Zwift Speed varies from 0 to 60+

I have a between inride 100

I know this is more of a btwin support question but can’t seem to contact them.

I ride TREK DX 7.2

TIRES are BONTRAGER 700X35

GARMIN SPEED AND CADENCE SENSOR

There are three settings where back wheel rests on the motar.

  1. 26" for MTB
  2. 700mm 27x1.5 Road
  3. 28" Other bikes

I am guessing I should be on position 2.
But in 1 and 2 I am unable to make the tire sit and lock it in place. It is not aligning propeely so as to lock it in place.

So I am using it at 3rd setting

On the zwift app I am selecting tire size as 27x1.5… I don’t see 28".

Pls help. My avatar is getting off the damm bike turns around and glares at me.

Decathalon says since my bike is hybrid…I must use the third option…whichbis what I have been using but that’s where I am experiencing slow speeds.or zero speeds
