[Closed] Hope Cassette!

Green though.

Looks interesting. Wouldn't want one though! Does solve the issue of cassettes eating their way into those alloy freehb bodies.

hasn't something similar been done by shimano 20 years ago? it was called a freewheel sprocket :roll:. Plus will it shift as well as shimano? doubt it.

I'd like a blue one as an ornament 🙂

How muuuch!!?? 😯

[i]Hope cassette works out 20g lighter than with a freehub and SRAM's top-end XX sprockets fitted.[/i]

Its not just 20g, but 20g lighter than an XX setup.

Might be useful as a racing 'spare', if you've already one of more ( 😉 Hope hubs already - and at XTR/XX prices - so competitive.

Yeah, the 22 and 32 tooth aluminium TA rings I had fell apart with comedy quickness, except for the fact they took a chain and a weekend's riding with them...

I'd have thought you'd be the first to argue that these aren't aimed at normal riders though Dougal, you could probably get a season or two of racing out of that cassette if you only used it on race day?

It's an interesting concept and I'm glad people are trying these things.

doubt it.

This actually looks more interesting

. Expected to hit shops in early 2011, the new cassette will sell for around £150.

I like Hope stuff but that chain device is fugly...

Looks better than the crappy MRP equivalent.

When the XX cassette is £250 looks like it's a bargain.

Apart from the XX being machined steel and (probably) lasting longer.

Suppose it depends how long the Hope one does actually last.

I get through normal cassettes probably twice a year if I change my chain (and chainring if need be) three of four times.

two XX's =£500. Suppose the Hope lasts half that. annual cost of £600.

If you like bling, like weight saving, and can afford to spend £250 on a XX cassette how much does £100 mean really?

When the XX cassette is £250 looks like it's a bargain.

£306 at retail, and mine's worn out after a season, just as XTR would be. I think that looks really interesting.

Edit: although any hub that's 20g lighter than a Pro 2 obviously still weighs less. Also... I wonder if it's SRAM or Shimano spacing, as if we believe the hype they're not interchangeable.

Surely aluminium is fone for the big rings (say 25t upwards) as it lasts fine in chainrings which get a lot more use?

Maybe 3x aluminium rings, 4x Ti in the middle (light and hard), 3x steel (hard and cheep) would make a good cassette?

I'm still not entirely convinced but irrespective, it's good to see Hope coming up with something different. I wonder if they'll sell the gold/steel sprockets separately - that'd be cool...

Just another thought but hasn't Shimano's Hyperglide patent just expired which would mean that Hope could simply copy/use the same design...

EDIT - hmmm... seems that it expired a while ago actually.

Aye, and has been copied by folk like Recon for their full ti cassette.

Do the steel sprockets not just bolt onto the alu ones, so even if they did sell them aftermarket they wouldn't work with anything else, there's no splines in there.

KCNC do something similar for their cassette, they last about 30 seconds!

so even if they did sell them aftermarket they wouldn't work with anything else, there's no splines in there.

😳 ahem... yes, I didn't really think that through did I 😳

From the other post:

What about the SRAM XX cassette @ £200 +

And a hope Pro II freehub body is say £60

So combinfed that £90 for the cassette and £60 freehub body - dont think thats bad - However when the casette is worn then presumably you chuck the lot?

Buth then how would you change the bearings? I presume you can detach the integrated freehub part and replace the bearings and so I guess get an aftermarket sprocket set - also the lower 5 rings are replaceable - so probably would be fairly cheap after the initial outlay as its the first 3-4 sprockets that wear on my bikes !!

But the alu sprockets would wear relatively quickly too (quicker than a normal cassette certainly), so I'd expect them to wear quite quickly. They'll certainly look tatty quite quickly.

I think you are missing some of the point. The cassette is a 9-34, giving you a better range as well.

No use at all but couldn't you swap the springs and pawls around in the back of that and have a bike that freewheels forwards and drives backwards? Or build a bike with the drive on the other side?

Also on the bikeradar front page is the 250GBP SRAM 9-speed cassette - makes the Hope look like good value.

Question, though, does the integrated freehub have as many pawls and engage as quickly as a regular freehub?

Like Dougal says, anyone who cares about low weight won't want to run hope hubs. They're 100g more than a set of XTR hubs, and the idea of alloy cassettes lasting 6 minutes and resulting of a weight of 80g more than the equivalently priced XTR set up just makes it sound silly.

[i]Question, though, does the integrated freehub have as many pawls and engage as quickly as a regular freehub?[/i]

You would think so, as it looks just like a cassette mounted on a standard Hope freehub.

Me wanty so baddy, but the limit for a cassette would have to be £80 for a coloured one that would last a while for me I'm afraid.

Would these fit Mavic Dee's wheels then?

Well, they're closer to 50g heavier than a set of centerlock XTR, but then centerlock XTR will need another 60g of centerlock adapters or heavier rotors, and this is comparing 160mm XTR to normal Hope floating rotors, never mind Ashima etc. DT centerlock adapters are 30g per end.

There are lighter hubs, but they're pretty weenie, XTR certainly isn't an example of one of them.

The new cassettes aren't mid ranged bits, I'm surpised everyone wants sub XTR/XX weight for SLX cost.

Would these fit Mavic Dee's wheels then?

No, only hope hubs. The cassette has the innards added straight to it and the whole lot pushes onto the hub like a freehub body would on a normal hope hub. It has no lockring, that's how it can have a 9t bottom sprocket.

 

Are we gonna see a set on your bike at Plymouth then BS?

9-34 is interesting way to go, I'd have thought there would be efficiency losses on a 9t, and that it'd wear rather rapidly.

cool- that green cassette will go with my apple green bike

Maybe, actually not because only 10 speed have been prototyped and are well into testing at mo and i'm still on 9 speed.
Apparently the 9t runs good and is made from steel with ti nitride coating, there will also be 10 and 11t options.

The idea is to be able to use a single ring with a 9-34 cassette for race set ups.

I suspect the green will be for the demo stuff only and there will be other colours for retail.
