I’ve just found out that after 4iiii’ acquisition of Stac Zero that they are no longer offering any form of support these trainers… I’ve started having a problem with the power spiking by the power easing, then as my cadence momentarily picking up in response, spiking. I’ve noticed that the magnetic…

I just checked mine and it is rock solid. I would say that is your issue

Many thanks, I’ll tighten it up and give it a go.

I have had an issue with mine when the wheel wasn’t centered, it would have trouble holding power and I’d have something like what you describe - one of the arms would pull away, resistance would drop, then as I start upping my cadence the arm would came back in and add back a lot of resistance (rep…

Thanks for both your replies. I’ve tightened the nut up and made sure everything is centred via the app. I’ve also cleaned the magnets as there was quite a bit of wax impregnated with microscopic bits of metal but it’s still doing it. Possible one of the motors that move the magnets is knackered. An…

That was me, one of my linear actuators that move the magnets failed, followed by the other one just three weeks later. In both cases they froze, the first time a good distance from the wheel making me spin out before any resistance came in, the second time close to the wheel leaving it rideable, …

Thanks - I’ve posted on the other thread. My feeling at the moment is that I’d be throwing good money after bad if I replaced both of them.

Not quite twelve months on and another linear actuator bites the dust. Luckily I had imported a small batch of spares via the nice guys at Actuonix, and I’m back up and spinning again. Less likely now to be a faulty set originally. I’ve probably put about 2,500 miles on it since the last failure…

Center the wheel? I believe the software does this for you automatically. If you ever use the original Stac smartphone App, there is an option to “Find the Wheel” and does exactly what it says, each magnet in turn closes until it touches the rim, records this position then back off to a normally o…

@Stevers I have this same issue. My driveside actuator seems to have konked out after 12,000+km (most of it with TR). I’m looking at the Actuonix site now. Did you buy the 100:1 gear ratio and 6 volt version? Did it come with ribbon installed? FYI. I also came across you discussing this on cyclecha…
