Tacx Flow T2240 Flywheel Clicking
I have purchased a tacx flow so i can use power to train with in the long winter months in the north of the uk.When the device is calibrated i think it measures how long the wheel takes to slow down and gives you a reading from a negative number through to positive numbers. My experience with the Flow is quite old so I don't know if Tacx has fixed the problems with it since it was first released. However, back then I did a fair number of tests on the Flow against a statically checked Power Tap. The good news is that when the Tacx rolldown calibration number was held constant, over a several month period the Flow read consistently.
The bad news is that it was consistently off, especially in erg mode. Paint tool sai full version. In addition, I tried altering the scale factor, the rolldown calibration (i.e., the roller-to-tire pressure), and the mains wattage and was unable to get the Flow to read accurately.Edit: You don't need to keep the rolldown calibration at zero.
I do a roll-down calibration every week or two to make sure it's still 'on' - I also check at the end of a session when the tyre is warm. I've never had any problem adjusting the pressure to get a reading around zero.On the other hand, I've found the Flow VERY picky in relation to tyres. In the same setup, same wheels etc., and with proper calibration, it will display up to 50 watts difference for the same output, depending on the tyre I use.FWIW, i've found Continental GP 4000s pretty good at keeping things honest.In other words, get the grippiest tyre you can, and that slipping rear wheel may be a thing of the past.

I have a TACX flow as well as a SRM and here are my observations.If I set the tyre pressure to 100 PSI, I do the roll down calibration after 10 minutes of riding, I adjust the knob to get a reading of '0', and I always ride my efforts in the 53 x 12, then the ergo mode is very consistent for not just the training session, but from month to month.I use a bright orange indoor specific tyre for all my indoor workouts. I haven't been experiencing tyre slip and the tyre is wearing so slowly that the wear is almost imperceptible.If when doing the roll down calibration, I don't adjust it to get a reading of '0', the ergo mode will read differently.
If you were to experience tyre slip, you could set the knob to a different value that doesn't experience tyre slip, but make sure you always strive for that value as consistency is what you need.The TACX flow is around 50 watts optimistic when set to 350 in the ergo mode, although the lower my cadence the less optimistic the Tacx is. Forget the gyrations. Sell and get what you can for the Tacx, and then parlay that on a 'real', practical ergometer - the Computrainer.
No this isn't an ad - heck, I don't even own one, but I've used them enough to know they're light-years better (read: accurate, consistent, reliable) than any of the 'wannabes', aka Tacx and Elite. FWIW, I own an Elite Real Axiom and for what I ask of it - varying terrain tempo and endurance riding - it's great as it breaks the monotony, but I also have a PT so I don't care about the wattage numbers the Elite is telling me. To be honest, they're practically worthless, and that's even against itself as the thing takes about 20 minutes to stabilize due to the combined usage of fluid and magnetism to provide resistance.My $0.02CAN worth.
