I bought a 9-speed cassette online, and it came in like this:
215090
The bag was ripped open too.
I tried to fit the two separate sprockets onto the cassette, but found no way.
Is this right?

The two loose cogs are inverted. Flip them over and try it again.

All cassettes have at least the two smallest cogs and the lockring as separate pieces.

I assume you bought this cassette on e-bay or from some on-line seller as it seems to be a "grey-market" part, i.e. resold from some manufacturer's overstock. Comercially packaged cassettes come in boxes and are assembled on a post or other retainer that keeps everything in order.

To install this cassette, place the grouped together cogs on the freehub body, then the larger of the two separate cogs with it's spacer side toward the larger ones, then the smallest cog, also with its spacer facing the others and then the lockring. You do realize thse cogs are "keyed" to the freehub body and the narrow spline on the body must be aligned with the narrow groove on the cogs?

I assume your freehub body is an 8/9/10-speed version. If it's a 7-speed body the cassette wil be too wide to fit.

The cogs don't actually fit together as one complete unit (like the old freewheels.) But once you put all the loose cogs on the hub they are made one by tightening the lockring.

I actually disassemble my cassettes on purpose to get 8 loose cogs. This makes it possible to clean everything more thouroughly.

I respectfully posit that you either have a wrong-speed cassette ( like you ordered a 9-Speed, but you have a 7-Speed), or you have no idea how to put a cassette on. There is nothing wrong with the cassette in your picture.

I think you need a bike shop.

The last cogs always come appart i dont know whats the problem, And yo uare getting lucky because the miche ones come in individual spacers and cogs so probably that could make more than bad??? Just put the cluster in, put the other 2 in there, then the lockring, is that a problem???

The old 7 sp shimano HG came in 5 speed cluster and the last 2 plus the lockring just like the stuff u have in there, again, what is the big deal if the thing is new?

Yes, there is a tool that you need to tighten the lockring to torque specification.

I say to take your bike to a bicycle shop, so they can at least show you how to do it.

Or, alternatively, you can look up "putting cassettes on bicycles" on You Tube.

Yes, you cannot put enough torque on the lockring with your bare hand.
The smallest cog on this cassette is an 11 so you will need the special lockring made for the 11. I assume that is what you got.
Most lockrings have the recommended torque shown on the lockring in neuton-meters.

I have been buying cassettes for a long time, and what HillRider was talking about is "packaging", not assembling.

In proper Shimano packaging, you still have to take the cassette apart from the plastic spline fitting to put it on your freehub.

If you plan to do any of your maintenance work you'll need that tool and others. You do not have to have a torque wrench, just be sure to get it tight enough. A loose cassette can damage an aluminum freehub, poor shifting performance, and lots of noise.

There isn't enough space in the smallest cogs to rivet them together. AFAIK Even bulk (Shimano) cassettes come on a plastic post.

It IS properly assembled, those last two sprockets never come attached to the cassette, for whatever reason. To have it assembled any further, it would have to be on the freehub body already.

Are you sure you can't find the tool locally? They're very common and cheap. They are almost always available on the ubiquitous Park Tool display rack that most bike shops have - or behind the parts counter.

Of course you'll need a torque wrench too (or do like countless people and give it a good firm tightening with a 9" wrench and you'll probably be OK.... I did that for years, but now use a torque wrench because I have one).

I really think you're being overly critical. I don't see it so much as irreputable about how that cassette came. I just see it as you being unfamiliar with how a cassette goes on. Now that you've done it, you'll probably agree that it's likely that packaging really isn't critical because there's only one way the parts can go on anyway. Having received the first cassette I ever bought "properly" packaged and assembled on the post, I think that like me, you probably would have the same difficulty because it pretty much comes apart in pieces when you take it off the post. Yea, you'd have had something to look at, but maybe you wouldjn't have done so (like me) and would have had to figure it out and/or look it up online to get it on properly.

Either way, you would have had to get help here, on a website or from your LBS because you weren't familiar with the cassette, the tool and how to use it. I'm not faulting you for not being able to do it and having to learn, btdt in spades. It's not the packaging fault though.

PS: just spent a great week cycling in OR, over McKenzie pass out to the coast and then some riding out there. Oregon is the best place in the world, especially when sunny and warm!

