Set the rolling resistance for Kickr in sim mode.


(Ian Munro) #1

Could you add a feature to allow the base resistance of kickr in sim mode?
Kickr’s sim mode function appears to support the setting of the rolling resistance of the bike. By being able to alter this (maybe just in prefs.xml), it would be possible to set up the kickr so that it doesn’t have to spin as such a high rpm making it a bit quieter. It would also allow it to work better with bikes such as mtbs that don’t always have the upper gear range needed.

Hi Ian, 

That’s pretty good point. Let me add it on the list for you. What you can do in mean time is create a workout with only one very long ‘‘free ride’’ section. In this mode you can control the resistance manually using your keyboard ‘’-’’ and ‘’+’’ keys or theZwift Mobile app.

Ride On!

I wonder if this could be included in a more advanced method for setting the trainer difficulty which builds upon the existing slider.

At present the slider will effectively decrease the gradient of inclines which I’ve found to be essential to avoid spinning out on the downhills on my kickr but at the same time makes the uphills a bit disappointing.

What might be useful are separate scaling factors applied to positive, flat and negative gradients. The positive value could be left at 1 to keep uphill gradients at their true values, while the flat and negative values could be used to increase the difficulty of the flats and declines.

So ideally I could have a 13 degree incline at its true difficulty, followed by a “flat” section which has been adjusted up to 5 degrees, and a -13 degree decline which is adjusted to -2 degrees.

This would be a great feature. Currently I ride with a MTB with a triple crank, so have a 42/32/24 chainring. Other guys using MTB double cranks will only have a 36/24 or 38/26. This makes it impossible to race as the guys with road cranks have 50/52 or 53T big rings, it’s absolutely impossible to keep up with them if you don’t have a road crank.

I asked about adding this before as a “chainring offset” type of feature, but yes, a change in the resistance of a “flat” road equates to the same thing.
