This is confusing because here is a picture of my hub



it looks like the 9sp one in your picture. Yet I tried to put my 9sp 5500 cassette in there and it won't fit beyond those steps. I did purchase the CS-HG50 so thanks Cale for that. I will try to put it on when I get home tonight. However I opened up the package and the CS-HG50 looks like it's the same size as my current cassette. Hopefully it's just that my perception is off. We'll find out tonight. The guy at the bike shop told me it should all work together. If it doesn't he said I could bring it back.

That Tigra set does look sweet. But it would only be an additional 118 bucks to upgrade to a 10sp set up. I'm just fixing stuff as I go along. My Front derailleur broke so I replaced it with another 3 speed, my front shifter broke so I replaced it with the one matching my derailleur. What prompted me to get the wheels was that I keep breaking spokes so in looking for a stronger wheel I came across the WH-6600 set for 200 bucks. straight pulled spokes hopefully will take my abuse a lot better.

Sorry, there were two pictures from different sources.
Top picture, left is 9/11 compatible.
Top picture, right is 10 speed.

Bottom picture left is 10 speed
Bottom picture right is 9 speed.

Yours is the 10 speed.

So, you have a choice of upgrading your cassette, shifters, chain, and perhaps derailleur to 10 speed compatible.
Or, getting a different rear freehub.

As mentioned, I doubt ANY Shimano 9 speed cassette will work with your freehub.

trunolimit

Well we will see tonight but if it doesn't fit (which I think you are right from the looks of it) I don't mind up grading to 10 speed.

As far as the compatibility chart goes. I'm a big dummy yet again. The chart states it's compatible with FH-6600. My wheel has WH-6600. Totally different hubs.

snotrockets

No it won't. The spacing is different (ref)

CliffordK

I haven't looked at the cribsheet closely. However, 9 & 10 speed cassettes should be interchangeable EXCEPT with the case of aluminum freehubs which you apparently got.

There is the JTek Shiftmate which apparently has rapidly vanishing stock, but in theory could convert from a 10s to 9s and visa versa.

snotrockets

To reiterate what others wrote here, and what I know to be true:

Shimano 8 and 9 speed cassettes are interchangeable.

Shimano 10 has the same pattern, but taller splines on the cassette, making it fit on an 8/9 freehub body. It doesn't always hold the other way, as there are freehub bodies with the taller splines (such is the body on the WH-6600), which only fits 10 speed cassettes.

11 speed use the same spline pattern as 8/9, but is longer, so you could fit 8/9/10 speed cassettes to an 11 speed body using a spacer, but you need a new freehub body to run 11 speeds.
The 11 speed has the 8/9 shorter notches, so you can't fit it a 10 speed cassette on WH-6600, even if you can magically add a few more mms to it (and you can't).

By changing the pull ratio. But you can't run stock 9 speed with 10-speed cassette. Been there, tried everything, didn't work.

snotrockets

You can get a 11 speed group for not much more.

I wouldn't upgrade 8 to 10 speeds, with the 11 speeds now phasing the latter out.
If you're upgrading, sell the wheels, get 11 speed compatible ones, and a new 11-speed group for almost the same price.

mercator

Well, that's an option too, although like me the OP already has 10 speed wheels, which is why I'm sticking with 10 speed.
Also, there is no 11 speed group available at the same price as the Tiagra.

snotrockets

At $375, I consider this close enough: Shimano 105 5800 11 Speed Groupset - Black - 53/39 | ProBikeKit.com

I'd upgrade to 11 speeds in an instant, if not for needing new wheels. I guess I'll just save for a new bike.

Welcome to the discussion.

trunolimit

And.........it doesnt fit.

Ok so the question is dose the 105 ST5600 shifter work with the RD6600 that I'm about to purchase?

CliffordK

Take a breath before going to the store and buying one of each Hopefully you can return the cassette if you don't use it.

The ST5600 shifter and the RD6600 derailleurs should be compatible, and 10 speed.

According to this:
Bicycles/Maintenance and Repair/Gear-changing Dimensions - Wikibooks, open books for an open world

Most Shimano derailleurs (except some early Dura Ace) should have a 1.7 cable pull, at least through 10 speed.
It isn't clear if 11s was updated.

So, your Shimano 10s shifters may work with a 9s derailleur, you'll have to test them.
Likewise, your Shimano 10s derailleur SHOULD work with 9s shifters.

