I Zwift with a hard tail MTB on a Kickr. Weird I know but I use my road bike daily on the road and the MTB would be in the shed otherwise.
Anyhow, the MTB having a smaller chainring means I’m always in the top couple of gears on the flat and simply cannot pedal fast enough to put out even a modest 200W on the descents.
I know there is the difficulty slider which makes climbs harder but this seems to have no effect on flats. I’d like the ability to turn up the overall resistance (climbs, flats and descents) to compensate for lower gearing on the bike.
Great product by the way, keep up the good work!
