This is EXACTLY what I needed to know. My new 12 speed ultegra will be here in December and I wanted to swap my ENVE wheels from my 11 speed DuraAce. Thanks for this!
Ok - so the reason landed on this is because my 11speed freehub would not engage with the threaded cap after all the gears were on and I wanted to be sure 11 and 12 speed freehubs truly were compatilble as I'd heard. All the issues covered in this video I found to be mostly common sense. Just install the cassette in the order it comes in the package, right? In my case an extra spacer had been left on the inside of the freehub body from the 11spd cassette. Removed it and oila - perfeto.
Almost the same here, I bought a shop groupset (comes in brown bags instead of shiny boxes) and the cassette had three spacers, all different thickness. how many did you use 😄
@@Bultish Speaking of my own experience with Shimano Ultegra 11spd and Dura-Ace 12 - All the spacers for the given cassette were used. If installing an 11spd cassette there is an "extra" spacer that goes on first, against the flange of the freehub. A 12 spd cassette does not have this. That extra spacer is what was inadvertently left on the freehub when I swapped wheels from 11 - 12 speed cassettes.
Thanks for your video! So i can put my 12 speed shimano 105 onto this? And it’ll be able to use all 12 gears? Looking to upgrade wheels to dt Swiss 1600.
I am running shimano ultegra 11 speed group set. Planning to buy a new wheelset shimano duraace 9270 and shimano says that this wheelset is only compatible with 12 speed. Can I use it with my existing 11 speed ultegra group set?
No...Shimano have decided to make the Ultegra and DuraAce wheels not backwards-compatible with 11 speed cassettes. They're the only company (that I'm aware of) who does this so wheels from another company (such as us!) will be fine -Tristan
I have a disc with a 10 speed hub, I machined the back off an 11 speed cassette to make it fit, do you think I will be able to do the same with these cassettes?
The new 12 speed cassette can be run on 11 speed wheels, however the new 12 speed Dura Ace wheels are incompatible with 11 speed cassettes for those who are currently running 11 speed Shimano group sets and wanted to upgrade to the new Dura Ace C36 12 speed wheels on their 11 speed drivetrains. Intentionally designed incompatibility by Shimano once again. :-)
There's good reason behind this design. That hub has been compatible with a lot of cassettes for a very long time. Totally fair to not keep it indefinitely for an improvement at the high end.
Many thanks for your video this is exactly what I want to know, basically I’d like to mount my 12s Ultegra cassette on my 50mm Carbon wheels with 11s hub
From all of the measuring I've done the 11 and 12 speed cranks and chainrings seem to be identical. I ran 11 speed rings until the 12 speed were available and had no issues ~Tristan
Okay, thank you! I do have a specific detail question. I run a Dura Ace 9 speed mounted on a 2003 Trek 5900. I'm planning on switching to a mechanical 11 speed cassette with the largest cog being a 34. Considering the important point, the 16 tooth cog, if I change the free hub (maybe that's not needed), can I consider the 12 speed option? The bike measures 130mm in the rear and has rim brakes. Thanks for any guidance.
You can use this tool to see what freehub body you need: www.wheelworks.co.nz/what-freehub-body-do-i-need/ Your 2003 era bike is probably HG35mm. You should be able to install an 11 speed cassette with a 34t large cog on it. -Tristan
I'll let you know: I'll be using the Quarq D9100 powermeter and 9100 chainrings when my groupset arrives. Apparently the bolt-circle is the same but the chainrings are not interchangeable because of the way they fit around the spider. -Tristan
@@simonacker We didn't have a huge amount of time this morning but my understanding is that the chain inner-width is similar and that you can use the 11 speed chainrings with the 12 speed chain. The 12 speed chain is the same SKU as the mountain bike item now, and this compatibility is certainly true on mountain bike chainrings so fingers crossed! -Tristan
You might need to add some B-tension to the rear derailleur and you'll possibly need a new (longer) chain but this will depend on how your bike was initially built -Tristan
I’m running an ultegra 11 speed mechanical groupset with rim brakes and rotor 52/36 cranks. I’d like to upgrade to SRAM 12 speed Earp FD, RD, and shifters along with sram rim brakes. I don’t think my rear wheel’s free hub can be changed for a sram XDR though to fit a 12 speed sram cassette. Could I use a shimano 12 speed cassette in this case and if so would it be better to run a shimano or sram 12 speed chain? Thanks!
Hi Don. Spacing between the two cassettes is pretty similar so the Shimano 12 will work reasonably well. You'll be best to use a Shimano chain with the Shimano cassette -Tristan
I have an Ultegra 11 speed cassette Di2 road/hybrid bike, I just got some new wheels and put a 12 speed Ultegra cassette on them - If I put them on my bike will all the gearing/shifting be a mess?
It's always best to pair the chain and cassette. The Shimano 12 speed chain is narrower than the 11 speed so I'm not surprised you're having issues. TT
I got this cassette as an upgrade to my dura ace 11 speed 11-30. But now i have to return it bcos this cassette will not work with my 11 speed dura ace group set shifters etc. thats what my mechanic friend told. Correct me if i am wrong.
@@rafaeldegiacomoaraujo8778 but doesn’t that result in sub-optimal functioning when changing gears as the front derailleur won’t be perfectly aligned to the 11 speed cassette?
@@robertoalimonti5377 Sorry. I thought you meant the you were going to use a bike that has dura ace 12 speed. You cannot mix groupsets that have different speeds. But you can fit a 12 speed cassette on your kicker and run with a 12 speed shimano groupset.

Did you watch the video? -Tristan
My bike has 11 gears.

@@WheelworksHandcraftedWheels I thought the 11sp chainrings weren't compatible with the 12sp chain? May have got that round the wrong way.

This might be a dumb question but do you have to re index the gears/shifter for the extra cog or do you just click an extra click?
the shifter/derialleur handle the extra gears
Thanks so much for this video. Got new SuperSix EVO with D/A 12 speed and needed to know what tools/equipment from my 11-speed bike I can utilize.
Glad it helped! Tristan
I have a 12 a speed ultegra 11-30, if i change to 11-34 do I need to modify or change any set up of my rd / fd?
You might need to add some B-tension to the rear derailleur and you'll possibly need a new (longer) chain but this will depend on how your bike was initially built -Tristan
I can't seem to find this info anywhere, does the new 12 speed cassette require a spacer underneath on a 11 speed freehub?
No. It goes straight onto an HG 36.8mm freehub body with no spacer -Tristan

Hi there! I have a question, will a 12s Cassette work with a 11s 9100 shifter? A 34 ring on my bike will be amazing.
Definitely not. The spacing between the cogs changed so you may only get decent shifting on 3-4cogs if you're lucky
No, it won't work....there are 11-34 11 speed cassettes though :-) -Tristan
@@WheelworksHandcraftedWheels at least Ultegra?
@@alexmihaiherta there is an R8000 cassette in 11-32t and the HG800 in 11-34... Both are Ultegra quality 👌

I am converting from a Fulcrum 12-speed free hub to Dura Ace 12. What free hub do I need? T U!
Hi Kevin. Assuming your Fulcum wheel has the HG freehub body fitted (not the Campagnolo one) then you don't need to change freehub bodies. -Tristan
Sorry! Should have stated I am converting a CAMPY Fulcrum 12-spd to Dura-Ace 12-spd!
