I'm beginning to research Shimano hubs for my Raleigh Roker. I need a disc brake hub for a 12x142 thru axle. I'm looking at two hubs, the SLX FH-M7010 and the more expensive RS770.

I plan to use an 11-speed road cassette, alternatively the Shimano CS-5800 and a Sram PG-1130.

I'm beginning discover that the SLK FH-M7010 will take a 10-speed road cassette or the new 11-speed CS-HG800 11-speed 11-34 cassette. However, it won't take an 11-speed road cassette including the CS-5800. It's unclear to me if the RS770 accepts a road 11-speed cassette.

Does Shimano make rear hubs that accepts both a 12x142 axle and a 11-speed CS-5800 road cassette?

you can use a mountain hub and a spacer and it'll be just fine.

Unless I’m missing something, that won’t work for 11 sod road cassettes.

The Shimano compatibility chart shows the RS770 hubs in the road section and compatible with the 5800/6800/9000 cassettes. You could also install mountain cassettes with a spacer. I believe the tradeoff for fitting road-range cassettes is more wheel dish, hopefully one of the resident wheelbuilders can confirm.

I could have them backwards.  I'm on pain meds and it happens.

I was going down that exact rabbit hole in the last few days.  My thoughts:  If I'm paying $160 for the hub (RS770), then another $50 to have someone lace & dish the wheel, aren't I 2/3 of the way towards a new wheel altogether with possibly better components?  Wheelbuilders, let me know how far off I am.

Thanks.

Several sellers on eBay are offering the rear RS770 hub for $88, This includes shipping. I'm now focused on this hub and the XT HB-M8010 front hub. These hubs are a huge upgrade over the OEM hubs on most gravel bikes.

OK, I saw most of them for $88 for the front hub.  There are a few for the rear hub as well, which I find odd.  Hopefully they won't be labeled "Shimanno"  Now I need to count my spokes. . .

Are you planning on using an existing rim and spoke set.  Best to be sure the spoke length will work with the new hub body.  Yes you need to redish the wheel for the road cassette.

Ekh.

A few thoughts, FWIW:

1)  As drwelby noted, the RS770 rear hub will work with your 11 speed road cassettes.

2) If you're starting fresh with a new wheel build, another hub to consider is a DT Swiss 350 12x142.  The hub comes with a freehub body that will only accept a 10 speed road cassette.  However, you can purchase a DT 11 speed road freehub body and swap it out pretty easily.  The downside is cost, as DT bits do not come cheaply.  But since DT hubs are convertible to different spacing/axle standards, you may buy yourself some flexibility.  In the event you want to use the wheel on a bike with different spacing at some point, you can swap the end caps to get the configuration you need.

3) Another alternative to consider is using 10 cogs from an 11 speed road cassette on an MTB hub, like the FH-M7010.  You can drop a cog from your road cassette, and add an 11 speed cassette spacer behind the cassette to create a "10 speed" cassette with 11 speed spacing.  Just adjust the limit screws on your rear derailleur to match the width of the cassette.  I've done this on at least half a dozen setups--it works perfectly.  The downside here is that you lose one gear, but consider the range you need and the gearing afforded by your chainrings and assess whether you can get by with "just" 10.  For example, if you're running a 50/34 crankset, dropping the 11T cog on either of the cassettes you mentioned would leave you a highest gear of 50/12, which is still a pretty big gear for gravel (at least for me).  The upside is that it opens up the range of possible hubs or wheels you can use and may end up saving you some money.

I took the dive and ordered the Shimano RS 770 rear hub from Amazon Prime for $82. It's the only Shimano hub that uses a 12x142 axle and takes a road 11-speed cassette that I could identify. It also seems to be Ultegra level quality at a bargain price.

I'm a little surprised that I could find only one Shimano road hub that accepts an 11 speed road cassette for a thru-axle disc brake bikes. Not only are most contemporary gravel and Cyclocross bikes using this configuration, but many disc brake road bikes are also using this thru-axle standard.

Shimano has two 11 speed wheelsets that are thru-axle: WH-R9170 and WH-RS170. They might be trying to push people towards the completes, or it could just be Shimano being Shimano.

Did you check the spoke length calculator to see if you could just swap the hub?  I'm back to thinking that if I have to buy spokes, then I might as well just go with a custom build.

I'm assuming that I'll need new spokes.

I do think you have it mixed. Here is my understanding. Shimano MTB hubs can fit 10 or 11 speed MTB cassettes with no spacers as Shimano 10 and 11 speed MTB cogs are the same width. 

Shimano 10 and 11 speed road cassettes are not the same width. A 11 speed road is wider and can only fit on 11 speed road hubs. However you can use an 11 speed mtb, 10 speed MTB, 10 speed road, 9 speed road, .... on a 11 speed hub with a spacer. Currently I am using a 9 speed cassette on a 11 speed hub with a spacer. In the spring I am moving to 11 speed and plan to run both 11 speed road and 11 speed MTB with a spacer.

I had wheels built last year for my Willard which runs Shimano 105 11-speed. The builder used DT Swiss 350 hubs with spacers to make it work. I am not up on all of the specs, but I -think- that's a mtb hub? Anyway, that's one combination that worked for a Shimano 11-speed + Disc brake setup.

The 350 is also available as a road hub with road cassette spacing.

You are correct, but it is not necessary to swap the freehub, because DT has an 11 speed road disc hub.

It is almost invariably unlikely that spoke lengths are going to work from one wheel to the next, so you'll have to add the cost of spokes to that, too.  There are exceptions, but most builders do not want to mess with used spokes anyway.

The cost of a new custom set might surprise you.

Shimano is finally catching up.  Maybe they thought "gravel" was a fad, or disc brakes on road bikes would die?  [rofl]

Good to know!  I thought they must, but I couldn't find where there was one specifically specced for road 11.  I'm sure I was overlooking the obvious.

I was looking at Amazon, trying to figure out why they could offer that hub so cheap.  I'm thinking there is a mistake.  

Did you actually get a rear hub for $82?

So I was able to rebuild the rear wheel with the new Shimano RS 770 hub, SM-RT81 disc and DT Swiss Competition (double butted) spokes for $190. I think I'll be happy with the upgrade.
