I'm currently running a 105 11-speed 10-28 on my commuting bike.
Approaching winter I'd like to switch the bike wheels for a set from my MTB. I've managed the front with a 15mm to QR adapter the rear is a bit more of a problem.
Is it possible to run a 11S road cassette on a 10S XT Hub assuming I remove one of the cogs? If so what spacer would I need (on the inside or outside?) and is it likely the limit screw on the rear derailleur would be enough to prevent the chain coming off if I were to over shift or would I just need to be extra careful?
I have run a 105 cassette with 1 ring removed.
I believe the new 34t Ultegra cassette fits a mtb 10speed freehub so that may be an option.
I saw the Ultegra cassette but I don't really want to splash out that much on a cassette for winter use in Glasgow!
Yep to new ultegra fitting standard Shimano MTB freehub out of the box with no messing.
Otherwise 11sp Road needs a longer than standard Shimano 10sp freehub. Some manufacturers were already making suitable freehubs to avoid licensing so there’s a bit of suck it and see.
If your 11sp cassette doesn’t fit your 10sp hub then the Ultegra cassette is probably the cheapest solution regardless of being Ultegra.
Other solutions if you want a cheaper cassette are probably going to involve replacing levers and derailleurs or rebuilding wheel with a new hub.
Neither of which needs to be expensive particularly if you picked up a SH 5600, 5700 kit or similar but both are way more time to implement then a cassette swap.
Other leftfield idea is dropping the wheelswap plan and either getting a suitable set of wheels or just leaving the bike as is.
I think there's now a 105 equivalent of the 11-34 ultegra (hg700?)
If you go down the route of removing a sprocket, set the limit screws as normal (i.e. for the remaining 10 gears) then index it so that the missing click is at the cable releasing end so you can't push against it with the shifter.
Dunno if it applied to every cassette, but on some 11-whatever cassettes the 12t and 13t sprockets are the same as the ones used on 12- and 13- cassettes and already have the knurling for the lockring so turning 11-28 11s into a 12-28 10s with 11s spacing is simple, just add spacers behind the cassette so it's snug.
Thanks, I'd not come across the hg700 before, looks like it is the ultegra equivalent in 105.
This would have been ideal but for the fact that it looks like I've got a standard length rear derailleur (and it seems not to be readily [or at least cheaply] available in the UK) so would end up not much better off than running with a cog removed (would lose the 34T rather than the 11T though).
I'm going to pick up another 105 11-28 cassette and see how I get on running it as a 10S.
I've recently gone for an 11 speed conversion on my Hope XC rear hub. This is 10 speed only but have done a couple of mods to run an 11 speed cassette on the hub. I've machine 1mm off the flange at the base of the freehub body and fitted a 'Token' locknut ring as they have a deeper thread than a standard Shimano lockring to compensate for the additional 0.8mm of cassette width. It seems ok so far and can't foresee any issues.
I did a fair bit of googling beforehand and there are quite a few decent bodge solutions depending on the design of your freehub body and cassette by either removing material off one or the other to run the full complement of 11 ratios.
10 speed casette will be fine with 11sp shifters. there's just an extra click.
Just take a file to the stop on each ridge of the free hub. 1.8mm or there abouts. Still leaves enough material to do the job and then any cassette fits .
Shimano are not as tough as you would hope and file easily. Hope freehubs are made of cheese.
Sunrace and SRAM do cheaper 11 speed cassettes that fit on a 10 speed freehub

No, it won't, stop talking bollocks.
I machined a bit off a 105 11 speed cassette to fit it onto a Hope XC hub. See thread here
Easy job if you want me to have a go.
No, it won’t, stop talking bollocks.
Come ride my bike then tell me again! works perfectly.
10 speed road SRAM 'should' work fine with 11 speed shifters

You may be happy with how it shifts but the fact is, the spacing between the individual cogs is different between 10 and 11spd and it will never shift *perfectly*
To state as fact that the only difference is an extra click, is as I said before, bollocks.

Depends on what parts you've mixed: Tiagra 4600 and current road 11speed will work because (IIRC) they use the same cable Pull, any other shimano 10 speed shifter will not play properly with an 11 speed mech...
But this is all sort of irrelevant to the OP who already has an 11 speed drivetrain and just needs to get a cassette to play nicely with a hub...

4700 🙂
Yeah alright, it's only an extra 100 😉

No that's the 2020 SRAM Super-Golden-Eagle 14speed 10-100 cassette, It's compatible but you have to mount the mech upside down otherwise it hits the ground.
