11 speed Ultegra R8000 Cassette wont fit on NOVATEC HUB

So I've found that this Novatec Hub is ONLY for a 10 Speed Shimano cassette. Sooooo Frustrating, I want these wheels on my bike like ASAP. My local LBS couldn't help so I contacted Novatec, no word back yet. DOES Anyone have a fix for this besides buying another wheel?

Thanks in advance.

Shimano CS-HG700-11 or CS-HG800-11 11-34 cassette, if your RD will handle it. You will need a new (longer) chain.

Those will fit this hub? With no dishing wheels or what not ?

Yes. Without the supplied spacer, they will fit a standard 10-speed road hub.

A more expensive option, but with more gear ratios, is a monoblock cassette and their special lockring.

That looks as if it might be one of those weird "10 speed only" freehubs. The stairstep spline? If that's the case none of the 11s will fit. Google it, I'm no expert.

No, this is a 10S only body.
The taller splines will only accept 10S cassettes. (that start with an 11 or 12 sprocket from the 7800, 7900, 6600, 6700, 5600, or 5700 series, so no junior cassettes or 4600 or 4700 either)

I'd return those wheels.
ETA: If they were bought recently. OR...when you eventually get in touch w/ Novatec you can most likely get a different freehub, possibly they have an 11 speed that will work.

It's pretty easy to swap the freehub bodies on Novatec hubs. Contact BDop Cycling https://bdopcycling.com/novatec-hub-parts-2/ They should be able to help you get the correct freehub.

There seems to be two camps.

One says 10 speed only so no 11 speed cassettes will work.

The other camp says 10 speed only so only 11 speed mtb cassettes without the spacer will work.

Bit then the other camp can start an internet platform and rally around each other to convince themselves they are right.

Isn’t believing you’re right more important than actually being right?

And I guess there is a third camp that just doesn’t care... lol!

This. These folks know their stuff IME and since they also sell cassettes under their own label they probably know what works and what doesn't on each freehub. if you need a new freehub they have them and you can sell your other one to cut your losses.

Given Ultegra cassettes have a carrier for the larger cogs, if one of the cogs on the carrier has a tooth count that's a multiple of three, you can grab it in a lathe and turn off 1.85mm.

Pretty sure that'd work; I have a billet 10s cassette that's been molested like this to fit on a 7s cassette body, which I retrofit onto a RS80 to make it stronger, and a bit lighter, not to mention really optimise the packaging; RD cage runs minimum acceptable gap to spokes, no room for the chain behind the largest cog, it's pretty sweet.

This is why I maintain a longer cassette body for 11s was a mistake. It wasn't necessary for wheels to be made weaker for it; there was plenty of room to tighten up the packaging. If I can jam 10 cogs into the space of 7 with flying colours, 11 into the space of 10 should've been easy.

What kind of 7? 7 on a 126mm hub or a 130-135mm hub?

The camp that chose 10s only was correct. Novatec is trying to help me resolve it. Ill post back. So far they have been great to help me.

Did they offer a response on mtb 11 speed cassettes that have a recessed large cog?

I have seen the file method to remove 1.5mm off the spline cassette stops. Seems a bit primitive, I’d prefer a lathe. But if a person can start a fire with sticks, fitting an 11 speed cassette with a hand file can’t be that tough.

Congrats!

I guess that means no hand file mod.

But you can still start a fire with 2 sticks.

Well, the wheel was in a modern bike, so I kept the axle. IIRC it went together at 131 or 132 with the spacers, washers and nuts I first tried, so I figured hell yeah, go for broke, since the frame opened up that far with the wheel unclamped.

Added like a turn and a half to the NDS tension. Off-centre rim on the RS80 already, so rendered bulletproof.

The 130 mm hub was designed for 8-speed clusters. Hubs had been 120 mm for maybe 2 decades when 4- and 5-speed freewheels were the limit. Pros started using 6-speed freewheels on a 126.5 mm hub in the early 1970s, and later that decade SunTour squeezed 7 cogs on that axle by closing the spacing and developing a chain that had a narrower outside width. Other freewheel and chain manufacturers followed suit. 8-speed uses the same spacing as 7 but on a 130 mm axle. 9 and 10 closed the spacing some more. 11 basically uses 10-speed spacing but basically moves the drive side hub flange inside by another 1.85 mm.

Mountain bikes use wider rear hubs for added strength and accommodating disc brake rotors.

You're correct that 130 came about for 8s, but a couple of the other details are wrong...

8s uses the same spacing as 7s only for Campy, which is the same 5mm as Shimano 7s. Shimano 8s is 4.8mm.

11s spacing is tighter than 10s spacing, as evidenced by both the fact that it made Shimano and Campy effectively compatible, and that it was necessary to develop a whole new chain with separate bushings pressed into the inner plates, because the radius from stamping them in cost precious bearing area.

Replace your 10s chains with 11s. It has the same inner width as 10s, the narrower outer width makes for quieter running with less chain rub, and it has more wear surface. Another tip for those interested in extending chain life is to bung larger pulleys in your derailleur and run more chain length. I fit 13/15 in a SRAM Red unit, reckon it could've fit 14/16. That's on a short cage without busting out the Dremel.

.
Thanks for correcting me on 8- and 11-speed. I checked with Sheldon, and it looks like 4.8 became standard for 8-speed when Shimano and SRAM migrated to cassettes. Also, 10- and 11-speed Campagnolo spacing is "variable," which is why i always zip-tied these cassettes when I swapped or washed them.
