Wahoo Kickr v1 with a 10sp Shimano cassette on it. I’m gonna switch to a 11sp rear derailleur. Anyone know if I can fit a 11sp on the hub? Thanks
I’ve got a v2 that’s now running an 11s Shimano cassette (came with a 10s). I can’t see any drama, although you may (??) require a very thin spacer for the 11s cassette. But I don’t see anything that can’t be easily resolved. I bet it will fit sraight on, that’s what I’ve always found with non-Mavic road wheels I switched from 10 to 11.

Yup…you’ll probably need the spacer (counter-intuitive, but here we are!)
For all intents and purposes, the Shimano freehub was unchanged since the days of 8spd. While I don’t think I ever used an 11spd cassette on my 8-spd DA hubs, I know I definitely used 10 spd.
So putting an 11spd cassette on your 10spd freehub should be fine (with spacer being likely needed).

I can’t believe it, I actually went to RTFM 
How did you go?
Appreciate you reading the manual but cassette replacement instructions doesn’t actually answer the question … as per:
Drivetrain Compatibility for KICKR, CORE, and MOVE trainers
Says:
This article applies to KICKR version 4 (2018) and newer, KICKR CORE, and KICKR MOVE. In order to identify your trainer, please see this Wahoo wheel-off smart trainer identification article. In order to confirm if your bicycle’s frame is compatible with a KICKR, CORE, or MOVE, please see the bicycle frame compatibility articles for KICKR, CORE, or MOVE. If you have frame or drivetrain compatibility questions for pre-v4 KICKRs, please contact our support team with the make and model of your rear derailleur, cog count, and high/low tooth count of your cassette, an image of both, and the serial number of the trainer and we are happy to help.
My question is for a Kickr v1 and it’s unclear for anything before Kickr v4 as per above. Think it should be OK but will pull the cassette, look for spacer and measure the freehub …
But that’s an article for a different purpose. The HG freehubs are all the same across the various version hence my link, I’ll check the cassette on my Kickr v2 to see if I’m running a spacer (I’m nearly certain I’m not). Are you going to be using the range of the cassette through, or just erg mode? If erg mode I’d just keep the 10s cassette on and find the gear that works best/quietest.
I think we’re talking about the same issue - you’re going to be using an 11s bike on a Kickr v1 that currently has a 10s cassette on it and you want to confirm an 11s cassette will fit the Kickr?
Correct, 11s bike on a Kickr v1 that has the original 10s cassette.
I thought there were different length HG freehubs. If they’re the same across all the Kickr versions, I should be fine then as the latest ones are compatible.
I’m using ERG mode and never change gears so perhaps I can just get away the 10s. I’ll give that a go first. Thanks

Sorry it took a while but I took the 11s free hub off my V2 Kickr today - no spacer.
