration in shift because of that :-)

    I have always found the problem to be cosmetic.

    A sharp tap with a wrench always (for me) disengaged all the rings in one go.

    Make sure you do the lockring up very tight next time, I am thinking loose lockrings are part of the problem.

    Deore cassettes are crap, XT are amazing.

    A good middle ground is the new SLX which also has an AL spider.

    So slx or XT and a TIGHT lockring will fix this.
    Why would I care about 150g of bike weight, I just ate 400g of cookies while reading this?
  • slx casette isn't all on a carrier
  • SRAM 990 all the way!
    I've got them on both of my Hope Pro 2s and never had issues.

    When I bought my Blood direct from Orange, the first thing I did was replace the deore cassette they'd fitted before it did any damage!

    Neither is XT :? In fact, what is?

    Hope claim that it's only cosmetic. You can draw your own conclusions about how massive a lie that is ;)

    I am a pretty big guy who has managed to put enough torque in to shatter the pawls of over 5 hubs. Not once have I ever had trouble getting the cassette off an alloy carrier (that wasn't fixed by a sharp tap to release it).
    Also when I have the lock ring done up tight the marks are normally sub 1mm.
    When the lockring was not tight enough the marks are MUCH deeper, but still released with a sharp tap.

    I would side with Hope and say cosmetic.

    Yeah, but. You're a massive bear, on a tiny tricycle. You can decapitate a human with one swipe of your claw. What you can and can't do has no bearing on mere humans.

    But other people have, so.

    SLX and XT cassettes here, on a 3 sets of Hope Hoops so far. I just stick a wrench between the spokes and knock it off gently with a mallet. Move around and do it in a dozen or so places and it eventually just hops off. Can't say I've tried it with a deore cassette though :(

    Sure it's not recommended but I've never broken the cassette or hub :?

    Surprised anyone could use the maintenance reasoning for Hope hubs being worse than XT, seems a bit tenuous. It's been purely cosmetic from my experience and I've spent drastically less time fixing Hope hubs (once you have the proper tools) than I had faffing around with XT for the single year or so I rode them.

    I don't care how many expensive boutique hub makers have aluminium freehubs, it just strikes me as the completely wrong material for the job :?

    Why? They last for years without ever being an issue.

    Surely by the same argument you don't understand why XT/XTR cassettes exists at all? They just wear down fast, deore would last longer. 70g lighter wheelsets, the only inconvenience being taking the cassette off takes 5 mins? I'm in.

    No, I mean as an engineering princible. It's a spline interface, so it makes sense to make it from something tough.
  • toasty

    Maybe :)

    The forces should be spread out over the whole surface area of the splines, I guess it's just down to whether those forces are too big or not. 15-16 stone here and breaker of a few wheels so it should be a fair test, I do mash up the freehub bodies I must admit, it's always just been fine shoving another cassette on.

    What's your take on the Hope 1 piece cassette freewheel thing just out of curiosity?

    Is it American Classic that have the steel inserts for their alloy hubs? Nice solution that.

    I haven't seen how it's done yet, but it seems like an interesting idea. If anything, it will allow us to get smaller sprockets on the back.

    Just a thought, but wouldn't giving the freehub a TiNi coating eliminate this? I'm not sure though, since the underlying metal would still be aluminium.

    My mates new commuter has an intergrated freewheel and sprocket:

    :wink:

    The Hope set up is certainly an interesting development - I think we are going to see more and more of inhouse development from companies that will break current 'standards' (after all, the freehub standard is pretty ancient now) to save weight and improve performance. Maybe they will create new standards in the process.

    That said, Shimano have the Capreo system:

    SANY3267capreo.jpg

    This is a commuting groupset, but the freehub body here allows a 9t cog. 9t could feature a lot in the future, especially for those not wanting to lose the big ring, or those who want even smaller chainrings.

    A lot of the Hope weight savings appear to come from aluminium cogs (5 of them). Historically, alu cassette cogs wear very quickly.
