Power/speed/cadence sensor peaks at 400w

No matter how much harder I go my computer only registers and holds at 400w.  Anybody ever had this issue???

What’s your trainer? Unsupported dumb trainers when paired up using a speed sensor have a max power level of 400 watts.

If I had that problem - I wouldn’t know I had that problem. 

That written, in Cedric’s case, it probably is what Nigel said. 

As Nigel mentioned, if your setup isn’t supported, you’re limited to 400w. More information on that is on the knowledge base.

While your setup isn’t supported, it’s easy to change that. See our hardware page for a full list of what trainers and sensors will give you accurate readings.
