I messed up big time. I purchased some Ultegra WH 6600 wheels thinking all shimano free hubs use the same pattern and I'd be able to fit my 105 gears on it.

Well I can't. I did notice that the hub comes off (is that what it's called? A hub?) i thought maybe i could buy a hub that fits my 105 gears and be all awesome.

If i can't, does that mean i have to upgrade my shifter, derailleur, and cogs? That's expensive.

dtrain

Which 105 'gears' exactly? What 'speed'? Most 8, 9, or 10 speed cassettes (gear cluster) should work...I think. Is your 105 cassette an 11-speed 5800?

9 speed shimano 105 5503

I'm willing to buy a new cassette. But I don't see any 9 speed ultegra 6600 ones. What's the cheapest option to integrate these wheels into my set up?

dtrain

I wasn't familiar with those wheels. Looks they only run 10-speed Shimano cassettes. Shimano only went down that road briefly...most of their stuff is backwards compatible (8, 9, and 10 - etc.).

I doubt that it would be possible (or worth it) to change out the freehub body...but I'm no expert.

6600 is 10 speed, so unfortunately you won't find a 9-speed one (that would be a 6500 cassette...and wouldn't fit).

So I guess you either sell (at least) the real wheel and buy something else - or upgrade the rear shifter, chain, and cassette.

You can run 10-speed 6700 cassettes on the WH6600. TTBoMK

Edited to add, you can lock out the top gear with the high limit screw. It'll still shuffle the gears fine for 9 speeds.

You can replace the freehub body using a 5mm wrench, a new freehub is about $50, some examples here.

i know of no reason why the freehub cannot be replaced with the more standard 10-speed freehub. to my knowledge the attachment design is the same.

although i'm all good with being proven wrong.

if it works, here's one you can get for less than 20 delivered:

Can i take the hub from my old shimano 105 hub?

trunolimit

Alright so my current plan is to just get the 10 speed cassette, 10 speed chain and use the limit screw so i can keep my 105 9 speed for a little while longer. The shifter is acting up so i plan on replacing it sometime in the future.

My bike has become sort of a Frankenstein.

I don't think that will work very well. The spacing on the cassette won't match the throw of the shifter.
I did something like that by mistake once (9 speed cassette on 8 speed bike) and it was annoying as hell.

trunolimit

That makes me a sad panda

cale

I've read that when Shimano changed Dura Ace to 10 speeds, 2004, they fit the new cogs in the same space and retained the same spacing. The chain and cogs are narrower, so shifter performance should be unaffected. https://fitwerx.com/converting-wheels-to-10-speed

dtrain

Partially correct...but you are making the wrong conclusion at the end. Same overall width of the shell body, but not the same cassette spacing. Spacing gaps are narrower as well as the cogs in order to fit 10 in the space that was filled by just 8 or 9 previously.

dtrain

If the wh-6600 body comes off that easily, it might be worth trying the one from your older 105 hub.

cale

My bad. The difference in center to center spacing seems so minor.

trunolimit

I tried taking the old hub off but can't figure out how to do it. This tells me they aren't compatible because the 6600 snaps in easily. Plus the names are different i noticed. The 105 is something glide while the ultegra is CS-6600.

I fixed my old rear wheel by taking a spoke from the front wheel and putting it into the spot of the broken one. I have a park tension meter and i tensioned it to match the rest of the spokes on the non drive side. No hops and it runs true so it seems I've bought myself time.

Let me ask is it ok to keep my front gear configuration? So the front would be shimano 5300 3 speed and the rear will be ultegra 6600 10 speed?

Found this on Sheldon's site.

Alternate Cable Routings
Two alternate cable routings for Shimano derailers adapt them for use with nonstandard shifters or cassettes.