Maybe so, Camilo. But then I would have had no reason to ***** (Ok, this was supposed to be ("b i t c h"), because it would have been my own fault for not taking note how it fits together. This way I never had a chance, which was frustrating me.
Either way, if there is a next time I shall know - unless the damn technology gets changed again! ;)

No doubt you can. I buy lots of stuff online from Bike Tools Etc: http://www.biketoolsetc.com/, which is in Ashland, 15 miles from you. If you want to see how it's done, check out courses at United Bicycle Institute: http://www.bikeschool.com/ , also in Ashland. You are very, very close to some good resources for bicycle repair.

Once you've bought the tool, you'll use it. For one, it makes it easy to thoroughly clean the cassette. Some of my bike tools are 30 years old, yet still work perfectly. Good tools are always a wise investment.

How many possible ways did you think it could be assembled? Biggest -> Smallest -> Lockring, all evenly spaced. The two loose cogs installed upside down should have been an immediate red flag....

I can't imagine your reaction had you bought a loose cog cassette.

But without the knowledge that the two last sprockets only fit when placed onto the hub you could fiddle for eternity and scratch your head. All puzzles look simple after being explained!

I can't imagine your reaction had you bought a loose cog cassette.In such a case I certainly would have expected loose cogs. I am not a stupid man, just a first time buyer. Did you guess all these mysteries when first exposed to them?
I am really glad that there usually are reaonable and helpful members in here who have useful advice, rather than making one feel stupid.

HillRider
08-18-11, 07:00 PM
The packaging you bought really wasn't intended for the "first time purchaser", it was for the experienced mechanic who realizes how these things go together (which now includes you) and buys on price, not on convenience. Most new buyers obtain their components from a bike shop and either get retail packaging or ask the bike shop to install the part.

You are by no means alone in this. We get dozens of threads from riders who buy things from e-bay and have NO idea what they have or how it works. At least you were quite a bit beyond that level since you knew what to ask.

BTW, a lockring tool is cheap, durable and essential. It's one tool any multi-speed bike owner who want to do their own mechanical work needs. A decent chain tool is another.

I'd be shocked if you *couldn't* buy one locally.
I'd be shocked if your LBS didn't have them for sale.

I actually bought one this morning at my LBS for $5.95 (Park FR-5).
I've also seen them at most other shops in my area.

If there's an upside to all of this, it's that from reading this thread *before* I removed my own cassette, I learned that I'd likely encounter at least a couple loose cogs, not to be shocked about that, and keep track of them for reinstall.
Thanks! :thumb:

I put a new Performance/Forte 9spd cassette on my bike recently - wouldn't slide on all the way because one of the cogs needed some help with a file to fit. Had to remove the screws holding the 7 cogs together to figure out the problem and to get at the very-slightly-bad cog. (It's lighter without the screws!)
I've never used a torque wrench on cassette lock rings but do tighten them pretty tight. What kind of torque wrench is used with a lockring tool?

I use a 1/2"-square drive beam type torque wrench (Craftsman) and a 1" socket with my Park FR-5 tool or a 15/16" socket with the Shimano TL-HG16 tool (I don't have the proper 24 mm socket but the 15/16" fits fine).

I have accessory centerpins in both tools to keep them in place under load for either removing or installing the lockring. I have also used a qr skewer to hold it in place before I got the centerpin versions.

Most importantly, you need a torque wrench that can reach at least 40 N*m (30 ft.*lbs.) for Shimano cassettes and apparently a bit more for Campagnolo (50 N*m based on a quick Google search). I use my 3/8" drive torque wrench for this as my 1/2" drive starts at 25 ft.*lbs. and I trust it less that low in it's range (it goes up to 250 ft.*lbs.). Since my 1" drive socket is a 1/2" drive impact socket (originally bought to use with some automotive suspension tools), I use a 1/2" to 3/8" drive adapter as well.

The short story is don't buy a 1/4" drive torque wrench and expect to be able to tighten cassette lockrings properly.

O - pick up one of Lennard Zinn's bicycle repair and maintenance books, or one of Todd Downs' similar books -- each describes the various technologies and standards used for diferent bike parts, shows the tools needed for different procedures, and each is likely to be available in your local library if you don't want to help out Jeff Bezos.

Juha

I see jds108 beat me to it.

Again, you can tighten the locknut with just the lockring tool and a wrench. Opening the locknut (for cleaning, replacing spokes, whatever) will be more difficult, because the whole cassette turns freely in that direction, together with the lockring. You need something to hold the cassette in place while you crank the lockring open, and your hands won't do it. That's what a chainwhip is for. If you buy a lockring tool, buy a chainwhip as well.
