Good day all.

I recently bought the above trainer for my 29er mtb. I have a 29er wheel with an indoor tyre mounted on the bike. I noticed in the manual there is a 30 diameter roller and 45 diameter roller setting. I am however not sure what the difference is and which setting the best is for my setup.

Can anyone please assist?

Thank you in advance.

Hi

It's the elastogel roller diameter. This setting is important only if you connect the trainer on a non Elite device (for example a Garmin device), where you have to set the circumference value accordingly.
In your case, the Qubo Power Mag has a 45mm diameter roller.

Thank you so much.