6600 and 6700 should be generally interchangeable.

I've been running 9s with a really old, totally inappropriate derailleur. What I've found is:

• Older models of derailleurs had more jockey wheel play than newer ones. The extra play can cause shifting problems for indexed shifting.
• Newer derailleurs have a stronger return spring for more positive shifting into the high gears (small sprockets).
• Use the minimal derailleur clearance (B-Screw adjustment) possible to minimize chain flex.

Anyway, you can purchase either an RD6700 or RD6600, but I would test whatever derailleur you already have.

Someone above mentioned the Shiftmate. It does work very well for allowing me to use my 10spd shifters (I think they are 6600) with a 9spd cassette. If the cable routing is reversed it should allow a 9spd shifter to work with a 10spd cassette, though there shouldn't be enough clicks to use all the gears and you'd lose either your bottom or top cog.

I never had much luck with changing the anchor position to get the mixed parts to work. Seemed I'd get fine shifting at one end of the cassette and lousy at the other end.

Wow, this has really gone off the wall! You have gotten some good advise but some have posted who obviously have no clue. Try the "Mechanics" forum next time! To summarize, your wheels will accept only ten speed cassettes. Move on. If you want to use a 10 speed cassette, you can still use your 9 speed front and rear derailleurs. You will need 10 speed shifter for the rear. You cannot "lock out" one of the gears and use 9 speed shifters. You cannot put a Tiagra or any other 9 speed cassette on your wheels. Sorry you were led astray.

cale

You know, I said that I wasn't certain a day or so ago and about forty messages back. Geez, the guy bought a cheap freewheel at a LBS, with the promise that he could return it if it didn't work, and will have to return it.

I been accused, rightly, of being wrong. But being accused of trying to help when you're nowhere to be found? Get over your sanctimonious self.

shelbyfv

I didn't name names but you obviously recognized that the shoe fit. Clearly you had no knowledge of the issue but felt compelled to post and thus confused the thread and wasted the OP's time.

cale

Troll.

trunolimit

Hey I appreciate everything you guys have taught me. That's why I love forums. We all learned something through this experience and are better people for it. One thing that doesn't translate well across the internet is tone. I doubt anyone here means anything they say in a condescending or mean way.

Yeah You're right, wrong place to have posted this.

So the conclusion to my saga is I purchased the following items:

RD-6600
ST-5600
CS-6600
CN-6600

Can't wait to get them on and see what an extra gear feels like. I do wonder about chain rub though. Right now I get chain rub when I'm at the opposite extremes (first gear on the front last gear on the back or last gear on the front and first gear on the back) . Adding an extra gear will probably increase chain rub.

Also I read that the rear gears tend to cut notches into an aluminum free hub that's why aluminum free hubs are bad even though they do save some weight.

One more newbie question, will I need a special sized tool to put the cassette in? I have the tool for the 9 speed.

Again I can't thank you guys enough.

Edit: OK maybe he was being a bit mean.

dtrain

You purchased all that in order to make this wheelset work for you? Wow.

cale

I love it! A great big beautiful bike project! You're going to have fun. Sorry about the cogs. I guess that like you, I wanted to believe there was a solution.

RD-6600 Ten-speed Ultegra rear derailleur. Sounds great.

ST-5600 10-speed 105 shifters. You can also look at ST-5700 10-speed 105 shifters and ST-R700 which are a Ultegra-grade shifter without group designation. (Though Shimano references to the ST-5600 service instructions.) Sample auction, Shimano R701 R700 2 x 10 20SPD Left Right Double STI Shifter Dual Control Lever | eBay

CS-6600 10-speed Ultegra cassette. Uh-huh.

CN-6600 10-speed Ultegra chain. Sounds right.

Good luck.

shelbyfv

The cassette tool is the same for 7,8,9,10,11.

trunolimit

Yeah the way I rationalize it is at 200 bucks what wheelset could I have gotten that was better than these? I looked around and there was 1 other set I was considering but I had to have the straight pulled spokes (having snapped several spokes on 2 different sets of cheapo wheels).

I've been having trouble with my right shifter not shifting at times. It's really weird, it feels like there is no tension and then i just keep trying until I feel the cable pull. So I've been meaning to change the shifter, having changed the cable and housing already.

So this just makes sense to me since I'm gaining some nice wheels and getting rid of a problem shifter.

dtrain

Okay. Enough said. ^ That's all that matters. Enjoy!