Shimano originally publicized an alternate cable routing which placed the cable slightly closer to the pivot, making the derailer move slightly farther for each click. This adaptation makes newer Shimano derailers work with older Dura-Ace shifters, but it is also useful when you want to use a 9-speed cassette with 10 speed shifters, or 8-speed cassette with 9-speed shifters, or a 7-speed cluster with 8-speed shifters. You may need to fine-tune the amount the cable deviates from the standard position, so the derailer sweep matches the sprocket spacing.

cable routing to increase derailer travel

The other alternate cable routing, suggested by Brian Jenks, proprietor of Hubbub Cycles, decreases the derailer travel for each click. This makes some Shimano derailers and shifters compatible with Campagnolo cassettes. It is also useful when you want to use a 10-speed cassette with 9-speed shifters, or 9-speed cassette with 8-speed shifters, or an 8-speed cassette with 7-speed shifters. You will then lose the use of one sprocket, unless you are using a shortened cassette such as an 8 of 9 on 7, or 9 of 10 on 7. Note the two tabbed washers in the drawing below -- one to change the cable routing, and the other to secure the cable. Again, you may need to fine-tune the cable position.

cable routing to increase derailer travel

Unlike the Dura-Ace modification, the Hubbub modification is nonstandard, and not all of the ratio changes are accurate. Chris Juden of the Cyclist Touring Club (U.K.) has posted a Web page listing usable combinations. Pulley-type adapters from JTek Engineering offer a more precise alternative.

This chart looks really interesting. https://cycle.shimano-eu.com/publish/...harts_2009.pdf


I found a ST 5600 for 50 bucks on ebay. Bringing the grand total to upgrade the whole rear drive train to a little over 100 bucks. Add the 200 bucks i paid for the wh 6600 wheels (upgraded from mavic cxp21 with shimano 10 5300 hubs) and that means about 300 bucks for what i consider a major upgrade in performance and strength.

Not bad? Or am i kidding myself.

Looks like HG-50, Tiagra 9-speed, cassette is compatible with WH-6600. Shimano Tiagra HG50 9 Speed Road Cassette | Chain Reaction Cycles

trunolimit

But does that 9 speed work with the 105 5300 rd and shifter?

CliffordK

NO!!!!!

Compare to:
EV-FH-5600-2458C.pdf

The freehub bodies are entirely different

Since the WH-6600 is a non-standard Shimano freehub, you'll have to do some hunting to find a 9s or 11s replacement. Perhaps another brand would fit??? Or, maybe there is a Shimano version.

I think the freehubs are compatible except for the depth of the teeth, so you could probably mill down the teeth on the freehub. It would be a pain to do on a lathe, but you could do it on a milling machine, or cut them down freehand.

You might be able to find a replacement hub, but you'll have to do some hunting if you want center nipples with straight-pull spokes.

I'd probably sell the wheels and buy what I wanted.

CliffordK

The problem is the 10s aluminum freehubs had deep splines.




The deep spline cassettes will work on any Shimano Uniglide compatible freehub.
But, not the other way around.

The shallow spline cassettes (9s & 11s) won't work on the 10s deep spline cassette bodies.

By moving to Titanium, Shimano eliminated the need for the deep splines.

dtrain

Hubbub is worth a try for sure...but you need the 10 speed cassette to try it. Personally I'd just be trying to sell the rear wheel or wheelset at this point.

trunolimit

Yeah trying to get my money back for the wheels is probably the best thing but honestly besides the shifter the ultegra 6600 set is not that expensive and it would be a nice upgrade.

So i was wrong about the 105 set i have. I have the 5500 group set installed. Except for the front shifter and derailer. I had to change it to 105 st-5603 shifter and the matching derailer due to damange on the old 5503.

mercator

You certainly seem to have a mix of parts on your bike. Not telling you what to do, but if you are thinking of spending $300 for a new shifter and related parts, why not just get a whole new 10-speed groupset for a bit more?

I just bought this to put on my old Lemond - which was running 8 speed 105 - and it is really quite nice.
