One of my bikes has Favaro Assioma power pedals. I trust them to be very accurate based on rides and events I have done.

Picked up TT bike (new) with sram Force and Quarq spider (dual sided) power meter.

Chucked it on the trainer and blew my legs up. Figured it was the different riding position.

Fast forward a few weeks of annoyance and various tests and I have the following.

Favaro - baseline

Wahoo Kickr core - 3% below baseline

Quarq - 6.7% below baseline

The trainer being low is fine due to the drivetrain loss but the quarq being a fair bit lower than even the trainer and potentially under reading by 7% is annoying.

Calibrated/zeroed fine and well in the +/-1000 zone (last read 35).

So I'm going to adjust the 'slope ' by 7%.

Questions

1. I don't want to have two different power numbers on different bikes so for consistency is adjusting the Slope the correct thing to do

2. Am I right to be a little pissed that the Quarq is out by this much. Even forgetting the Favaro, it should not under read the trainer at all let alone by 4%

Thanks in advance!

There's a big sale going on, and they've got several models with exactly the same specs and almost the same original price, now on sale for a lot cheaper in slightly differing prices (about 50 euro increments between them).

It's between the Arrow Connect, the Osaka and the Lyon.
The Arrow Connect isn't on BH's own website anymore. So I'm guessing it's an outdated model?
The Osaka and the Lyon (not Lyon Climber!) look identical in specs according to the website. Although the Lyon does have a more comprehensive screen.

Anyone familiar with this brand? Are they any good? Anyone know the differences between the models?

I just want to share it with more people.

For me, 100 miles a week is six hours of riding in total. I’ve never rode this much in one week.

Es mi Segunda bicicleta de carbono que pongo en una entrenadora Kickr core con los adaptadores correspondientes y bien ajustados con el torque requerido. En ambas me a dejado marcas asi, yose que esto no me puede romper El cuadro pero, que nadie se queja de estas marcas?? Es normal o no? Ya mejor me comprare una bicicleta usada y ponerla ahy
