Read into the issues of the power accuracy, I would take the Wahoo all day, even with its faults.
From what I’ve gathered the SB20 really have issues with the power meters etc.
Also seems to be very stiff, compared to Wahoo.
Yea you pay a premium price for wahoo but I’d rather have good support and good power accuracy.
Funny that I have read the exact opposite of what you are claiming with regards to power meter accuracy. Just look at DC Rainmakers page. He still doesn’t even have a full review of the Kickr Shift due to inaccurate power data.
And yet the other titan (GP Lama) had excellent results and endorsed the Shift as something he trusts and plans to use for data comparison of other meters. Mixed bag here apparently?
WRT the SB20, there are known issues with stance width being a factor as shown in threads here at the very least, so I don’t think it gets a clean pass either.
Yeah this is what I was referring to. I just forgot the word stance haha.
Seems to be quite a problem from what I have read on other forums 
I have been thinking about getting the Shift as well, even though my Neo 2T has been flawless for more than three years now.
My only real gripe with it (besides having to take my bike on and off) is that it’s really only silent when I am using ERG mode in the small front ring / climbing gears. The flywheel and drivetrain become quite noisy at racing speeds in sim mode. Living in an apartment, this keeps me from racing pretty much at all.
I would also like to be able use ERG mode in the big gears, because right now I am doing low inertia training pretty much exclusively, due to the noise issue.
@GPLama said in his Shift review that you have to be ‘in the right gear’ for ERG mode, or else the power can fluctuate noticably. Anyone have experience with this?
Imagine paying $3,000 for a product and then having to use a rubber band to fix its design flaw.
Imagine paying similar for a Stages SB20 that lacks problem but makes up for it with known accuracy issues which takes far more than a $0.05 rubber band to fix (aka power meter).
I get it. Wahoo could have done better but I fail so see that cable issue as a deal breaker when the rest seems as good or better than similarly priced options.
ETA, per Ray in a recent reply:
As they noted, the magnet in subsequent production versions was made strong. I have yet to have it fall off on the newer bike.
So it looks like they may have corrected that issue in part or whole, at least in Ray’s opinion.
Quite surprised to see this on sale for Black Friday in the UK.

I’m interested in replacing my trainer and my wife’s to get one of these. Does anyone have any experience sharing it between two differently-sized people? Is it too much of a hassle to do daily?
One thing to note: we do use the same crank length so I wouldn’t have to change pedals.
I’m interested in this topic too as I’ve been thinking about buying a Shift to replace my OG Neo, but factoring in the additional cost of a full size rocker plate has left me reluctant to make the change. A big sale would probably convince me to pull the trigger.
Just a quick note because someone is probably going to point out that a common complaint about Wahoo bikes is that the seat post slips. According to the @dcrainmaker review, there is an Allen key on the seat post for the shift that he used which solved the slippage.
Not sure if he or @GPLama can comment further about adjusting the bike and how secure things are if you’re doing daily changes.
We’ve got two different people (me, tall…my wife…short), and use the KICKR Bike in that config. No difference really from a ‘work effort’ standpoint.
The main thing we do is just have a second cheap (round) seatpost with her preferred saddle on it. So just pull out the entire seatpost and swap it in. Using round seatposts reduces the slippage chance.
This is what I do also. Legitimately takes us one minute to swap between Riders. We use a plumbing clamp with the appropriate height set, so it’s just a drop and lock system.
Has anyone replaced the locking mech on the seat post? I find the default one a bit lacking.
Thanks! This is super helpful!
@dcrainmaker or other users - are tou able to freely rotate the cranks backwards like you would on a normal bike? My bike has a rubbing noise which I am waiting for wahoo support to respond on but spinning the cranks in reverse is really difficult
I had the Kickr bike. Actually SEVERAL of them. To deal with the bar and seat slippage issue, wipe the grease off during assembly, then (if new) adjust the clamps so they go smaller/tighter without a post in them (be careful not to get too small) and then take some gritty fiber past and liberally coat the posts and lock them down. It worked for me every time…
One ‘new’ bike had over a tablespoon of grease in each mount tube, and it was just insane! Were they paid by the ounce of grease they used? I’ve never seen that much grease in an area like that. Others were talking about using spacers, and other things, but the fiber paste seemed to do the job.
It’s crazy to hear that people are having the same issues how many years later? I even told the engineers I was in contact with how I fixed/addressed the issues I had. Apparently it was a wasted effort (not that I’m surprised, sadly).
Support told me to replace one on a bike I had. I used a non-QR bolt system. Coupled with the fiber grip paste, it worked (until that bike failed and was replaced).
Have you still got one or did you get fed up with replacements?
No problems rotating the cranks backwards.
They ‘bought it back’, after who knows how many replacements. One died within days of arrival.
I had one that was noisy on backpedaling, but it was replaced eventually because it was pretty noisy pedaling forward too. I think it was dropped in shipping, the box was kind of a mess.
I kept thinking that Wahoo needed to use a better system of packaging because the contents appeared to be prone it issues during shipping, and they should have been able to shield it from some of it. Now, the fork that pierced the box was a total disaster that no one could prevent, and the dropped one, and the one delivered upside down too. 
But I find it hard to believe that they/I had so many issues. (Unless their refurbishment process was not doing a good job?)
