Thanks for the tip.
Anyway, I took it for a spin, and it looks very much like it’s the KS3 that’s to blame, as the squeaking only occurs 1) when I pedal 2) harder, ie. going “uphill” or with a bit of headwind: The rest of the time, the bike is perfectly silent, save for the KS3 normal ratchet sound.
Here’s a small audio recording (sorry, the windmuf I ordered will be here… next week):
Provided the KS3 must be replaced on that two-year-old EVO: How much does it cost, and how much time does it take for a seasoned Strida professional?
Thank you.
