Hello hope someone can help I’m new to cycling.
I am using a basic hybrid bike 18 speed and wahoo speed and cadence sensors and dumb trainer (lifeline tt-01) . I don’t know much about gears. Zwift will only pick up speed when front gear is on largest cog and back is more responsive on smallest 6 but does work on 5 and 4 also. On any other gear combination zwift avatar stay Stationary and gears feel too loose on any other combination also. Not sure if I should tighten the trainer setting at the back. The trainer has manual dial from 1-6. 1 being the most resistance. I’m using it on 1 that’s why I’m thinking I need to tighten the manual cog at the back. The candence sensor is on the pedal arm but near the centre. Not sure if placement makes any difference.
