Configuring Zwift correctly


I have setup zwift with my Elite Crono Fluid turbo and Garmin speed/cadence sensor it works fine - however, it reads my speed and the power (I don’t have a power meter, but I don’t need one to know) watts reading more than it should.

I’m sure there is somewhere to configure height/weight/bike size etc. could someone point me to this and any other tips on calibrating?



Hi Stephen, 

Since the Elite Crono Fluid is compatible with Zwift the reading should be reasonably accurate, but bare in mind it will never be as accurate as power meter or high end trainers. 

You can change the weight and height in one of the following:

  1. Zwift -> User Profile
  2. Mobile Zwift App -> Settings -> Profile
  3. -> Log in -> Edit Profile

To customise your avatar including bikes, wheelsets, jerseys etc.You need to go to customise screen in Zwift. 


I hope it helps, Ride On!

I have the Elite Crono Fluid and Zwift recommends using L4 - however, I felt that this was not correct and sure enough after installing the new Garmin Vector 3 power pedals I can now see the difference between the real power readings and those predicted by Zwift Power (ZP).

I put my Elite Crono Fluid on Level 1 and for the first  5mins  found the ZP readings to be higher than the real power readings:
ZP=150w / Real=140w
ZP=250w / Real=200w
ZP=350w / Real=265w

But as time went by the resistance seemed to keep increasing so after about  30mins  the real power readings were becoming higher than the ZP readings (but only at the upper end!):
ZP=150w / Real=100w
ZP=250w / Real=265w
ZP=350w / Real=420w

After 40mins:
ZP=150w / Real=150w
ZP=250w / Real=320w

After 50mins  all real readings were higher than ZP:
ZP=150w / Real=175w
ZP=250w / Real=340w

So basically the resistance of this turbo increases with time and in a non-linear way.

Another day I recorded the real power readings against a set speed (recorded by a garmin speed sensor) and got the following results as time progressed:


  • 170w after 5mins
  • 175w after 10mins
  • 170w after 20mins
  • 186w after 30mins
  • 190w after 40mins
  • 194w after 50mins
  • 280w after 2hrs


  • 200w after 5mins
  • 213w after 10mins
  • 215w after 20mins
  • 220w after 30mins
  • 246w after 40mins
  • 250w after 50mins
  • 400w after 2hrs (yes 400w!!)


  • 276w after 5mins
  • 300w after 10mins
  • 315w after 20mins
  • 380w after 30mins
  • 430w after 40mins
  • 460w after 50mins

In summary the power calculated by Zwift (ZP) is not very useful, especially when racing and you’re trying to hit those higher numbers!
