So does that mean we all have to buy a Wahoo Kickr V5?
Wahoo have intentionally increased the power that trainer reads to compensate for drivetrain loses. This immediately makes this the only trainer a serious Zwift racer can use. Look it up.
This seems heroically idiotic. Are we then going to all have to buy the next trainer that universally overreads power?
Further, these trainers are a million miles from dead accurate. Many, do not have actual strain gauges. They use a rudimentary flywheel speed equations. They also have poor temperature compensation. Short story, they are far from accurate.
Now, some us own significantly more accurate power meters. Be that Favero pedals or spider based PMs like SRMs. It seems utterly illogical that we should be using the far less accurate devices to measure our power output.
Many serious cyclists that use Zwift for training, but also ride in the real world, prefer to use the same power meter for consistency.
Being forced to use the random number generator (insert most smart trainers here) to race is backwards logic. Particularly, if Zwift is actually intending to eventually be a fair racing platform.
If this isn’t addressed we are going to see a continual escalation of inflated power metrics by smart trainer manufactures. It’s already begun. Literally, any smart trainer manufacture releasing a new model now, has to calibrate it to match or further overread what the current Kickr V5 is reading. Otherwise, not a single racer could buy it.
So, I’m all for the dual recording, however all users should be using an actual power meter for power measurement. Not a cheap speed sensor masquerading as a measurement device.
Personally. I use my Favero pedals for all my riding. If I used my poorly designed Wahoo Kickr Core, I’d sometimes be World Tour or sometimes be weak, depending on it’s poor temperature compensation.
So, going forward @xflintx should we not be using the far more accurate devices many of us already own to control the gaming? Or, are we just going to accept that power, the one athlete generated metric that controls all of the racing, is never going to be calibrated for any kind of accuracy.
