MTB/hybrid/road

Quick question. 

Does it matter what bike I use on Zwift. I don’t want to put my road bike on the turbo as it seems a waste. I am using a Trek Hybrid with a Tacx trainer road tyre.

Obviously weight and aerodynamics make no difference on the trainer but wondered if gearing, crank lengths etc. might be important? And if so how important?

 

 

Hi, 

It only matters to your legs. (I am guessing).

I use my Boardman Hybrid on mine. It’s a 2x10 with 50/34 front and 11-32 on the back. Works brilliantly and feels little difference from my Di2 Giant.
