Hi all,
I own a Canyon Ultimate CF SL 7 for about a year now. Last October it started making a squeaking noise – [here is a video where you can hear the noise](https://youtu.be/JY9saW7V5Y8). Below are my observations of when and how the squeaking sound appears:
* It’s only happening while pedaling – it does not matter if standing or seated
* It mostly happens when I push >300 Watts
* It does not appear when riding indoors on a trainer – even when I push >300 Watts
* It seems to happen more often when I push the left pedal downwards, but also not on every stroke
What I tried already to fix it:
* Exchanged the chain
* Exchanged the crank set including front chain rings
* I did not exchange the bottom brackets yet
* Exchanged the casette
* Cleaned the freehub
* Cleaned the jockey wheels
* Checked and adjusted rear and front disc brake
* Greased almost every component on the rear part of my bike
Has anyone had similar issues and found a solution? I appreciate any ideas that could solve the issue. Many thanks!
